//[END OF VERSION]

  K.O.L. - is a set of objects to create small programs
  with the Delphi, but without the VCL. KOL allows to
  create executables of size about 10 times smaller then
  those created with the VCL. But this does not mean that
  KOL is less power then the VCL - perhaps just the opposite...

  KOL is provided free with the source code.

   Please note, that KOL does not use keyword 'class'. Instead,
   poor Pascal 'object' is the base of our objects. So, remember,
   how we worked earlier with such Object Pascal's objects:
|<br>
   - to create objects dynamically, use P<objname> instead of
     T<objname> to allocate a pointer for dynamically created
     object instance;
|<br>
   - remember, that constructors of objects can not be virtual.
     Override procedure Init instead in your own derived objects;
|<br>
   - rather then call constructors of objects, call global procedures
     New<objname> (e.g. NewLabel). If not, first (for virtualally
     created objects) call New( ); then call constructor Create
     (which calls Init) - but this is possible only if the constructor
     is overriden by a new one.
|<br>
   - the operator 'is' is not applicable to objects. And operator 'as'
     is not necessary (and is not applicable too), use typecast to desired
     object type, e.g.: "PSomeObjectType( C )" inplace of "C as TSomeClassType".
|<br>
|<hr>
     Also remember, that IF [ MyObj: PMyObj ] THEN

     NOT[ with MyObj do ] BUT[ with MyObj^ do ]

     Though it is possible to skip '^' symbol when accessing member
     fields, methods, properties, e.g. [ MyObj.Execute; ]

  Several conditional symbols can be used in a project
  (Project | Options | Directories/Conditional Defines)
  to change code generated a bit. There are following:
|<pre>

  LINUX                 - version for Linux (only PAS_VERSION)
  PAS_VERSION           - to use Pascal version of the code.
  PARANOIA              - to force short versions of asm instructions (for D5
                          and below, D6 and higher use those instructions always).
  SMALLEST_CODE         - to create minimal code application (affected:
                          (o) SimpleGetCtlBrushHandle - returns solid silver brush
                              always;
                          (o) _NewWindowed
                              - only default system font used by default;
                              font of the parent control is not applied to its
                              children automatically (but see SMALLEST_CODE_PARENTFONT);
                              - fBrush always set to NIL by default (parent Brush
                              is not applied);
                          (o) WndProcDoEraseBkgnd
                              - child controls windows are not created in WM_ERASEBKGND
                              if were not created earlier (in most case, all OK
                              with this - controls are created BTW);
                              - SetBkColor, SetBkMode, SetBrushOrgEx are not
                              called (all OK therefore)
                          (o) by default, NOT_UNLOAD_RICHEDITLIB is defined if
                              UNLOAD_RICHEDITLIB is not defined in project options
                              (this minimizes finalization section).
                          (o) _NewControl
                              - BoundsRect initialized with a rectangle
                                (aParent.fMarginLeft, aParent.fMarginTop,
                                 aParent.fMarginLeft+64, aParent.fMargin+64)
                                rather then with (aParent.fMargin+aParent.fMarginLeft,
                                aParent.fMargin+aParent.fMarginTop,
                                aParent.fMargin+aParent.fMarginLeft+64,
                                aParent.fMargin+aParent.fMarginTop+64).
                                In most cases this is enough.
                          (o) Int2Hex
                              there are no check for second perameter > 15
                          (o) .... other see in code
  SMALLER_CODE          - like smallest code, but fuctionality is the same.
                          The speed can be lower therefore.
  SMALLEST_CODE_PARENTFONT - Parent font therefore is applied for child controls,
                             but initially only.
  USE_NAMES             - to use property Name with any TObj. This makes also
                          available method TObj.FindObj( name ): PObj.
  (USE_CONSTRUCTORS     - to use constructors like in VCL. Note: this option is
                          not carefully tested!)
  USE_CUSTOMEXTENSIONS  - to extend TControl with custom additions.
  UNICODE_CTRLS         - to use Unicode versions of controls (WM_XXXXW messages,
                          etc.)
  USE_MHTOOLTIP         - to use MHTOOLTIP.
  USE_OnIdle            - to use OnIdle event
  ENUM_DYN_HANDLERS_AFTER_RUN - to allow all the events handling even when
                        AppletTerminated become TRUE.
  BUTTON_DBLCLICK       - to prevent clicking buttons with double click,
                          this takes smaller code but buttons can not
                          be pressed with mouse fast. When SMALLEST_CODE on,
                          this option also is on.
  ALL_BUTTONS_RESPOND_TO_ENTER - obvious (by default, buttons respond to key
                        SPACE, since those are working this way in Windows).
  CLICK_DEFAULT_CANCEL_BTN_DIRECTLY - to prevent visual effect of default/cancel
                             button pressing with Enter/Escape keys. Also, button
                             don't become focused in such case.
  DEFAULT_CANCEL_BTN_EXCLUSIVE - to disable assigning to a button properties
                             DefaultBtn and CancelBtn simultaneously.
  NO_DEFAULT_BUTTON_BOLD - to prevent DefaultBtn to be visually with
                             a bold border.
  BITBTN_DISABLEDGLYPH2 - to restore old behaviour of multi-glyph bitbtn, when
                          index 2 was used to represent the button in disabled
                          state, and glyph with index 1 was used forpressed dtate.
                          Now by default index 1 corresponds to the disabled state,
                          and index 2 to the pressed state, i.e. these are swapped.
  ESC_CLOSE_DIALOGS     - to allow closing all dialogs with ESCAPE.
  KEY_PREVIEW           - form also receive WM_KEYDOWN (OnKeyDown event fired)
  SUPPORT_ONDEADCHAR    - to support OnKeyDeadChar event in responce to
                          WM_DEADCHAR, WM_SYSDEADCHAR
  OpenSaveDialog_Extended - to allow using custom extensions for OpenSaveDialog.
  AUTO_CONTEXT_HELP     - to use automatic respond to WM_CONTEXTMENU to call
                        context help.
  NOT_FIX_CURINDEX      - to use old version of TControl.SetItems, which could
                        lead to loose CurIndex value (e.g. for Combobox)
  NOT_FIX_MODAL         - not to fix modal (if fixed, click on any window
                          activates the application. If not fixed, code is
                          smaller very a little, but only click on modal form
                          activates the application). This does not fix calling
                          MsgBox though.
  NEW_MODAL             - to use extended modalness.
  USE_SETMODALRESULT    - to guarantee ModalResult property assigning handling.
  USE_MENU_CURCTL       - to use CurCtl property in popup menu to detect which
                        control initiated a pop-up.
  NEW_MENU_ACCELL       - to use new menu accelerators handling, without
                        AcceleratorTable (not tested for all cases)
  USE_DROPDOWNCOUNT     - to force setting combobox dropdown count.
  NOT_UNLOAD_RICHEDITLIB - to stop unload Rich Edit library in finalization
                        section (to economy several byte of code).
  NOT_USE_RICHEDIT      - not use richedit (it will not be possible to create richedit)
  USE_PROP              - to use GetProp / SetProp (old style) in place of
                          Get / SetWindowLong( wnd, GWL_USERDATA... ) (slower?)

  PROVIDE_EXITCODE      - PostQuitMessage( value ) assigns value to ExitCode
  INITIALFORMSIZE_FIXMENU - form size initially is really the same as defined at
                          design time even for forms having main menu bar
  USE_GRAPHCTLS         - to use graphic (non-windowed) controls
  GRAPHCTL_XPSTYLES     - to use XP themed Visual styles for drawing graphic
                          controls. This does not affect windowed controls
                          which visual style is controlled by the manifest.
  GRAPHCTL_HOTTRACK     - to use hot-tracking also together with XP themed
                          graphic controls (otherwise only static XP themed
                          view is provided). Also, turn this option on if you
                          want to handle OnMouseEnter and OnMouseLeabe events
                          for graphic controls.
  ICON_DIFF_WH          - to support icons having Width <> Height
  AUTO_REPLACE_CLEARTYPE- to replace automatically CLEARTYPE_QUALITY fonts
                          with ANTIALIASED_QUALITY when running under elder
                          Windows version than XP.

  NEW_GRADIENT - to use new gradient painting by homm (fast).
  OLD_ALIGN    - to prevent using new Align by Galkov (new Align is faster).
  FILE_EXISTS_EX - to use more correct (but a bit large code in FileExists functon)
  NOT_USE_AUTOFREE4CONTROLS - from 2.40, most of control sub-objects are destroying
                             using Add2AutoFree (smaller code). This option returns
                             to previous behaviour (to compare size). Will be
                             deprecated in future versions.
  ENDSESSION_HALT - to halt the process when WM_ENDSESSION comes.
  FILESTREAM_POSITION   - in PAS_VERSION, Stream..fData.fPosition always show
                          current position (for debug purposes)
  PSEUDO_THREADS        - to use pseudo-threads instead of normal threads.
  WAIT_SLEEP            - to sleep 10 ms in WaitForMultipleObjects loop (for PSEUDO_THREADS)
  DEBUG_MENU            - to debug menu.
  DEBUG_GDIOBJECTS      - to allow counting all the GDI objects used.
  CHK_BITBLT            - to check BitBlt operations.
  DEBUG_ENDSESSION      - to allow debugging WM_ENDSESSION handling.
  DEBUG_CREATEWINDOW    - to debug CreateWindow.
  CRASH_DEBUG           - to fill object memory with $DD before freeing it
                          (program really crashes when the object is
                          attempted to destroy more then once and in most
                          cases when a destroyed object is accessed after the
                          destruction).
  DEBUG                 - other debugging.
  EXTERNAL_DEFINES      - if count of options necessary to set is very large
                          Delphi ignores past of those. To avoid this problem,
                          set only this option in Project's options, and place
                          all other options to ExternalDefines.inc file as a
                          sequence of {$DEFINE ... directives.
                          But note, such file should be located in a
                          project directory, but not in the directory where KOL.pas
                          is located. This is enough to provide different sets
                          of defines for each project.

     |<br>
        Use RefInc..RefDec to provide a block of code, where

        If You want to release object at the end of block RefInc..RefDec,
        do it immediately BEFORE call of last RefDec (to avoid situation,
        when object is released in result of RefDec, and attempt to

         Actually, this "function" is a procedure and does not return

        некотором участке кода (если есть такая необходимость).

//[TCanvas DEFINITION]
  TCanvas = object( TObj )
  {* Very similar to VCL's TCanvas object. But with some changes, specific
     for KOL: there is no necessary to use canvases in all applications.
     And graphic tools objects are not created with canvas, but only
     if really accessed in program. (Actually, even if paint box used,
     only programmer decides, if to implement painting using Canvas or
     to call low level API drawing functions working directly with DC).
     Therefore TCanvas has some powerful extensions: rotated text support,
     geometric pen support - just by changing correspondent properties
     of certain graphic tool objects (Font.FontOrientation, Pen.GeometricPen).
     See also additional Font properties (Font.FontWeight, Font.FontQuality,
     etc. }

       |<br>
       To use a form as a modal, it is possible to make it either auto-created
       or dynamically created. For a first case, You (may be prefer to hide a
       form after showing it as a modal:
       !
       !  procedure TForm1.Button1Click( Sender: PObj );
       !  begin
       !    Form2.Form.ShowModal;
       !    Form2.Form.Hide;
       !  end;
       !
       Another way is to create modal form just before showing it (this economies
       system resources):
       !
       !  procedure TForm1.Button1Click( Sender: PObj );
       !  begin
       !    NewForm2( Form2, Applet );
       !    Form2.Form.ShowModal;
       !    Form2.Form.Free; // Never call Form2.Free or Form2.Form.Close
       !  end;               // but always Form2.Form.Free; (!)
       !
       In samples above, You certainly can place any wished code before and after
       calling ShowModal method.
       |<br>
       Do not forget that if You have more than a single form in your project,
       separate Applet object should be used.

       When a status text is set first time, status bar window is created
       (always aligned to bottom), and form is resizing to preset client height.
       While status bar is showing, client height value is returned without
       height of status bar. To remove status bar, call RemoveStatus method for
       a form.

       By default, text is left-aligned within the specified part of a status
       window. You can embed tab characters (#9) in the text to center or
       right-align it. Text to the right of a single tab character is centered,
       and text to the right of a second tab character is right-aligned.
       |<br>
       If You use separate status bar onto several panels, these automatically
       align its widths to the same value (width divided to number of panels).
       To adjust status panel widths for every panel, use property StatusPanelRightX.

    //======== List View specific events:
    property OnEndEditLVItem: TOnEditLVItem read fOnEndEditLVITem write SetOnEndEditLVItem;
    {* |<#listview>
       Called when edit of an item label in ListView control finished. Return
       True to accept new label text, or false - to not accept it (item label
       will not be changed). If handler not set to an event, all changes are
       accepted. }

    property OnLVDelete: TOnDeleteLVItem read fOnDeleteLVItem write SetOnDeleteLVItem;
    {* |<#listview>
       This event is called when an item is deleted in the listview.

       Called for every deleted list view item. }
    property OnDeleteAllLVItems: TOnEvent read fOnDeleteAllLVItems write SetOnDeleteAllLVItems;
    {* |<#listview>
       Called when all the items of the list view control are to be deleted. If after
       returning from this event handler event OnDeleteLVItem is yet assigned,
       an event OnDeleteLVItem will be called for every deleted item. }
    property OnLVData: TOnLVData read fOnLVData write SetOnLVData;
    {* |<#listview>
       Called to provide virtual list view with actual data. To use list view as
       virtaul list view, define also lvsOwnerData style and set Count property
       to actual row count of the list view. This manner of working with list view
       control can greatly improve performance of an application when working with
       huge data sets represented in listview control. }

    property OnCompareLVItems: TOnCompareLVItems read fOnCompareLVItems write fOnCompareLVItems;
    {* |<#listview>
       Event to compare two list view items during sort operation (initiated by

       while it is sorting - results can be unpredictable! }
    property OnColumnClick: TOnLVColumnClick read fOnColumnClick write SetOnColumnClick;
    {* |<#listview>
       This event handler is called when column of the list view control is clicked.

       |<#listbox>
       |<#combo>
       This event can be used to implement custom drawing for list view, list box, dropped
       list of a combobox. For a list view, custom drawing using this event is possible
       only in lvsDetail and lvsDetailNoHeader styles, and OnDrawItem is called to draw
       entire row at once only. See also OnLVCustomDraw event. }

    property OnLVCustomDraw: TOnLVCustomDraw read FOnLVCustomDraw write SetOnLVCustomDraw;
    {* |<#listview>
       Custom draw event for listview. For every item to be drawn, this event
       can be called several times during a single drawing cycle - depending on
       a result, returned by an event handler. Stage can have one of following
       values:
       |<pre>
       CDDS_PREERASE
       CDDS_POSTERASE
       CDDS_ITEMPREERASE
       CDDS_PREPAINT
       CDDS_ITEMPREPAINT
       CDDS_ITEM
       CDDS_SUBITEM + CDDS_ITEMPREPAINT
       CDDS_SUBITEM + CDDS_ITEMPOSTPAINT
       CDDS_ITEMPOSTPAINT
       CDDS_POSTPAINT
       </pre>
       When called, see on Stage to get know, on what stage the event is
       activated. And depend on the stage and on what you want to paint,
       return a value as a result, which instructs the system, if to use
       default drawing on this (and follows) stage(s) for the item, and if
       to notify further about different stages of drawing the item during
       this drawing cycle. Possible values to return are:
       |<pre>
       CDRF_DODEFAULT - perform default drawing. Do not notify further for this
                      item (subitem) (or for entire listview, if called with
                      flag CDDS_ITEM reset - ?);
       CDRF_NOTIFYITEMDRAW - return this value, when the event is called the
                      first time in a cycle of drawing, with ItemIdx = -1 and
                      flag CDDS_ITEM reset in Stage parameter;
       CDRF_NOTIFYPOSTERASE - usually can be used to provide default erasing,
                      if you want to perform drawing immediately after that;
       CDRF_NOTIFYPOSTPAINT - return this value to provide calling the event
                      after performing default drawing. Useful when you wish
                      redraw only a part of the (sub)item;
       CDRF_SKIPDEFAULT - return this value to inform the system that all
                      drawing is done and system should not peform any more
                      drawing for the (sub)item during this drawing cycle.
       CDRF_NEWFONT - informs the system, that font is changed and default
                      drawing should be performed with changed font;
       |</pre>
       If you want to get notifications for each subitem, do not use option
       lvoOwnerDrawFixed, because such style prevents system from notifying
       the application for each subitem to be drawn in the listview and only
       notifications will be sent about entire items.

       coOwnerDrawFixed or coOwnerDrawVariable for combobox. At least, the
       control should have such option while creating it (after showing it
       the first time it is possible to change its options to avoid owner
       drawing later). }

    //======== Toolbar specific methods:
    procedure TBAddBitmap( Bitmap: HBitmap );
    {* |<#toolbar>
       Adds bitmaps to a toolbar. You can pass special values as Bitmap to
       add one of predefined system button images bitmaps:
       |<br> THandle(-1) to add standard small icons,
       |<br> THandle(-2) to add standard large icons,
       |<br> THandle(-5) to add standard small view icons,
       |<br> THandle(-6) to add standard large view icons,
       |<br> THandle(-9) to add standard small history icons,
       |<br> THandle(-10) to add standard large history icons,
       (in that case use following values as indexes to the standard and view
       bitmaps:
       |<br>
       STD_COPY, STD_CUT, STD_DELETE, STD_FILENEW, STD_FILEOPEN, STD_FILESAVE,
       STD_FIND, STD_HELP, STD_PASTE, STD_PRINT, STD_PRINTPRE, STD_PROPERTIES,
       STD_REDO, STD_REPLACE, STD_UNDO,
       |<br>
       VIEW_LARGEICONS, VIEW_SMALLICONS,
       VIEW_LIST, VIEW_DETAILS, VIEW_SORTNAME, VIEW_SORTSIZE, VIEW_SORTDATE,
       VIEW_SORTTYPE (use it as parameters BtnImgIdxArray in TBAddButtons or
       TBInsertButtons methods, and in assigning value to TBButtonImage[ ]
       property).
       Added bitmaps have indeces starting from previous count of images
       (as these are appended to existing - if any).
       |<br>
       Note, that if You add your own (custom) bitmap, it is not transparent.
       Do not assume that clSilver is always equal to clBtnFace. Use API
       function CreateMappedBitmap to load bitmap from resource and map
       desired colors as you wish (e.g., convert clTeal to clBtnFace). Or,
       call defined in KOL function LoadMappedBitmap to do the same more easy.
       Unfortunately, resource identifier for bitmap to pass it to LoadMappedBitmap
       or to CreateMappedBitmap seems must be integer, so it is necessary to
       create rc-file manually and compile using Borland Resource Compiler to
       figure it out. }

    function TBAddButtons( const Buttons: array of PKOLChar; const BtnImgIdxArray: array
              of Integer ): Integer;
    {* |<#toolbar>
       Adds buttons to toolbar. Last string in Buttons array *must* be empty
       ('' or nil), so to add buttons without text, pass ' ' string (one space
       char). It is not necessary to provide image indexes for all
       buttons (it is sufficient to assign index for first button only).
       But in place, correspondent to separator button (defined by string '-'),
       any integer must be passed to assign follow image indexes correctly.
       See example.
       |*Toolbar adding buttons sample.
       Code below shows how to call TBAddButtons method to add two buttons with
       a separator between these buttons. idxNew and idxOld are integer
       expressions assigning image indexes to buttons 'New' and 'Old'. This
       indexes are zero-based and refer to bitmap images, added earlier (either
       in creating toolbar by call of NewToolbar or later in call of TBAddBitmap).
       !
       !     TBAddButtons( [ '&New', '-', '&Old', '' ], [ idxNew, 0, idxOld ] );
       !
       |*
       To add check buttons, use prefix '+' or '-' in button definition
       string. If next character is '!', such buttons are grouped to a
       radio-group. Also, it is possible to use '^' prefix (must be first) to
       define button with small drop-down section (use also OnTBDropDown event
       to respond to clicking drop down section of such buttons).
       |<br>
       This function returns command id for first added button (other
       id's can be calculated incrementing the result by one for each
       button, except separators, which have no command id).
       |<br>

    function RE_FmtStandard: PControl;

       "Transparent" method (returns @Self as a result), which (when called)
       provides "standard" keyboard interface for formatting Rich text (just
       call this method, for example:
       !    RichEd1 := NewRichEdit( Panel1, [ ] ).SetAlign( caClient ).RE_FmtStandard;
       Following keys will be maintained additionally:
       |<pre>
       CTRL+I - switch "Italic",
       CTRL+B - switch "Bold",
       CTRL+U - switch "Underline",
       CTRL+SHIFT+U - swith underline type
                    and turn underline on (note, that some of underline styles
                    can not be shown properly in RichEdit v2.0 and lower,
                    though RichEdit2.0 stores data successfully).
       CTRL+O - switch "StrikeOut",
       CTRL+'gray+' - increase font size,
       CTRL+'gray-' - decrease font size,
       CTRL+SHIFT+'gray+' - superscript,
       CTRL+SHIFT+'gray-' - subscript.
       CTRL+SHIFT+Z - ReDo
       |</pre>
       And, though following standard formatting keys are provided by RichEdit
       control itself in Windows2000, some of these are not functioning
       automatically in earlier Windows versions, even for RichEdit2.0. So,
       functionality of some of these (marked with (*) ) are added here too:
       |<pre>
       CTRL+L - align paragraph left,           (*)
       CTRL+R - align paragraph right,          (*)
       CTRL+E - align paragraph center,         (*)
       CTRL+A - select all,                     (*)
       double-click on word - select word,
       CTRL+Right - to next word,
       CTRL+Left - to previous word,
       CTRL+Home - to the beginning of text,
       CTRL+End - to the end of text.
       CTRL+Z - UnDo
       |</pre>
       If You originally assign some (plain) text to Text property, switching "underline"
       can also change other font attributes, e.g., "bold" - if fsBold style is
       in default Font. To prevent such behavior, select entire text first (see
       SelectAll) and make assignment to RE_Font property, e.g.:
       !        RichEd1.SelectAll;
       !        RichEd1.RE_Font := RichEd1.RE_Font;
       !        RichEd1.SelLength := 0;
       |<br>
       And, some other notices about formatting. Please remember, that only True
       Type fonts can be succefully scaled and transformed to get desired effects
       (e.g., bold). By default, RichEdit uses System font face name, which can
       even have problems with fsBold style. Please remember also, that assigning
       RE_Font to RE_Font just initializying formatting attributes, making all
       those valid in entire text, but does not change font attributes. To use
       True Type font, directly assign face name You wish, e.g.:
       !        RichEd1.SelectAll;
       !        RichEd1.RE_Font := RichEd1.RE_Font;
       !        RichEd1.RE_Font.FontName := 'Arial';
       !        RichEd1.SelLength := 0;

    property RE_OverwriteMode: Boolean read REGetOverwite write RESetOverwrite;
    {* |<#richedit>
       This property allows to control insert/overwrite mode. First, to examine, if
       insert or overwrite mode is current (but it is necessary either to
       access this property, at least once, immediately after creating RichEdit
       control, or to assign event OnRE_InsOvrMode_Change to your handler).
       Second, to set desired mode programmatically - by assigning value to
       this property (You also have to initialize monitoring procedure by either
       reading RE_OverwriteMode property or assigning handler to event
       OnRE_InsOvrMode_Change immediately following RichEdit control creation). }
    property OnRE_InsOvrMode_Change: TOnEvent read fOnREInsModeChg write fOnREInsModeChg;
    {* |<#richedit>
       This event is called, whenever key INSERT is pressed in control (and for
       RichEdit, this means, that insert mode is changed). }
    property RE_DisableOverwriteChange: Boolean read fReOvrDisable write RESetOvrDisable;
    {* |<#richedit>
       It is possible to disable switching between "insert" and "overwrite" mode
       by user (therefore, event OnRE_InsOvrMode_Change continue works, but it
       just called when key INSERT is pressed, though RE_OverwriteMode property
       is not actually changed if switching is disabled). }

    {* |<#richedit>
       Use this method rather then assignment to RE_Text property, if
       source is stored in file or stream (to minimize resources during
       loading of RichEdit content). Data is loading starting from current
       position in stream and no more then Length bytes are loaded (use -1
       value to load to the end of stream). Loaded data replaces entire
       content of RichEdit control, or selection only, depending on SelectionOnly
       flag.
       |<br>&nbsp;&nbsp;&nbsp;
       If You want to provide progress (e.g. in form of progress bar), assign
       OnProgress event to your handler - and to examine current position of
       loading, read TSream.Position property of soiurce stream). }
    function RE_SaveToStream( Stream: PStream; Format: TRETextFormat; SelectionOnly: Boolean ): Boolean;
    {* |<#richedit>
       Use this method rather then RE_TextProperty to store data to file
       or stream (to minimize resources during saving of RichEdit content).
       Data is saving starting from current position in a stream (until
       end of RichEdit data). If SelectionOnly flag is True, only selected
       part of RichEdit text is saved.
       |<br>&nbsp;&nbsp;&nbsp;
       Like for RE_LoadFromStream, it is possible to assign your method to
       OnProgress event (but to calculate progress of save-to-stream operation,
       compare current stream position with RE_Size[ rsBytes ] property
       value). }

    property OnProgress: TOnEvent read fOnProgress write fOnProgress;

       This event is called during RE_SaveToStream, RE_LoadFromStream (and also
       during RE_SaveToFile, RE_LoadFromFile and while accessing or changing
       RE_Text property). To calculate relative progress, it is possible to
       examine current position in stream/file with its total size while reading,
       or with rich edit text size, while writing (property RE_TextSize[ rsBytes ]).

       This property allows to get / replace content of RichEdit control
       (entire text or selection only). Using different formats, it is
       possible to exclude or replace undesired formatting information
       (see TRETextFormat specification). To get or replace entire text
       in reText mode (plain text only), it is possible to use habitual
       for edit controls Text property.
       |<br>&nbsp;&nbsp;&nbsp;
       Note: it is possible to append text to the end of RichEdit control
       using method Add, but only if property RE_Text is accessed at least
       once:

         Options: TBitBtnOptions; Layout: TGlyphLayout; GlyphBitmap: HBitmap; GlyphCount: Integer ): PControl;
{* |<#control>
   Creates image button (actually implemented as owner-drawn). In Options,
   it is possible to determine, whether bitmap or image list used to contain
   one or more (up to 5) images, correspondent to certain BitBtn state.
   |<br>&nbsp;&nbsp;&nbsp;
   For case of imagelist (option bboImageList), it is possible to use a
   number of glyphs from the image list, starting from image index given
   by GlyphCount parameter. Number of used glyphs is passed in that case
   in high word of GlyphCount parameter (if 0, one image is used therefore).
   For bboImageList, BitBtn can be Transparent (and in that case bboNoBorder
   style can be useful to draw custom buttons of non-rectangular shape).
   |<br>&nbsp;&nbsp;&nbsp;
   For case of bitmap BitBtn, image is stretched down (if too big), but can
   not be transparent. It is not necessary for bitmap BitBtn to pass correct
   GlyphCount - it is calculated on base of bitmap size, if 0 is passed.
   |<br>&nbsp;&nbsp;&nbsp;
   And, certainly, BitBtn can be without glyph image (text only). For that
   case, it is therefore is more flexible and power than usual Button (but
   requires more code). E.g., BitBtn can change its <D Font>, <D Color>,
   and to be totally <D Transparent>.
   Moreover, BitBtn can be <D Flat>, bboFixed, <D SpeedButton> and
   have property <D RepeatInterval>.
   |<br>&nbsp;&nbsp;&nbsp;
   Note: if You use bboFixed Style, use OnChange event instead of OnClick,
   because <D Checked> state is changed immediately however OnClick occure
   only when mouse or space key released (and can be not called at all if
   mouse button is released out of BitBtn bounds). Also, bboFixed defines
   only which glyph to show (the border if it is not turned off behaves as
   usual for a button, i.e. it becomes lowered and then raised again at any click).

//[NewSplitter DECLARATIONS]
function NewSplitter( AParent: PControl; MinSizePrev, MinSizeNext: Integer ): PControl;
{* |<#control>
   Creates splitter control, which will separate previous one (i.e. last
   created one before splitter on the same parent) from created
   next, allowing to user to adjust size of separated controls by dragging
   the splitter in desired direction. Created splitter becomes vertical
   or horizontal depending on Align style of previous control on the same
   parent (if caLeft/caRight then vertical, if caTop/caBottom then horizontal).
   |<br>&nbsp;&nbsp;&nbsp;
   Please note, what if previous control has no Align equal to caLeft/caRight
   or caTop/caBottom, splitter will not be able to function normally. If
   previous control does not exist, it is yet possible to use splitter as
   a resizeable panel (but set its initial Align value first - otherwise it
   is not set by default. Also, change Cursor property as You wish in that
   case, since it is not set too in case, when previous control does not
   exist).
   |<br>&nbsp;&nbsp;&nbsp;
   Additional parameters determine, which minimal size (width or height -
   correspondently to split direction) is allowed for left (top) control
   and to rest of client area of parent, correspondently. (It is possible
   later to set second control for checking its size with MinSizeNext
   value - using TControl.SecondControl property). If -1 passed,
   correspondent control size is not checked during dragging of splitter.
   Usually 0 is more suitable value (with this value, it is garantee, that
   splitter will be always available even if mouse was released far from the
   edge of form).
   |<br>&nbsp;&nbsp;&nbsp;
   It is possible for user to press Escape any time while dragging splitter
   to abort all adjustments made starting from left mouse button push and
   begin of drag the splitter. But remember please, that such event is
   controlled using timer, and therefore correspondent keyboard events
   are received by currently focused control. Be sure, that pressing Escape
   will not affect to any control on form, which could be focused, otherwise
   filter keyboard messages (by yourself) to prevent undesired handling of
   Escape key by certain controls while splitting. (Use Dragging property
   to check if splitter is dragging by user with mouse).

   is assumed to be equal to Bitmap height (if last of "squares" has
   insufficient width, it will not be used). To define fixed buttons, use
   characters '+' or '-' as a prefix for button string (even empty). To
   create groups of (radio-)buttons, use also '!' follow '+' or '-'. (These rules
   are similar used in menu creation). To define drop down button, use (as
   first) prefix '^'. (Do not forget to set <D OnTBDropDown> event for this
   case). If You want to assign images to buttons not in the same order
   how these are placed in Bitmap (or You use system bitmap), define for every
   button (in BtnImgIdxArray array) indexes for every button (excluding
   separator buttons). Otherwise, it is possible to define index only for first
   button (e.g., [0]). It is also possible to change TBImages[ ] property
   for such purpose, or do the same in method TBSetBtnImgIdx).

   Following properties, methods and event are specially designed to work with
   toolbar control:
   |#toolbar
   |<br>&nbsp;&nbsp;&nbsp;
   If your project uses Align property to align controls, this can conflict with
   toolbar native aligning. To solve such problem, place toolbar to parent panel,
   which has its own Align property assigned to desired value.
   |<br>
   To create toolbar with buttons, drawn from top to bottom, instead from left
   to right, combine caLeft / caRight in Align parameter and style tboWrapable
   when create toolbar. To adjust width of vertically aligned toolbar, it is
   possible to call ResizeParentLeft for it. E.g.:

   ! P0 := NewPanel( W, esRaised ) .SetSize( 30, 0 ) .SetAlign( caLeft );
   ! //                            ^^^^^^^^^^^^^^^^^            //////
   !TB := NewToolbar( P0, caLeft, [ tboNoDivider, tboWrapable ], DWORD(-1),
   ! //                   //////                  ///////////
   !                  [ ' ', ' ', ' ', '-', ' ', ' ' ],
   !      [ STD_FILEOPEN ] ).ResizeParentRight;
   !//Note, that caLeft is *must*, and tboWrapable style too. SetSize for
   !//parent panel is not necessary, but only if ResizeParentRight is called
   !//than for Toolbar.
   |<br><br>
   One more note: if You create toolbar without text labels (passing ' ' for
   each button You add), include also option tboTextRight to fix incorrect
   sizing of buttons under Windows9x.
   |<br>
   And, certainly, if you use image lists rather then bitmap, all written
   above about Bitmap become absolutely incorrect.

     There is a known bug exist with similar invisible tray-iconized applications.
     When a menu is activated in response to tray mouse event, if there was
     not active window, belonging to the application, the menu is not disappeared
     when mouse is clicked anywhere else. This bug is occure in Windows9x/ME.
     To avoid it, activate first your form window. This last window shoud have
     status visible (but, certainly, there are no needs to place it on visible
     part of screen - change its position, so it will not be visible for user,
     if You wish).
     <br>
     Also, to make your application "invisible" but until special event is occure,
     use Applet separate from the main form, and make for both Visible := False.
     This allows for You to make your form visible any time You wish, and without
     making application button visible if You do not wish.

  {= Когда Вы делаете невидимое приложение, которое должно быть представлено
     только иконкой в трее, обеспечьте ненулевой Handle для окна, отвечающего
     за обработку сообщений. Помните, что Handle окна создается автоматически
     только в тот момент, когда оно должно появиться в первый раз. Если свойство
     окна Visible установлено в FALSE, необходимо вызвать CreateWindow самостоятельно.
     <br>
     Существует известный BUG с подобными невидимыми минимизированными в трей
     приложениями. Когда в ответ на событие мыши активизирвано выпадающее меню,
     оно не исчезает по щелчку мыши вне этого меню. Происходит это в Windows9x/ME.
     чтобы решить эту проблему, сначала активизируйте свое окно (форму). Это окно
     должно быть видимым (но, конечно, его можно разместить вне пределов видимой
     части экрана, так что пользователю его видно не будет).
     <br>
     Так же, чтобы сделать приложение невидимым, по крайней мере, пока это не
     потребуется, используйте отдельный представитель класса TControl - глобальную
     переменную Applet, и присвойте FALSE ее свойству Visible.

  <R Data sorting (quicksort implementation)>
  This part contains implementation of 'quick sort' algorithm,
   based on following code:

|<pre>
| TQSort by Mike Junkin 10/19/95.
| DoQSort routine adapted from Peter Szymiczek's QSort procedure which
| was presented in issue#8 of The Unofficial Delphi Newsletter.

| TQSort changed by Vladimir Kladov (Mr.Bonanzas) to allow 32-bit
| sorting (of big arrays with more than 64K elements).
|</pre>

  Finally, this sort procedure is adapted to XCL (and then to KOL)
  requirements (no references to SysUtils, Classes etc. TQSort object
  is transferred to a single procedure call and DoQSort method is
  renamed to SortData - which is a regular procedure now). }

     This event handler must return -1 or +1 (correspondently for cases e1<e2
     and e2>e2). Items are enumerated from 0 to uNElem. }
  TSwapEvent = procedure (const Data : Pointer; const e1,e2 : Dword);
  {* Event type to define swap procedure which is swapping two elements of an
     array. }

//[SortData FUNCTIONS DECLARATIONS]

{* Call it to sort any array of data of any kind, passing total
   number of items in an array and two defined (regular) function
   and procedure to perform custom compare and swap operations.
   First procedure parameter is to pass it to callback function

   menus as children of any other control, not form itself.
   When Menu is created, pass FirstCmd integer value to set it
   as ID of first menu item (all other ID's obtained by incrementing this value),
   and Template, which is an array of PChar (usually array of string constants),
   containing list of menu item identifiers and/or formatting characters.

  FirstCmd value is assigned to first menu item created as its ID,
  all follow menu items are assigned to ID's obtained from FirstCmd incrementing
  it by 1. It is desirable to provide not intersected ranges of ID's for
  defferent menus in the applet.
|<br>&nbsp;&nbsp;&nbsp;
  Following formatting characters can be used in menu template strings:
|&L=<br><b>%1</b>
  <L &amp; (in identifier)> - to underline next character and use it as a shortcut character

  <L + (in front of identifier)> - to make item checked. If also

  <L - (separate)> - separator (between two items);
  <L ( (separate)> - start of submenu;
  <L ) (separate)> - end of submenu;

  To get access to menu items, use constants 0, 1, etc. It is a good idea

   This part of the unit modified by Tim Slusher and Vladimir Kladov.
}

{* Set of utility methods to work with files
   and reqistry.
   When programming KOL, which is Windows API-oriented, You should
   avoid alien (for Windows) embedded Pascal files handling, and
   use API-calls which implemented very well. This set of functions
   is intended to make this easier.
   Also TDirList object implementation present here and some registry
   access functions, which allow to make code more elegant.

   use constructing functions NewReadFileStream and NewWriteFileStream
   to work with file streams, which do not require both types of operation. }

{* To create new type of stream, define your own methods, and in your
