  Revision 1.36  1999/09/09 14:15:27  pierre
   + cmCopyWin,cmPasteWin

  Revision 1.35  1999/08/16 18:25:19  peter
    * Adjusting the selection when the editor didn't contain any line.
    * Reserved word recognition redesigned, but this didn't affect the overall
      syntax highlight speed remarkably (at least not on my Amd-K6/350).
      The syntax scanner loop is a bit slow but the main problem is the
      recognition of special symbols. Switching off symbol processing boosts
      the performance up to ca. 200%...
    * The editor didn't allow copying (for ex to clipboard) of a single character
    * 'File|Save as' caused permanently run-time error 3. Not any more now...
    * Compiler Messages window (actually the whole desktop) did not act on any
      keypress when compilation failed and thus the window remained visible
    + Message windows are now closed upon pressing Esc
    + At 'Run' the IDE checks whether any sources are modified, and recompiles
      only when neccessary
    + BlockRead and BlockWrite (Ctrl+K+R/W) implemented in TCodeEditor
    + LineSelect (Ctrl+K+L) implemented
    * The IDE had problems closing help windows before saving the desktop

  Revision 1.34  1999/08/03 20:22:32  peter
    + TTab acts now on Ctrl+Tab and Ctrl+Shift+Tab...
    + Desktop saving should work now
       - History saved
       - Clipboard content saved
       - Desktop saved
       - Symbol info saved
    * syntax-highlight bug fixed, which compared special keywords case sensitive
      (for ex. 'asm' caused asm-highlighting, while 'ASM' didn't)
    * with 'whole words only' set, the editor didn't found occourences of the
      searched text, if the text appeared previously in the same line, but didn't
      satisfied the 'whole-word' condition
    * ^QB jumped to (SelStart.X,SelEnd.X) instead of (SelStart.X,SelStart.Y)
      (ie. the beginning of the selection)
    * when started typing in a new line, but not at the start (X=0) of it,
      the editor inserted the text one character more to left as it should...
    * TCodeEditor.HideSelection (Ctrl-K+H) didn't update the screen
    * Shift shouldn't cause so much trouble in TCodeEditor now...
    * Syntax highlight had problems recognizing a special symbol if it was
      prefixed by another symbol character in the source text
    * Auto-save also occours at Dos shell, Tool execution, etc. now...

  Revision 1.33  1999/07/12 13:14:18  pierre
    * LineEnd bug corrected, now goes end of text even if selected
    + Until Return for debugger
    + Code for Quit inside GDB Window

  Revision 1.32  1999/07/10 01:24:17  pierre
   + First implementation of watches window

  Revision 1.31  1999/06/29 22:50:14  peter

   + RemoveBrowsersCollection in TIDEApp.Done

  Revision 1.28  1999/06/25 00:46:33  pierre
     + UpdateTarget to show current target
     + SearchSymbol, not scope aware (this will need a PPU change !)

  Revision 1.27  1999/05/22 13:44:30  peter

    * MenuBar didn't update itself automatically on command-set changes
    * Fixed Debugging/Profiling options dialog
    * TCodeEditor converts spaces to tabs at save only if efUseTabChars is
 set
    * efBackSpaceUnindents works correctly
    + 'Messages' window implemented
    + Added '$CAP MSG()' and '$CAP EDIT' to available tool-macros
    + Added TP message-filter support (for ex. you can call GREP thru
      GREP2MSG and view the result in the messages window - just like in TP)
    * A 'var' was missing from the param-list of THelpFacility.TopicSearch,
      so topic search didn't work...
    * In FPHELP.PAS there were still context-variables defined as word instead
      of THelpCtx
    * StdStatusKeys() was missing from the statusdef for help windows
