  Revision 1.3  2000/08/10 10:55:45  lazarus
  Changed TCustomDialog to TCommonDialog
  Shane

  Revision 1.2  2000/08/09 18:32:10  lazarus
  Added more code for the find function.
  Shane

  Revision 1.1  2000/07/13 10:28:23  michael
  + Initial import

  Revision 1.10  2000/02/28 19:16:04  lazarus
  Added code to the FILE CLOSE to check if the file was modified.  HAven't gotten the application.messagebox working yet though.  It won't stay visible.
  Shane

  Revision 1.9  2000/02/22 22:19:49  lazarus
  TCustomDialog is a descendant of TComponent.
  Initial cuts a form's proper Close behaviour.

  Revision 1.8  2000/02/22 17:32:49  lazarus
  Modified the ShowModal call.
  For TCustomForm is simply sets the visible to true now and adds fsModal to FFormState.  In gtkObject.inc FFormState is checked.  If it contains fsModal then either gtk_grab_add or gtk_grab_remove is called depending on the value of VISIBLE.

  The same goes for TCustomDialog (open, save, font, color).
  I moved the Execute out of the individual dialogs and moved it into TCustomDialog and made it virtual because FONT needs to set some stuff before calling the inherited execute.
  Shane

  Revision 1.7  1999/12/10 00:47:01  lazarus
  MWE:
    Fixed some samples
    Fixed Dialog parent is no longer needed

  Shane Aug 16th 1999  14:07 CST

  Revision 1.4  1999/07/31 06:39:21  lazarus

       Modified the IntSendMessage3 to include a data variable. It isn't used
       yet but will help in merging the Message2 and Message3 features.

       Adjusted TColor routines to match Delphi color format

       Added a TGdkColorToTColor routine in gtkproc.inc

       Finished the TColorDialog added to comDialog example.        MAH
