c9e180acac
lazarus/lcl/interfaces/gtk/gtkobject.inc
lazarus c9e180acac TPanel implemented. 
Basic graphic primitives split into GraphType package, so that we can
reference it from interface (GTK, Win32) units.
New Frame3d canvas method that uses native (themed) drawing (GTK only).
New overloaded Canvas.TextRect method.
LCLLinux and Graphics was split, so a bunch of files had to be modified.

Revision 1.103 2002/02/03 00:24:01 lazarus
TPanel implemented.
Basic graphic primitives split into GraphType package, so that we can
reference it from interface (GTK, Win32) units.
New Frame3d canvas method that uses native (themed) drawing (GTK only).
New overloaded Canvas.TextRect method.
LCLLinux and Graphics was split, so a bunch of files had to be modified.
Revision 1.102 2002/01/24 15:40:59 lazarus
MG: deactivated clipboard setting target list for win32
Revision 1.101 2002/01/08 16:02:45 lazarus
Minor changes to TListView.
Added TImageList to the IDE
Shane
Revision 1.100 2002/01/04 20:29:04 lazarus
Added images to TListView.
Shane
Revision 1.99 2002/01/03 21:17:08 lazarus
added column visible and autosize settings.
Shane
Revision 1.98 2002/01/03 15:31:27 lazarus
Added changes to propedit so the colum editor changes effect the TListView.
Shane
Revision 1.97 2002/01/01 15:50:16 lazarus
MG: fixed initial component aligning
Revision 1.96 2001/12/28 15:12:02 lazarus
MG: LM_SIZE and LM_MOVE messages are now send directly, not queued
Revision 1.95 2001/12/21 18:17:00 lazarus
Added TImage class
Shane
Revision 1.94 2001/12/20 19:11:23 lazarus
Changed the delay for the hints from 100 miliseconds to 500. I'm hoping this reduces the crashing for some people until I determine the problem.
Shane
