*Revision 1.2.2.1  2003/03/12 03:12:45  ddiego
*switched all member variable that used the "m_"<name> prefix to
* <name>"_" suffix nameing standard.
*Also changed all vcf builder files to accomadate this.
*Changes were made to the Stream classes to NOT multiple inheritance and to
*be a little more correct. Changes include breaking the FileStream into two
*distinct classes, one for input and one for output.
*
*Revision 1.2  2003/02/26 04:30:52  ddiego
*merge of code in the devmain-0-5-9 branch into the current tree.
*most additions are in the area of the current linux port, but the major

*still under development) and the change over to using the Delegate class
*exclusively from the older event handler macros.
*
*Revision 1.1.2.4  2003/02/03 05:22:54  ddiego
*added support for command types to the PuchButton class
*added support for clicks in the PuchButton class to auto close a dialog
*if it is parented to one, similar to the CommandButton. This is part of the
*gradual phase out of the CommandButton class
*Add supprt for drawing a focus rect in the PushButton class
*plugged in tabbing bahaviour to the X11UIToolkit. It seems as though
*"Shift" + "Tab" is not being picked up properly
*Finished implementing the X11Dialog::showMessage(String,String) method
*and also add some finishing touches to teh X11Dialog so it displays correctly
*Add some finishing touches to the X11UIToolkit::runModalEventLoop() as well
*
*Revision 1.1.2.3  2003/01/19 03:11:59  ddiego
*misc coding fixes, added x11 error handler
*
*Revision 1.1.2.2  2003/01/16 04:46:53  ddiego
*added support for default X11 cursors
*added support for translating coordinates from screen to client
*and client to screen, where  the screen is the RootWindow
*
*Revision 1.1.2.1  2002/12/26 04:32:12  ddiego
*added basic peer implementation to ApplicationKit so that we can now create
*a VERY simple application and terminate correctly. Woohoo! First steps
*of running on linux!
