*mac osx updates, some more fixes for dialog code and for command button peer functionality
*
*Revision 1.2.2.7  2004/09/21 23:41:23  ddiego
*made some big changes to how the base list, tree, text, table, and tab models are laid out. They are not just plain interfaces. The actual
*concrete implementations of them now derive from BOTH Model and the specific
*tree, table, etc model interface.
*Also made some fixes to the way the text input is handled for a text control.
*We now process on a character by character basis and modify the model one
*character at a time. Previously we were just using brute force and setting
*the whole models text. This is more efficent, though its also more complex.

*
*Revision 1.1.2.5  2004/07/14 21:54:41  ddiego

*
*Revision 1.59  2004/01/20 01:54:56  ddiego
*merged some more changes from dev branch, primarily changes to
*teh RTTI API so that we now process enum sets correctly (i.e. a long
*that is a mask made of enum values).

*
*Revision 1.57.2.4  2004/03/01 05:59:19  ddiego
*and even MORE updates to the TableControl. Most of the core functionality
from Chris Maunder's CGridCtrl has been migrated over, and is functional.
Item editing and item dragging is still not done. Had to make a minor change
to the AbstractScroallable class to allow it have vertical and/or horizontal
delegate's set in order to notify them of position changes. This was needed
by the TableControl to properly update the top left non fixed cell calculation.
The performance is kind of slow ( :) ) in debug mode, but quite snappy in release.

*Revision 1.57.2.3  2004/01/18 04:52:46  ddiego
*Added a new EnumSet class that handles manipulating unsigned longs

*property is correctly read and written
*

*the values of the component state can be OR'd together.
*
*Revision 1.57.2.1  2004/01/15 05:35:04  ddiego

*"copy" toolbar item) and have tehm respond to update and actions via a
*single source.

*changes to ensure that the destroy() is properly called.
*Destructors were moved back to pbulic scope in case that was causing a bug.
*Moving them all(all teh component derived classes) to private scope causes
*a complete failure in hte VC6 compiler. Alas...
*So destructors are present, and modal dialogs can still be created on the
*stack, but almost any other component should be created on the heap, and
*gotten rid of via free() NOT using operator delete directly.
*also moved the vcs info to the end of the file for some of the headers
*This will be an ongoing process.
