File: IconDBCallbacks.c
Abstract: Data browser control callback functions for a list of icons with text
labels.
Version: 7.0
Change History:
<7.0> removed all code specific to PEF
removed all code specific to Mac OS X prior to 10.3
<6.0> added support for Quartz 2D/Core Graphics
split the callbacks into different versions based on
what's available in each system version
added calculateCGDrawingBounds and getClipCGRect for the
Mach-O version
<5.0> changed this file's name from IconListDef.c to
IconDBCallbacks.c
converted everything from a List Definition to a Data
Browser draw item callback
added a Data Browser item notification callback to
handle item selection and deselection
<4.0> removed all Classic code
<3.0> no changes necessary
<2.0> Carbonized
added accessor functions for the Classic version (see
the comment below)
<1.0> first release version
