Hello...
Have you seen the Carbon HIToolbox stuff?
Based on the release notes, it would be easier to use since it
doesn't rely on Quickdraw.
http://developer.apple.com/documentation/ReleaseNotes/Carbon/HIToolbox.html
If you scroll down there is a section with the heading "Appearance
Manager" and subheading "Header files (HIToolbox): Appearance.h,
HITheme.h". If you do an command-F find for "2816257" in the text of
that page it should take you to the right place.
Hope that helps,
Louis
This didn't work; it continued to draw the button overlapped with
the menu item area. NSButtonCell's -setUsesItemFromMenu failed as
well. I finally found a Carbon Appearance API to draw the proper
button: DrawThemeButton(), with various options. Only one problem: I
can't seem to get a proper conversion from a view-local
CoreGraphics-based NSRect to the QuickDraw screen coordinates the
Appearance APIs require. I've tried various combinations of manual
mathematics, NSWindow's convertBaseToScreen, NSView's
convertRect:toView:, etc. etc., and nothing comes up quite right
without hard-coding coordinates. I've even overriden isFlipped to
return YES, without any effect that I can see. How do I convert an
NSRect specifying bottom-up coordinates in view-local coordinates to
a (QuickDraw) Rect specifying top-down screen coordinates? Or, how
do I find a Cocoa/CoreGraphics equivalent to the Appearance APIs?
