Fixed bug #719
Mike Blaguszewski 2009-03-23 13:32:22 PDT
Patch to 1.2 HEAD that fixes the issue
Fixes bug in SDL 1.2.13 where clicking on an app's title bar to activate the
app, when cursor capturing is enabled, will cause the window to jump. This is
because SDL's handler for activate events calls a low-level Quartz function to
move the cursor. Calling this when the mouse is down in the title bar confuses
the WindowServer into thinking the title bar has been dragged. The patch defers
processing of activate events in this case.
The bottom line is that CGWarpMouseCursorPosition() is not safe to call when
the mouse in down in a window's title bar.
