Hello everyone,
could anyone maybe help me to understand the attached Evas program. It
is a small example which changes the color of a centered rectangle with
mouse in/out.
I'm trying to understand why the mouse pointer is not being released
after a mouse click onto the rectangle with has pointer mode
EVAS_OBJECT_POINTER_MODE_NOGRAB_NO_REPEAT_UPDOWN. I would expect it to
_not_ grab the pointer.
Many thanks in advance!
Thomas
