Hi Dmitry, Mike.
A few notes:
- After the fix we cannot control composite over background(see
CompositeTest.java), it works on windows and on macosx on jdk6.
- Graphics.getBackground() now returns transparent color so clearRect,
paintAll(Graphics g) etc will work differently.
I have a few questions about these changes.
- Is it possible to replace composite from src_over to src between layer
and nswindow? I think shadow will be fixed automatically if we change
composite to src, because in this case we don`t need to set nswindow
background to clearColor.
- If we set background of the window to clearcolor and paint something
in drawRect, we will get correct shadow, but the shadow disappear if we
paint the same things using layer. Why? Is it possible to make the same
window using layers?
Note: It has shadow and transparent to mouse clicks.
