Merely by telling my window's contentView to setWantsLayer: YES,
the text
fields in that window are no longer drawing their focus ring
correctly (a
thin blue line appears inside the field, but the thick blue line
outside the
field is no longer drawn). What can I do about this? Thx - m.
Similarly, NSPathControl does not draw correctly when layers are on.
And other views too. :( After seeing that merely flipping this BOOL
caused so many problems, I decided to wait until 10.5.x before
playing
with it more.
Besides seeing the focus ring problem, too, I have one more effect
to contribute: I gave a view inside a split view the wantsLayer
attribute. This view in turn contains a table view, which is resized
together with its container view. Now while resizing the pane with
the mouse, the table view starts to flicker during redraw. That is,
it draws its background, makes that visible, then draws the content
text for each move of the mouse.
The split view is custom made, so it is possible that the problem
does not happen with NSSplitView, but I doubt it. All I do is
calling [pane setFrame].
Lets hope for 10.5.x (x > 1)
To add to this, I've used setWantsLayer: (toggled in IB) for a little
container view which contains some buttons. Sometimes for no apparent
reason, some of the buttons would show up and the others wouldnt. It
would change from day to day. It seems a little buggy to say the least._______________________________________________
