Hi David,
Thanks for the response. Unfortunately doing the hide/remove/show
doesn't change things at all. I still get crud/turds/artifacts!
Code:
SetControlVisibility(controlRef, false, true);
SetControl32BitMaximum(controlRef, 2); // was 3
SetControlVisibility(controlRef, true, true);
The tab control I'm modifying is embedded inside a user pane which is
actually inside another user pane which is inside a tab. Are there
settings that I need to adjust for the user panes (or events to
handle) that would help?

I have a Tab control that I am adding to and removing tabs from
dynamically. I'm seeing the issue on OS X 10.2.8 in a
non-compositing window, where, after removing a tab, the tab control
redraws itself, but doesn't completely erase all of the old tab
graphics. That is, there's artifacts left on the screen to the left
and right of the new tabs.
In the particular case I'm dealing with, the dynamic tab is embedded
inside another tab control. By calling:
ControlRef controlRef;
::GetSuperControl(tabControlRef, &controlRef); // Get to tab
contents container control
::GetSuperControl(controlRef, &controlRef); // Get to tab
item control
::GetSuperControl(controlRef, &controlRef); // Get to tab
control
::Draw1Control(controlRef);
Of course, the dynamic tab control could be just in a window in
which there isn't this guaranteed hierarchy. It could also be in a
compositing window. What is the easiest and best way to trigger a
redraw of this screen space?
I don't know if it will work, but I'd be inclined to try hiding the
tab control, add/remove a tab, show the tab control. Does that
eliminate the artifacts?
Incidentally, the highly technical term that is often used around
here for "artifacts" is "turds". Matt likes "crud".
