Hi,
I am facing an extremely annoying problem that I hope some brainy
individual could help me sort out.
I have an app with an NSView subclass, call it oldView.
This NSView has a method addView that adds a view in the first view.
In exact addView adds an NSView of a subclass, say newView. In
oldView I have implemented mouse functionality that makes it possible
for me to drag my added newViews around.
Now, everything works dandy as long as I do not add any UI elements
to my newView´s. Adding any UI elements, like buttons, scrollviews or
even nib elements make my views behave peculiar. Dragging the views
around leaves a shadow of the UI element in oldView (only UI
elements, not the rest of the view). This of course is sorted out by
a setNeedsDisplay in my oldView or by setting a solid background, but
it is somewhat annoying. What is worse is that the UI elements may
show through my newViews if they overlap!
I have tried various methods to solve this problem, but I am lost. I
have a few workarounds that may work, but I am curious about whether
others have faced the same problem and hopefully solved it?
With regards,
