Hi list,
I'd like to build a custom subclass of NSImageView that is
transparent to dragging.
My custom view is used to draw borders around an NSImageView. It's
positionnned on top of the image in the view hierarchy, and draws
a PNG with alpha mask to draw the border.
The image view behind the custom view supports drag&drop, so the
user can drag an image file from the Finder and drop it into the
image frame.
However, the custom border view intercepts all drags....
For various reasons, I'd like to avoid having to build a class
that draws the border AND the image itself.
Does anybody have a solution ?
Why not just putting the NSImageView inside the custom view?
I'd like to avoid this solution as it would require me to rewrite
lots of classes to be compatible with this new embedded structures.
If possible I'd like to find out how to render the custom-view
transparent to dragging as this wouldn't break the existing logic.
