I have a wxPanel. How can I make it resizable by the user? With a drag-and-drop resize bar?
I wonder what the widgets I need are.
Thank you.
A Panel floating all by itself?  Doesn't sound too likely!  It would be a lot easier to answer this question if you described in more detail what you are doing, and what is not working as you expect.
In general, panels are created as children of a frame.  If the panel is the ONLY child of the frame, then it will be resized automatically along with the frame.  Otherwise you will have to handle the resize event yourself.
What have you tried so far?
