Hi,
I am writing a program that can dynamic display the process of bubble sort. My programme now can randomise the unsorted bars(rectangles) .But there is a problem came to me, when I start sorting, how to erase part of the rectangle and redraw them(aim to show the swap between two bars)?
Any suggestion?
Thanks,
Shannon

Erasing is simply a matter of redrawing what is under the thing to be erased. In your case probably whatever is the background color.

unless performance proves to be a problem, I'd just re-draw the entire
thing whenever there is a change.
If you want to get fancier, you may want to try wx.lib.floatcanvas,
which will give you nifty features like auto-scaling, etc. But it
looks like you're close.
