How to restore the background behind a drawn rectangle?

Question

Hi everyone,

In my application I need to draw several filled rectangles on a panel with a tiled background image. Depending on user actions, certain - not all - rectangles must be removed afterwards, revealing the background image again. Drawing and filling the rectangles is not so difficult, but how can I remove them in such a way that the background gets restored correctly?

Thank you,

Cooz

Answer 1

Stop drawing them.  Put the rectangles in a List(of Rectangle) and remove them when you when you don't want them drawn.  Iterate through the list in the Paint event to draw the rectangles.

Answer 2

Hi John,

Yep, that works. "Stop drawing them ... draw the rectangles." had me a little puzzled at first though.

Thanks!
