用wxPython建立自銷燬皮膚的方法
The other day I saw a question on StackOverflow about how to dynamically destroy and create panels after a certain amount of time has passed. I told the fellow that he could use the examples from one of my blog articles where I destroyed and created buttons, but the dude just didn’t get it.
So I wrote a simple example where the panel displays a count down and then destroys itself and is promptly replaced with another panel.
Here’s the code for your viewing pleasure:
