Question

Here is the link to the code I found on the web (embedding matplotlib in wxpython):

My question is does anybody know why menubar appears with some delay? And is there a way how to get rid of this delay?

Thanks!

Answer 1

Reading the code, the problem might be that self.draw_figure() is the culprit here. wx needs to render the frame, but can only do that as soon as the main thread (running wx) is cleared. My guess is that self.draw_figure() is a computation-heavy method call and blocks the drawing of the menubar. Try using wx.CallAfter(self.draw_figure), to free up the thread. After all other rendering has finished, the figure will be drawn.

_{PS: I do not have wx 2.8 installed (required for matplotlib), so I cannot verify if this is completely valid.}
