I've created a splitterwindow, with a treectrl panel in the first window. The panel doesn't fill up the entire window using wx.DefaultSize, and refuses to do otherwise. I tried simply setting it to the size of the parent, but GetSize() returns zero! Is that a bug? How can there be a visible window with zero size?
How can you make a panel fill up a window?
I'd appreciate any help. Below is my code.
