How Do I Make A GUI Open With The Correct Size With WxPython?

I'm having trouble with the sizing of my window. When first opening the GUI, the initial size only shows a portion of what's in the window; its too small. Scroll bars are present

Solution 1:

Just add the size when creating the Frame:

wx.Frame.__init__(self, None, -1, 'CR Part 1', size=(800, 600))
