wxpython - Scrolling in a GUI Panel? -

After

Here is the general layout of my GUI:

  || Title ||||| |||||||||||||||| X | | | Words | | | Blah | | . . . . | | | | | | . | | | | BTN | |||||||||||||||||||||||||||||||  

In fact, there are two large mirrors, the one on which the shape changes, how big a window is, and the right ones which remain constant. I want to include some interactive widgets in the right panel, such as check boxes, radio buttons, etc., but the number of things I want to put in may be bigger than the size of the whole application. I think the panel wants to be scrollable in wxPython (or equivalent wxWidgets), how would I go about it? Here's my guess:

  class MyGUI (wx.Frame): def __init __ (self) wx.Frame (none, -1) main_panel = wx.panel (self, -1) Main_sizer = wx .BoxSizer (wx.HORIZONTAL) main_panel.SetSizer (main_sizer) left_panel = wx.panel (main_panel, -1) main_sizer.Add (left_panel, 1, wx.EXPAND) right_panel = wx.panel (main_panel, -1) Right_sizer = wx (Box_sizer) main_sizer.Add (right_panel, 0, wx.EXPAND) for category (100): right_sizer.Add (wx.CheckBox (right_panel, -1, "Happy Box"), 0, wx. EXPAND) right_sizer.Add (wx.Button (right_panel, -1, "go!"), 1, wx.EXPAND) right_panel.fit () main_panel.Fit () self.Layout () auto Now I know that wxPython has a nifty little panel called scroll panel, but for one reason or another reason it does not really recognize how big is the panel on the right; Which is to say, if I change the shape of the GUI, the scrollbar does not correct themselves. In fact, they are not even right in the first place. How can I say this intelligently?
