How to add canvases to a sizer and refresh the parent frame?

[Jory R Ferrell]

I am using wxPython. I need to be able to add and remove panels/canvases on demand, but I don't know how to refresh the entire parent frame (the base starting window). I tried fooling with the Full_Repaint option, but got no where. The method I am using, to add and (hopefully) refresh the frame, Add_Canvas(), starts at line 50.

canvas_List = [Cone_Canvas, CubeCanvas]
 
class MainWindow(wx.Frame):
    def __init__(self, parent = None, id = -1, title = "PyOpenGL Example 1"):
        # Init
        wx.Frame.__init__(
                self, parent, id, title, size = (400,200),
                style = wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE
        )
 
        # TextCtrl
        # self.control = wx.TextCtrl(self, -1, style = wx.TE_MULTILINE)
 
        #self.control = ConeCanvas(self)
 
        box = wx.BoxSizer(wx.HORIZONTAL)
 
    for canvas in canvas_List:
        box.Add(canvas(self), 1, wx.EXPAND)
 
 
        self.SetAutoLayout(True)
        self.SetSizer(box)
        self.Layout()
 
        # StatusBar
        self.CreateStatusBar()
 
        # Filemenu
        filemenu = wx.Menu()
 
        # Filemenu - About
        menuitem = filemenu.Append(-1, "Add Canvas", "Add a Canvas")
        self.Bind(wx.EVT_MENU, self.Add_Canvas, menuitem) # here comes the event-handler
        # Filemenu - Separator
        filemenu.AppendSeparator()
 
        # Filemenu - Exit
        menuitem = filemenu.Append(-1, "E&xit", "Terminate the program")
        self.Bind(wx.EVT_MENU, self.OnExit, menuitem) # here comes the event-handler
 
        # Menubar
        menubar = wx.MenuBar()
        menubar.Append(filemenu,"&File")
        self.SetMenuBar(menubar)
 
        # Show
        self.Show(True)
 
#!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!#
 
    # What do I call(or can I call anything at all?) to
    #    repaint the entire frame? 
 
    def Add_Canvas(self,event):
        canvas_List.append(Cube_Canvas)
        Repaint_Frame() # <---- pseudo....
 
#!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!#
 
    def OnExit(self,event):
        self.Close(True)  # Close the frame.

I do not use Wx but know that it does have a Refresh() function. Try Google for more info.

I already tried it. Nothing happened.

Nevermind....it was a namespace conflict. I had to rename the sizer, dubbed 'box', as 'self.box'. The window was refreshing without problem, but since nothing was actually being appended to the sizer, there was no visible result to confirm the update of the window and I assumed it wasn't occurring. :P But yeh...it does work. Thanks.
