Adding vertical boarders

This is how my programm looks like

I want to have darker blue borders on the left and right side of the Window. Despite setting the size manually, for some reason, the top level panel "panel" is resized to the toplevelsizer size. And I don't know why. The way I achieve the other borders is by having a blue panel below the top-sizer and adding spacer between the other panels/widgets.

Solution

You don't leave any borders around the elements added to TopLevelSizer, so there are none in the left and the right directions. You could simply remove the spacers and use Add(whatever, 0, wx.EXPAND|wx.ALL, self.widthBoarder) to have the borders show through.
