I’m having a problem with wx.Gridsizer. The posted code creates a nested series of controls. The puzzle is a 3x3 grid of panes where each pane is a 3x3 grid of tiles and each tile is a 3x3 grid of buttons. I want to set the parameters for the outer two gridsizers so that each pane and each tile is evenly separated from the other panes and tiles. As such, I created the two lists, RPAD and CPAD (indexed by 0-relative row and column numbers). If you run the code and compare the displayed GUI and the printed output you’ll see that they seem to be at odds. You’ll see that there is a wider border between rows 1 & 2, and columns 1 and 2. Take panes 1 & 2. The given values are
Pane(1) padding is wx.TOP
Pane(2) padding is wx.TOP wx.RIGHT
The GUI, however, has extra padding added either to the right of pane 1 or the left of pane 2. If I am misinterpreting the use of borders and padding could you please explain what I am doing incorrectly?
