In UpdateFields, I show/hide a lot of controls, with the intention that certain rows of grid are hidden. However, even when the controls are hidden, the GridBagSizer acts as if they still need space, so the dialog becomes full of gaps (see pictures). How can I resolve this?
Also, there's a gap below the bottom button. Any idea what that's about?
Solution
You can use grid.SetEmptyCellSize((0,0)) to reduce the gap when some item is hidden.
And use self.Fit to fit the frame.
