Hi,
I'm trying to find out how I can hide/show parts of a dialog, using panels as suggested by Robin Dunn.
Below is a slightly modified version of the demo of using the layout contrainers (wxPython 2.2.5). In my modified version, the size of panel B is set to 1 / some size which is incremented whenever a button is pushed. In addition I hide the panel. By changing the size of the panel, the panel below (C) will readjust its size. I'm also hiding the panel, so that controls on the panel should not be reachable by using the tab-key.
Well, I'm trying to make the whole system repaint, however I'm not able to get that to work. If I resize the window manually between pressing a button, the correct layout will be shown.
Does anyone know how I force the repaint (guess it is quite easy).
Nikolai
