I have used layouts for everything.
There is the main window with a splitter inserted via layout.
And then there are two other layouts, containing some widgets.
I hoped this would place the splitter control in a way that the small tabbasic is completely visible without giving it more place than needed and leaving the rest for ErgebnisGrid.
But this doesn't work.
I finally came up with some sort of solution by setting the position like this:
This works fine. But if you minimize the app and then maximize it again, it's all painted black. Trying TopWindow::Layout(); or anything else doesn't help..
Any ideas? Is there something rather obvious that I am missing?
