I have a bunch of standard qt creator dragged-on controls, which I have at the bottom of a window. I have one table widget that I want to expand vertically to be able to display more rows if the window is expanded downwards, less if upwards to a minimum. I want all the other widgets to stick to the bottom of the window as that edge moves. I'm using Qt Creator 2.1.0 and Qt 4.7, and I don't see any flags for the widgets that would do what I need, nor did googling really turn up anything enlightening. Perhaps it has something to do with putting the widgets in a container that moves and/or stretches? Right now, they're just on MainWindow.
Just set a vertical layout, add a spacer to it, and then your widget. The spacer will push your widget all the way down. Additionally you might want to toy around with the size policies.
