Hello to all.
I would like to add splitter bar in mainwindow.
In image attached I would like to add splitter bar and then when user click on it they can up or down de display.
In the designer you do that by adding 2 widgets, select them both and then right click and select lay out -> lay out h/v in splitter. Note that the two widgets can't be already in a layout, so you might need to break the layout first.
