Hi Mojmir, My understanding is that qtableView uses a (private) layout to manage the qheaderview, scroll bars, etc. Unfortunately, the docs don't spell this out.
One workaround is to - set the top content margin of the viewport to the height of your button bar. (setContentMargins) - create the button bar owned by the viewport, and positioned at (0, 0). - listen for viewport resize events and adjust your button bar width. (installEventFilter) Hope that helps, Tony > Sent: Thursday, 17 April 2014 12:40 AM > > Hello, > > how to extend a qtableview with a custom button bar? so that the button > bar is above the qtableview. > > i tried something like this, but it does not feel right: > struct MyTableView : QTableView > and in the constructor do > 1) layout = new QVBoxLayout > 2) setLayout(layout) > 3) mybuttonbar = new ... > 4) layout->insertWidget(0, mybuttonbar) > > but it behaves in weird ways (endless loop in some parent detection, stealing > keypresses from qtableview)... so i am not sure that is the way to do it. > > Another possibility is to create completely different class and using > composition instead of inheritance.
