Remove margin space from QDockWidget in QMainWindow

Question

QDockWidget is giving left margin of 4px to the widget i add to the dockwidget. I tried

theToolbarDock->setStyleSheet("margin: 0px; border:0px");
theToolbarDock->setContentsMargins(0,0,0,0);

and

theToolbarDock->layout()->setContentsMargins(0,0,0,0);

But in vain. It still persist with 4px left margin i have to remove from the QDockWidget. the dock widget is in RightDockWidgetArea

Answer 1

This worked for me:

QMainWindow::separator {
    width: 10px;
    height: 0px;
    margin: -10px;
    padding: 0px;
}

Let me know if it's what you need.

Answer 2

setContentsMargins is applicable to the layout only.. not the widget.

Try setting it on the layout your dockwidget instead.
