QDockWidget without a title bar

Question

I want to delete the title bar of QDockWidget completely. Is there any method to do this except the stylesheet?

Answer 1

dockWidget->setTitleBarWidget(new QWidget());

Answer 2

To disable window decorations (title) you have to set several flags in widget constructor, like this:

drawer::drawer(QWidget *parent) :
    QDockWidget(parent, Qt::Window | Qt::WindowStaysOnTopHint |
        Qt::X11BypassWindowManagerHint | Qt::FramelessWindowHint) /**/
{}

This disabled title and removes window from taskbar. For more information use Window Flags
