QDockWidget Class Reference
^{[QtGui module]}

Appearance

A QDockWidget consists of a title bar and the content area. The titlebar displays the dock widgets window title, a float button and a close button. Depending on the state of the QDockWidget, the float and close buttons may be either disabled or not shown at all.

The visual appearance of the title bar and buttons is dependent on the style in use.
