Qt Main Window Example

" + + "

This is a demonstration of the QMainWindow, QToolBar and " + "QDockWidget classes.

" + + "

The tool bar and dock widgets can be dragged around and rearranged " + "using the mouse or via the menu.

" + + "

Each dock widget contains a colored frame and a context " + "(right-click) menu.

" + +#ifdef Q_OS_MAC + "

On Mac OS X, the \"Black\" dock widget has been created as a " + "Drawer, which is a special kind of QDockWidget.
