This article shows the use of QtoolBar and QtoolButton.This article is one of the basic article of QT.

Tool button is a special button that provides quick-access to specific commands or options. As opposed to a normal command button, a tool button usually doesn't show a text label, but shows an icon instead.

The QToolBar class provides a movable panel that contains a set of controls.When a toolbar is resized in such a way that it is too small to show all the items it contains, an extension button will appear as the last item in the toolbar. Pressing the extension button will pop up a menu containing the items that does not currently fit in the toolbar

QToolbar isn't supposed to be properly supported on Symbian. How does this look on a real device? Do you need to explicitly set geometry?
