The Pie Menu component provides circular pie menus.

It is usually triggered as a context menu, and allows directional, gesture and traditional mouse click-move-click navigation. It also has support for keyboard navigation.

This Qt Solutions component is for Qt 3. For Qt 4 Solutions, please visit the Qt 4 Solutions Catalog.
