 * @brief Demo program for the PieMenuQt widget
 *
 * The pie menu is fully customizable for arbitrary amounts of buttons,
 * disabled buttons, button icons and appearance parameters.
 * All button clicks are published as a Qt signal containing the
 * clicked button's index.
 *
 * When the pin/unpin button is activated, the pie menu can be pinned
 * to keep it open until it is manually or programmatically closed.
