When the user presses the menubutton's pushbutton, the menu pops up. A menu is composed of menu items each of which has a string label, and optionally an icon. The index of the item that the user's input device (e.g. stylus) is pointing at is the currentItem(), whose text is available using currentText(). Menu items are inserted with the \link MenuButton::MenuButton() constructor\endlink, insertItem() or insertItems(). Separators are inserted with insertSeparator(). All the items in the menu can be removed by calling clear(). Items can be selected programmatically using select(). When a menu item is selected (programmatically or by the user), the selected() signal is emitted. \ingroup qtopiaemb */ /*! \overload void MenuButton::selected(int index) This signal is emitted when the item at position \a index is selected. */ /*! \fn void MenuButton::selected(const QString& text) This signal is emitted when the item with the label \a text is selected. */ /*!
