#ifndef _KPOPUP_H #define _KPOPUP_H #include <qpopupmenu.h> /// Popup menus with a title bar /** Here's a popup menu widget for KDE apps. It differs from Qt popup menu in that it has a title -- thus it is *not* to be used in a menu bar. Only two new methods are added -- setTitle(char *) and title() and a new constructor, taking the title as a first argument. The main API difference from Qt's QPopupMenu is that you should *not* expect the first item you insert into KPopupMenu to have index (an ID) 0! So the following is wrong: <pre> KPopupMenu menu("Window operations"); menu->insertItem("Move"); menu->insertItem("Minimize"); menu->insertItem("Close"); menu->connectItem(0, this, SLOT(moveWindow())); // WRONG!!! menu->connectItem(1, this, SLOT(minimizeWindow())); // WRONG!!! menu->connectItem(2, this, SLOT(closeWindow())); // WRONG!!! </pre> The reason is that the title and a double line (actually, two separators) are stored as menu items too, so the first item you insert has index 3. There's a constant KPM_FirstItem so use one of those approaches instead of the above: <pre> [1] int move_item = menu->insertItem("Move"); ... menu->connectItem(menu_item, this, SLOT(moveWindow())); [2] menu->insertItem("Move"); ... menu->connectItem(KPM_FirstItem+0, this, SLOT(moveWindow())); [3] The best one! menu->insertItem("Move", this, SLOT(moveWindow())); </pre> * @short Popup menu with title. * @version $Id: kpopmenu.h,v 1.3 1998/09/01 20:22:05 kulow Exp $ */ class KPopupMenu : public QPopupMenu { Q_OBJECT public: KPopupMenu(QWidget *parent=0, const char *name=0); KPopupMenu(const char *title, QWidget *parent=0, const char *name=0); ~KPopupMenu(); void setTitle(const char *); const char *title() const; private: void paintCell(QPainter *, int, int); void initialize(const char *); }; const int KPM_FirstItem = 3; #endif
