Detailed Description
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:
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!!!
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:
[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()));
