+ @type:
+ class
+ @short:
+ Provides a popup menu.
+ @inherits:
+ [class]object[/class]
+ [class]widget[/class]
+ @description:
+ This widget can be used to display a popup menu.Technically, a popup menu consists of a list of menu items.[br]
+ You add items with insertItem(). An item is either a string. In addition, items can have an optional icon drawn on the very left side.[br]
+ @functions:
+ !fn: $insertItem(<text:string>,[icon_id:string])
+ Inserts menu items into a popup menu with optional icon and return the popup identifier.
+ !fn: $insertWidget(<widget:object>)[br]
+ Inserts widget items int a popup menu and return the popup identifier.[br]
+ The widget is treats as a separator; this means that the item is not selectable and you can, for example, simply insert a label if you need a popup menu with a title.
+ !fn: $insertHandle(<text_label:string>,<popupmenu:object>,[icon])
+ Inserts a submenu with optional icon into the popup menu.
+ !fn: $exec([<widget:objects>,<x:uinteger>,<y:integer>])
+ If called without paramaters show the popup menu at the current pointer position.[br]
+ With the optional parameters show the popup menu at the coordinate x,y widget parameter relative.
+ !fn: $removeItem(<popup_id:Uinteger>)
+ Removes the menu item that has the identifier id.
+ !fn: $removeItemAt(<index:uinteger>)
+ Removes the menu item at position index.
+ !fn: $insertSeparator(<index:uinteger>)
+ Inserts a separator at position index.[br]
+ If the index is negative the separator becomes the last menu item.
+ !fn: $activatedEvent(<popup_id:uinteger>)
+ This function is called when a menu item and return the the item id.[br]
+ The default implementation emits the [classfnc]$activated[/classfnc]() signal.
+ !fn: $highligthtedEvent(<popup_id:uinteger>)
+ This function is called when a menu item is highlighted and return the item id.[br]
+ The default implementation emits the [classfnc]$highlighted[/classfnc]() signal.
+ @signals:
+ !sg: $activated()
+ This signal is emitted by the default implementation of [classfnc]$activatedEvent[/classfnc]().
+ !sg: $highlighted()
+ This signal is emitted by the default implementation of [classfnc]$highlightedEvent[/classfnc]().
