Functions
`$insertItem(<text:string>,[icon_id:string])`
Inserts menu items into a popup menu with optional icon and return the popup identifier.
`$addMenu(<popupmenu:hobject,[idx:uinteger])`
Add a popupmenu. With the optional parameter idx the popup will be inserted.
`$setTitle(<text:string>)`
Sets the popupmenu title to text.
`$exec([<widget:objects>,<x:uinteger>,<y:integer>])`
If called without parameters show the popup menu at the current pointer position. With the optional parameters show the popup menu at the coordinate x,y widget parameter relative.
`$removeItem(<popup_id:Uinteger>)`
Removes the menu item that has the identifier ID.
`$removeItemAt(<index:uinteger>)`
Removes the menu item at position index.
`$insertSeparator(<index:uinteger>)`
Inserts a separator at position index. If the index is negative the separator becomes the last menu item.
`$activatedEvent(<popup_id:uinteger>)`
This function is called when a menu item and return the the item ID. The default implementation emits the $activated() signal.
`$highligthtedEvent(<popup_id:uinteger>)`
This function is called when a menu item is highlighted (hovered) and return the item ID. The default implementation emits the $highlighted() signal.
Signals
`$activated()`
This signal is emitted by the default implementation of $activatedEvent().
`$highlighted()`
This signal is emitted by the default implementation of $highlightedEvent().
