Detailed Description

The QgsIdentifyMenu class builds a menu to be used with identify results (.

See also: QgsMapToolIdentify). It is customizable and can display attribute actions (; QgsAction) as well as map layer actions (; QgsMapLayerAction). It can also embed custom map layer actions, defined for this menu exclusively. If used in a QgsMapToolIdentify, it is accessible via QgsMapToolIdentify::identifyMenu() and can be customized in the map tool sub-class.
