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.

static

Searches for features on the map canvas, which are located at the specified event point.

The geometryTypes argument lists acceptable geometry types.

This method searches through all layers on the canvas, attempting to find matching features at the event point.
