Detailed Description

The QgsMapToolAdvancedDigitizing class is a QgsMapTool whcih gives event directly in map coordinates and allows filtering its events.

Events from QgsMapTool are caught and their QMouseEvent are transformed into QgsMapMouseEvent (with map coordinates). Events are then forwarded to corresponding virtual methods which can be reimplemented in subclasses. An event filter can be set on the map tool to filter and modify the events in map coordinates (

See also
QgsMapToolMapEventFilter).
Note
at the moment, the event filter is used by the CAD tools (
See also
QgsCadDocWidget).
Note
the event filter definition is not exposed in python API to avoid any unexpected behavior.
