[QGIS-Developer] Temporarily disable map canvas right click showing Copy Coordinates

[Jacky Volpes]

Maybe return True in your eventFilter, so that the event is not 
processed further by other widgets?

I don’t want the user to see this.  I want my mouse click event to be recognized and not have QGIS use it to popup the Copy Coordinates.  Is there a way to call QgsMapTool.deactivate on that built in tool just for this instance and then reactivate it?
