I'm trying to get the mouse position whenever the user clicks the canvas
when using a map tool. I've tried this and it works but only with
custom map tools, not with defaults like: Select features, Add feature,
etc...
This is the script to print in the console the QgsMapMouseEvent.
canvas = iface.mapCanvas()
new_tool = canvas.mapTool()
canvas.unsetMapTool(new_tool)
old_function = new_tool.canvasPressEvent
def canvasPressEvent(mouse):
old_function(mouse)
print(mouse)
new_tool.canvasPressEvent = canvasPressEvent
canvas.setMapTool(new_tool)
Is it possible to override functions like canvasMoveEvent
<https://qgis.org/pyqgis/3.22/gui/QgsMapTool.html#qgis.gui.QgsMapTool.canvasMoveEvent>
, canvasPressEvent
<https://qgis.org/pyqgis/3.22/gui/QgsMapTool.html#qgis.gui.QgsMapTool.canvasPressEvent>
on
default tools?
