With PyQgis how can I convert absolute screen coordinates (say,
123,456) into map coordinates of the
It would be no problem if I had screen coordinates relative to the
iface.mapCanvas.viewport().geometry() gives me sth like
QRect(2,2,2198, 1090) and
iface.mapCanvas().extent() gives me a
xmin,xmax,ymin,ymax, so (leaving projection issues out of the scope) the conversion would be simple.
But since the absolute position of the
mapCanvas may vary with toolbar positions or layer windows width, the question reduces to 'how to derive the absolute screen position of the map canvas?'.
