[QGIS-Developer] Disabling map context menu via PyQGIS

[Benjamin Jakimow]

Hi Hannes,

in C++ you could override
void QgsMapCanvas::showContextMenu( QgsMapMouseEvent *event )

which creates and shows the context menu.

in Python showContextMenu is not available. There you could re-implement
void QgsMapCanvas::mousePressEvent( QMouseEvent *e ) to avoid any calls 
of showContextMenu()

If you just like to modify the context menu, you might add a slot for the
void contextMenuAboutToShow( QMenu *menu, QgsMapMouseEvent *event ) 
signal that manipulates the menu.

Greetings,

Benjamin


So you might either override it or

to disable the context menu you can override QgsMapCanvas::mousePressEvent
