Bug report #12245

iface.mapCanvas().refreshMap() segfaults QGIS

Crashes QGIS or corrupts data:Yes Copied to github as #:20430


Needed to refresh my mapcanvas for a plugin, and refresh() did not do the job, so I found refreshMap()...

That just crashes QGIS here, running master on Debian.
I see it is a private slot, and tried other slots.

Not sure if this can be handled more gently, or it is just a fact of life: you should not call private slots in pyqgis....

  • Resolution set to invalid
  • Status changed from Open to Closed

refreshMap() is private because it is not meant to be used from outside... It deliberately crashes on an assertion condition. It is not a part of API, the fact you can call it is just something resulting from PyQt's new signals/slots mechanism.
