python - How to remove all selection from all registered layers using QGIS plugin?

Friday 23 October 2015

I want to remove all selection from registered layer in QGIS using Python. I tried to clear the map canvas using:

self.iface.mapCanvas().clear()  
self.iface.mapCanvas().refresh()

but the selection persists.

Answer

There is probably a better way to do this, but you can iterate the layers in mapCanvas, and use removeSelection() method.

Something like this:

mc = self.iface.mapCanvas()


For layer in mc.layers():
    if layer.type() == layer.VectorLayer:
        layer.removeSelection()

mc.refresh()
