Where is the QGIS API action for "deselect"?

Question

Where is the QGIS action for the “deselect” toolbutton in the 'Attributes" toolbar? I do not see this action in the QgisInterface class or do not recognize it by name. Is it missing from iface?

I'd like to use this action in a plugin directly instead of the button on the toolbar.

I believe the Deselect function is from the QgsVectorLayer class. — Joseph, Jul 24 '15 at 13:48
Yes, That is probably what I mean. The toolbar turns on/off with 'Attributes' in the View/Toolbars menu item and the tooltip is "Deselect Features from all Layers'. In any case, I do not see it in iface. — Worth Lutz, Jul 24 '15 at 13:55
Where did the comment I responded to go? Yes, 'UnSelect' is probably what I mean. — Worth Lutz, Jul 24 '15 at 14:01
Yes sorry, I realised that you meant another button on the main interface (there is an Unselect all button from the Attribute Table interface) so I removed it from the comment. — Joseph, Jul 24 '15 at 14:09
Yes, the one on the Attribute Table interface has the same icon. I am looking for the on the main interface in the 'Attributes' toolbar. — Worth Lutz, Jul 24 '15 at 14:23

You can get the attributes toolbar and iterate through its actions (buttons) until you get the "deselect" one. Then you can trigger it.

Try this in your QGIS Python console:

for a in iface.attributesToolBar().actions(): 
  if a.objectName() == 'mActionDeselectAll':
    a.trigger()
    break

Thanks, This will work. I'll just have to search for the action in my setup instead of just getting it from iface. – Worth Lutz Jul 24 '15 at 16:26

In QGIS 3.4 using Python Console, also is

iface.activeLayer() 
vlayer.removeSelection()

Really Easy! This could/(should?) be something like: vlayer = iface.activeLayer() vlayer.removeSelection() – Erich Purpur Jul 03 '20 at 12:01

I was stuck on the same issue. I found in http://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/vector.html#selecting-features

layer.setSelectedFeatures([])

it will just select an empty list and so clear selection.

I guess, the removeSelection thing also works!

legend=iface.legendInterface()
layers=legend.layers()
for layer in layers():
    layer.removeSelection()

Brute force ;-) A new selection overrides the old one. Then simply deselect by selecting nothing.

for layer_id in QgsMapLayerRegistry.instance().mapLayers():
layer = QgsMapLayerRegistry.instance().mapLayer(layer_id)
    layer.setSelectedFeatures([feat.id() \
        for feat in layer.selectedFeaturesIterator() if feat.id() < 0])

Maybe there is a more distinguished method, but it works.

For QGIS 3 it will be

layer.deselect(feature_id_here)
