I am updating a plugin from QGIS 2 to 3. I need to iterate through the groups (the names are dynamic) and remove them with their respective child layers. I need to get a list of groups and then iterate through the groups and delete them. The original code is as follows:
legend = self.iface.legendInterface() group_names = legend.groups() rev = self.groups[:] rev.reverse() ... for i, group in enumerate(rev): legend.removeGroup(group)
group_names = legend.groups() fails with the message 'QgsLayerTree' object has no attribute 'groups'
What is the proper container of the groups and how do I access the collection; and, once found, how do I delete those groups? A search for information on how to remove groups from a layer tree in QGIS 3 has proven fruitless.
