When trying to get information about MouseWatcherRegions, I tried using base.mouseWatcherNode.getGroups() but I got the following SystemError:
SystemError: error return without exception set
Then I tried using base.mouseWatcherNode.getGroup(i), but that raises an AttributeError:
AttributeError: 'panda3d.core.MouseWatcher' object has no attribute 'getGroup'
even though it’s in the API docs.
Happens with Panda 1.10.0 (Panda3D-SDK-1.10.0pre-9868d87.exe).
