Trying to use the Connect Points plugin. I can install it no problem, but when I click Plugins > Connect Points > Settings, I get the error. I have tried re-installing the plugin, uninstalling and installing again. Have also searched for some kind of plugin cache I can clear, but no joy. The stack trace is below, is anyone able to help please?

AttributeError: 'builtin_function_or_method' object has no attribute 'messageBar' Traceback (most recent call last): File "C:\Users/rdeacon/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\connect_points\qgis_connect_points.py", line 96, in showSettings dlg = Dialog( File "C:\Users/rdeacon/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\connect_points\dialog.py", line 164, in init self.fillControls( File "C:\Users/rdeacon/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\connect_points\dialog.py", line 190, in fillControls layerFrom = self.getQGISLayer(curPointsLayerFrom) File "C:\Users/rdeacon/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\connect_points\dialog.py", line 235, in getQGISLayer QgisPlugin(iface=self.parent).showMessageForUser( File "C:\Users/rdeacon/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\connect_points\qgis_plugin.py", line 82, in showMessageForUser self._iface.messageBar().pushMessage( AttributeError: 'builtin_function_or_method' object has no attribute 'messageBar'

I guess you found a bug. For a temporary solution, you can try the follows:

  1. Go to the plugin folder (Settings > User Profiles > Open Active Profile Folder, and navigate to python > plugins > connect_points)

  2. Open qgis_connect_points.py. Add a new argument, as in the image (Line 103-104):

    103    self._iface.mainWindow(), self._iface

    enter image description here

  3. Open dialog.py. Add iface=None and self._iface = iface to __init__ as in the image:

    56  parent=None, iface=None
    59  self._iface = iface

    enter image description here

  4. Change self.parent to self._iface around Line ~235-240

    enter image description here

  5. Restart QGIS.

  • I'm getting a new error now 'Couldn't load plugin 'connect_points' due to an error when calling its classFactory() method // TabError: inconsistent use of tabs and spaces in indentation' Followed by some file references, then the same TabError again. Note - I don't have a code editor with numbered lines, and don't have permissions to install software on my computer, so it's possible I made the edits in the wrong places, as I was doing my best with windows notepad. Are you able to provide a little more context with your screenshots so I can make sure I 've edited correctly please? Dec 6, 2022 at 21:52
  • Check indentation. It should be as in the image. Dec 8, 2022 at 6:45
