[SOLVED] PyQt6 custom QtDesigner plugins don't compile

PyQt6 custom QtDesigner plugins don't compile

I'm using PyQt6 and found this instruction how to add plugins to QtDesigner. It worked fine for me and I can see my custom widgets as expected, however, when I use pyuic6 the compilation of the mainpage (which contains such a custom widget) doesn't succeed.

I suspect the reason is that in the Ui-file of the mainpage, there are custom widgets listed but QtDesigner doesn't resolve the path to the definition of these custom widgets. (pyuic states that custom_widget.findtext("header") return None instead of a str)

MainPage.ui:

<ui>
 ...
 <customwidgets>
  <customwidget>
   <class>CustomWidget</class>
  </customwidget>
 </customwidgets>
 ...
</ui>

So how do I tell pyuic6 to use these plugins?

Currently I'm running pyqt6-tools designer -p ./designer_plugins_dir/ from my venv to launch QtDesigner. Is there a way to pass pyuic also a plugins directory or is there a special location in the filesystem where all plugins must be saved to?

Solution

I found the issue. I simply forgot to overwirte the "includeFile()" method which does exactly return a string containing information how pyuic6 should import custom widget.
