QUiLoader flawed/not providing name for Layouts. Workaround?

[wysota]

and sure enough the interface behaves perfectly.

It doesn't as you can't access the layout

I have not seen any mentioning that you should place dummy widgets around every single layout that shares hierarchy level with other widgets.

I didn't say you should. Designer places floating layouts into QWidgets to be able to save the file. There is a thread on this forum which mentions that.

Simplified version of the interface file is attached.

So which layout you want to access?
