Why doesn't scaling work in QT Designer?

Question

User interface

I ran into problems that when you resize a window, the widgets do not change with it, but remain in place. Googled and added widgets to Layout. Nothing has changed, why is that? Maybe something needs to be added?

Answer 1

Look in the object inspector for "centralwidget". This is the window's root layout and should be laid out. The layout you've laid out scales the widgets internally, but doesn't scale itself. Centralwidget is always deployed to the entire window.
