Why the bottom of main window covers other widgets?

Why do this happen? I tried to fix the python code manually to remove it, but I can't find it.

Is your widget based on QMainWindow? Have you implemented a class based on QWidget containing a layout and your UI and set it as QMainWindow's "centralWidget"?

If your class is not based on QMainWindow but on QWidget or QDialog, have you created a layout for the window with your buttons and line edits laid out inside it?

What I see in your screenshot is what I would expect to see if you were not using a layout or were using it incorrectly.

It looks like this.
What did I wrong? I have already implemented centralWidget

[Lesiok]

centralwidget has no layout.

Then do you mean that I have to remove default centralWidget and make another widget that has a specific layout?

[Lesiok]

No, just add layout to centralWidget. Object centralLayout is not layout for centralWidget.
