Your title and first line read:

How to always fix the button to the left side using QtDesigner?

GUI where a button always needs to be fixed to the right side of the screen

Those do not seem consistent to me. As per @mpergand, are your "bottom bar and the button in a horizontal layout"?

@JonB maybe, this will help you understand my layout.

@JonB in the frame of the bottom bar has no vertical or horizontal layout

And the "red no entry" symbol Designer shows on the QFrame warns you that it needs a layout.

@JonB what layout do you need to use in which it is possible to achieve my goal?

Put the bottom bar and the button in a horizontal layout.

Then if you want the button on the right, I can't remember whether the layout allows you to right align, or put a stretch to the left if not.

Yes you can.

Now, this bottom bar ressembles very much to a QStatusBar in a QMainWindow and you can add any widget to it with:
addPermanentWidget(QWidget *widget, int stretch = 0)

@mpergand @JonB

and how do I do this using qtdesigner? I added a column ed layout to my bottom bar.

[_jao_victor_]

now the button is central

Right-click on the button and choose :
Layout Alignment->Right

@mpergand the alignment layout is not selectable, what will be the reason?
