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

[_jao_victor_]

@JonB The main screen has a layout in lines, only has 2 lines: the text editor and the bottom bar. Only this line layout is set in this GUI

So what have you done in the designer to tell it where you want the button?

Also you say

where a button always needs to be fixed to the right side of the screen,
the button does not follow the right edge of the screen.

and also

fix the button to the left side using QtDesigner
the button should not be in the middle of the bar but pasted to the left edge of the GUI

so I don't know which you want.

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

@JonB sorry, it was a dgitation error. I edited my question.

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.

[_jao_victor_]

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

[JonB]

@_jao_victor_
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

[mpergand]

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

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