Question

If you set a fixed checkbox size, the text will be aligned to the checkbox itself. With the standard layout direction, the text will start right after the box, and with right-to-left layout it will end right before the box, just like this (the border is just the widget’s border to indicate the widget/s real size, don’t be confused):

Is there a way to align the text to the other side to achieve this:

Answer 1

As you mentioned you have a fixed size QCheckBox. So easily without subclassing you can get to your desire QCheckBox using style sheets. But unfortunately text-align property just works for QPushButton and QProgressBar. But the alternate stylesheet that you can use is :

QCheckBox{
spacing:100px;
}

With RightToLeft direction for your QCheckBox and this style sheet your checkbox is ready! 🙂 . Change spacing according to your application.
Hope this helps.
