<![CDATA[Customize QDoubleSpinBox text align with CSS]]>Hello,

I try to customize a double spin box.

In Qt designer I have the following lines in the style sheet editor.

QDoubleSpinBox {font-size: 20px; text-align: right}

QPushButton{text-align: right}

0970bd91-7a0c-4a8e-b29a-48a878de3e37-image.png

text-align: right has no effect in the spin box

How can I change the alignment in the spin box?

A QSpinBox has an internal QLineEdit child for the number text. I won't lie to you, I have had trouble accessing that fully, and reported a bug, but it never got addressed. But I did successfully change the text alignment (mine was from code, not stylesheet, for this). That is what you will need to set the text-align on. Try it from stylesheet rule (QDoubleSpinBox.QLineEdit or whatever the docs say the syntax is a for a child, I can't remember?), though that may be what I found did not work right. Or to verify my claim set the stylesheet directly from code on spinBox->lineEdit() to check it works. Note that method is protected, to access you either need to sub-class or use spinBox->findChild<QLineEdit *>().
