Stylesheet for scrollbar in QScrollArea

[eukr]

Hello, how can i set qss style for scrollbar in QScrollArea.

What i have tried..
In qss for QScrollArea i set code from documentation:

QScrollBar:vertical {
    border: 2px solid grey;
    background: #32CC99;
    height: 15px;
    margin: 0px 20px 0 20px;
}
QScrollBar::handle:vertical {
    background: white;
    min-width: 20px;
}
QScrollBar::add-line:vertical {
    border: 2px solid grey;
    background: #32CC99;
    width: 20px;
    subcontrol-position: right;
    subcontrol-origin: margin;
}

QScrollBar::sub-line:vertical {
    border: 2px solid grey;
    background: #32CC99;
    width: 20px;
    subcontrol-position: left;
    subcontrol-origin: margin;
}

But nothing.. scrollbar in QScrollArea still have standard style.

Hi,

How are you setting that style sheet ?
How are you creating your QScrollArea ?

What version of Qt are you using ?
On what platform ?

Below is my working code cor Vertical Scroll Bar

QScrollBar:vertical {border-color: #424242;border-width: 1px;border-style: solid;
    background-color: #32CC99;width: 25px;margin: 21px 0 21px 0;
    QScrollBar::handle:vertical {background-color:white ;min-height: 25px;}
    QScrollBar::add-line:vertical {border: 2px solid black;background-color: #32CC99;
    height: 25px;subcontrol-position: bottom;subcontrol-origin: margin;}
    QScrollBar::sub-line:vertical {border: 2px solid black;background-color: #32CC99;
    height: 25px;subcontrol-position: top;subcontrol-origin: margin;}

the code you are using is for Horizontal scroll bar i think so, as for vertical scroll bar margin should be

margin: 20px 0px 20px 0px;

Hope this helps .

Hello, I have same trouble.
I use QtDesigner to create .ui files and VS Code to run PySide6 code.
This is my QSS code.

QScrollBar:vertical {
	border: none;
	background: rgb(75, 75, 75);
	width: 14px;
	margin: 15px 0 15px 0;
	border-radius: 0px;
}

I set style sheet and create QScrollArea in QtDesigner.
Preview in QtDesigner can show this options on my QScrollBar, but when I run my Python code with this form I see default scroll. Where did I go wrong?

@NikM Hi, did you fix the error, even I see the customized bar in designer but it rolls back to default style when I preview the widget. I saw a post on stackoverflow too: https://stackoverflow.com/questions/66557285/my-pyqt5-custom-scrollbar-stylesheet-doesnt-apply but, didn't quite understand what parent element meant.
