Scrollbar handle with rounded edges?

@raven-worx
hehe, yep it doesn't refresh while the editor is open so while going to check docs
to paste something, it does happen someone already posted an answer.
However, there is often slight variations, like your answer is better suited to set from
code while mine is just from the stylesheet editor. So in my book, its rarely
wasted efforts anyway :)

QScrollBar:vertical {
            border: 0px solid #999999;
            background:white;
            width:10px;    
            margin: 0px 0px 0px 0px;
        }
        QScrollBar::handle:vertical {         
       
            min-height: 0px;
          	border: 0px solid red;
			border-radius: 4px;
			background-color: black;
        }
        QScrollBar::add-line:vertical {       
            height: 0px;
            subcontrol-position: bottom;
            subcontrol-origin: margin;
        }
        QScrollBar::sub-line:vertical {
            height: 0 px;
            subcontrol-position: top;
            subcontrol-origin: margin;
        }

one thing to notice, your border-radius: 4px; and the width:10px; should match up.
if you make it too narrow, it wont be round.

It's working, but I'm unable to change the scrollbar's (not handle) background color.It's set to white, when I change it to Gray, the background becomes checkered. Also, tried adding background-color in add-line/sub-line but didn't work.

Have you already check out the QT StyleSheet examples on Qt Documentation ?
https://doc.qt.io/qt-5/stylesheet-examples.html#customizing-qscrollbar

Hi
Its actually not the background but sub-page and add-page you see. if you remove color from them , then
background works.

add to stylesheet

QScrollBar::sub-page:vertical {
background: none;
}

QScrollBar::add-page:vertical {
background: none;
}

Working great.

However, I also tried this on QTreeWidget, Qt Designer shows correct scrollbar but when I run the application, its showing standard windows scrollbar?

and is it possible to have scrollbar only disable when mouse enters the widget scrollbar is attached to e.g. on line edit or treewidget?

Hi. it should also work for QTreeWidget.
Do you apply it directly to it or to its parent ?

-and is it possible to have scrollbar only disable when mouse enters the widget scrollbar is attached to e.g. on line edit or treewidget?

You mean they are hidden but only shows when mouse is over ?
lineEdits cannto have scrollbars.

I applied stylesheet to QTreeWidget

Yes

lineEdits cannto have scrollbars.

@Taytoo
Hi
can you try applying it to main window instead.
(i assume the QTreeWidget lives in mainwin)

Well show on hover thing is not included by default.
I think you can make it work by overriding Enter/Leave
events
https://doc.qt.io/qt-5/qwidget.html#enterEvent
and show hide the scrollbars.
If you dont want to subclass, you can also try with
Event filter
https://doc.qt.io/qt-5/eventsandfilters.html

.

@mrjj That worked. Thanks!

One would assume since scrollbar is in QTreeWidget, the style needs to be applied there though?

That's a NodeBB issue. What answer did you want to mark as the solution ?

@SGaist mrjj's first reply to my post answered the main question. Later posts were all about tweaks, so I guess first reply is the answer.

Done :-)
