How to remove QScrollbar scroll buttons?

Question

I want to style QScrollBar to look like this without the indicators in the end

I tried with the stylesheets:

QScrollBar::up-arrow:vertical, QScrollBar::down-vertical  
{  
      border: none;  
      background: none;  
      color: none;  
}

But this hides the indicator arrow not the 2 buttons at the end

You can use something like this:

QScrollBar:vertical {
background: #2f2f2f;
width: 15px;
margin: 0;
}

QScrollBar::handle:vertical {
background: #5b5b5b;
}

QScrollBar::add-line:vertical {
height: 0px;
}

QScrollBar::sub-line:vertical {
height: 0px;
}

QScrollBar::add-page:vertical, QScrollBar::sub-page:vertical {
height: 0px;
}

The classes you were looking for are add-line, sub-line, add-page and sub-page. Since they support the box-model, you can just set their height to 0 to make them disappear.

The code above was tested with Qt 5.9.
