difference between buttons shown and not shown

As per the discussion in the VDG channel: 

could we make the scrollbar v and ^ buttons always show, not only on hover? 
Otherwise it always looks like you can scroll more in that direction, even though you are at the bottom / top. 

It also doesn't really save space or look slimmer / nicer.

BTW, all the action is in ./kstyle/animations/breezescrollbardata.cpp, if you want to try your hand at producing a patch. I gave it a shot tonight but my head is spinning and I need to go to sleep.

Hint. 
The action is not in ./kstyle/animations/breezescrollbardata.cpp
Comment 3 Nate Graham 2018-06-05 12:54:22 UTC
Yeah, I didn't have much luck there either. I found two instances of this in kstyle/breezestyle.cpp:

// no mouse over and no animation in progress, don't draw arrows at all
else if( !widgetMouseOver ) return Qt::transparent;

Removing those made the arrows appear by default, but after hovering the scrollbar groove and moving the mouse out of it, they disappear.
