Description ned 2016-10-05 22:57:28 UTC

In older versions of Plasma (<5.6.x?), it was possible to mouse-scroll to cycle through all of the windows in a single group on the task bar. If you scrolled on an ungrouped window, it would scroll through all windows in the task bar.

In more recent versions, it appears that the mouse scroll only scrolls through all windows on the task bar, regardless of whether the window you're hovering over in the task bar is in a group or not.

This feels like a regression, as the old behaviour was really useful, for instance for looking through a bunch of images or documents at once, and comparing them... If there was a valid reason for removing this behaviour, would it at least be possible to get it back as an optional behaviour?


Reproducible: Always

The Task Manager was rewritten for 5.7. The wheel should still go into groups and go through the grouped windows, and at the time I verified it worked. Perhaps we broke it again, I'll look into it.

Can't reproduce it on my system.

Comment 3 Eike Hein 2016-10-06 08:39:22 UTC

I misunderstood this ticket; I thought the problem was that the wheel doesn't descend into groups, but the problem is that you want it to only switch windows within the group.

Only switch between windows within the group when using the wheel above a group parent.
