Description:
For qt4 apps middle mouse button click to scroll-bar doesn't scroll. Tested with vlc and Amarok, so it seems to be specifically qt4 library issue. Also, I relatively recently moved to Archlinux, for ≈4-5 month, and I seem to recall it worked here before. Additional info: * package version(s) 4.8.7-10 Steps to reproduce: 1. Open a VLC or Amarok 2. Make up a playlist long enough for scrollbar to appear. 3. Click the empty space after the bar with middle mouse button. It ought to scroll the bar till the point of click, but instead it does nothing. |
This task depends upon

May that then be a theme issue? What theme are you using. FWIW, I didn't change the default one though.
Neither it's a DE issue: with a new user I tested it with gnome-on-wayland (because it was easy to run without logging out). ATM I am in Awesome WM with $XDG_CURRENT_DESKTOP=KDE.
I'll have to check a theme, but I seems to have had Breeze too. But may be it's Qt5 theme, i.e. I don't know what theme is set for Qt4.
Turns out the problem is indeed the theme. The default one was "Desktop Settings(Default)", and it did draw nothing in the preview box. I set it to "GTK+", an example appeared in the preview box, and middle mouse button click started working!
I should say, I surprised, because unlike GTK, Qt doesn't allow to set Emacs/readline movement shortcuts in textboxes, so I thought that theming capabilities are pretty much limited to appearance.
