Fix mouse wheel scrolling in pager and task selector (2.51 KB, patch)

Description Sam Morris 2012-04-10 11:57:08 UTC 
Since upgrading to GTK+ 3.4, the mouse wheel does nothing when scrolled on top of the window switcher & workspace switcher applets.

According to GTK+'s NEWS file, since GTK+ 3.3.18 "To receive scroll events, widgets must now set either GDK_SCROLL_MASK or GDK_SMOOTH_SCROLL_MASK". VTE suffered from a similar problem in bug 671305 so perhaps gnome-panel also needs to make this change.

Indeed. Should be rather straight-forward.
Comment 2 Christian Persch 2012-05-11 19:13:23 UTC 
-> libwnck.

Fix mouse wheel scrolling in pager and task selector

Add the GDK_SCROLL_MASK to the window events, and add dummy handling of
GDK_SCROLL_SMOOTH events so as to not crash if they occcur.

Untested but should work :-)

Bug #673833.

This was not enough for the tasklist, but I committed something else there that makes it work.
