Subject: infobar: Activate default action on clicks
X-Git-Tag: archive/raspbian/4.4.1+ds1-2+rpi1^2~18^2~20^2~341
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=45309811c564d4e893d51eab403173079a954e43;p=gtk4.git

infobar: Activate default action on clicks

When we have a default action set on the infobar, activate it
for clicks anywhere in the infobar.  Also add an .action style
class in this case, so we can add a hover highlight to the infobar
just for this case.
