[bitbake-devel] [PATCH 03/10] ui/crumbs/persistenttooltip: fix colours on darker themes

[Joshua Lock]

Darker gtk+ themes, such as the one used in Ubuntu Unity, revealed that the
PersistentTooltip styling wasn't setting the label colour correctly.

Set the label foreground colour to the tooltip_fg_colour value as read from
gtk-color-scheme property of the system settings.
