The Gdk::RGBA data type was introduced to replace Gdk::Color in
Gtkmm 3.0 [1], with Gdk::Color being deprecated in Gtkmm 3.10 [2].
With this commit we make the change to Gdk::RGBA data type which is the
modern replacement to Gdk::Color. Gdk::RGBA can be used almost as a
drop in replacement because it keeps most of the Gdk::Color interface.
Also, this commit removes the C Gtk call introduced during the
port-to-gtk3 patchset by commit:
5379352766
repare-for-gtk3: Prepare for removal of Gtk::Widget::modify_fg() (#7)
[1] Gtkmm 3.0.1 NEWS file
https://gitlab.gnome.org/GNOME/gtkmm/blob/3.0.1/NEWS#L48
* RGBA replaces Color, though Color still exists because it is
used by TextView. We hope to deprecated Color completely in
gtkmm 3.2.
[2] Gtkmm 3.10.0 NEWS file
https://gitlab.gnome.org/GNOME/gtkmm/blob/3.10.0/NEWS#L127
Gdk:
* Deprecate Color.
