Gtk.IconSource Class
A GtkIconSource contains a Gdk.Pixbuf (or image filename) that serves as the base image for one or more of the icons in a Gtk.IconSet, along with a specification for which icons in the icon set will be based on that pixbuf or image file. An icon set contains a set of icons that represent the same logical concept in different states, different global text directions, and different sizes.

Remarks

A Gtk.IconSource contains a Gdk.Pixbuf (or image filename) that serves as the base image for one or more of the icons in a Gtk.IconSet, along with a specification for which icons in the icon set will be based on that pixbuf or image file. An icon set contains a set of icons that represent the same logical concept in different states, different global text directions, and different sizes.

So for example a web browser's "Back to Previous Page" icon might point in a different direction in Hebrew and in English; it might look different when insensitive; and it might change size depending on toolbar mode (small/large icons). So a single icon set would contain all those variants of the icon. Gtk.IconSet contains a list of Gtk.IconSource from which it can derive specific icon variants in the set.

In the simplest case, Gtk.IconSet contains one source pixbuf from which it derives all variants. The IconSet(Gdk.Pixbuf) constructor handles this case; if you only have one source pixbuf, just use that function.

If you want to use a different base pixbuf for different icon variants, you create multiple icon sources, mark which variants they'll be used to create, and add them to the icon set with IconSet.AddSource(IconSource).

By default, the icon source has all parameters wildcarded. That is, the icon source will be used as the base icon for any desired text direction, widget state, or icon size.
