gtkIconSourceNew: gtkIconSourceNew
Description
Creates a new GtkIconSource. A GtkIconSource contains a GdkPixbuf (or
image filename) that serves as the base image for one or more of the
icons in a GtkIconSet, 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.Details
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. GtkIconSet contains a list
of GtkIconSource from which it can derive specific icon variants in
the set.
In the simplest case, GtkIconSet contains one source pixbuf from
which it derives all variants. The convenience function
gtkIconSetNewFromPixbuf 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
gtkIconSetAddSource.
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.
