Gtk.IconView uses a Gdk.CellRendererPixbuf to render the icons in the
iconview. Gtk.IconView has a property "gicon" which can be used to set
the icon from a GLib.Icon
In other words, you need a Gtk.TreeModel with a column for your GLib.Icon
Then use the Gtk.CellLayout.set_attributes function to set the "gicon"
property of the CellRenderPixbuf in the IconView to the number of the
column in the TreeModel that holds the gicon
The only slight issue is obtaining the CellRendererPixbuf as it is not
available easily from the IconView object, however something like this
should work:
Gtk.CellRendererPixbuf get_cr_pixbuf(Gtk.IconView icon_view) {
var crs = icon_view.get_cells();
foreach (var cr in crs) {
if (cr is Gtk.CellRendererPixbuf) {
return cr;
}
}
stdout.printf("Can't find pixbuf cellrenderer (shouldn't happen)");
assert_not_reached();
}
var cr_pixbuf = get_cr_pixbuf(icon_view);
icon_view.set_attributes(cr_pixbuf, "gicon", GICON_COLUMN_NUMBER);
If you need any more pointers, just ask :)
Hope this helps
