Re: Deprecated function ed icons on button

[Gergely Polonkai <gergely polonkai eu>]

Hello,

yes, stock icons are now deprecated in favour of icon names, preferably
symbolic icons (especally if you are building a GNOME component). Creating
image buttons may seem a  bit harder than before.

As you may have already seen, a GtkButton is subclassed from GtkBin, which
means you can pack another widget into it. It can be a GtkLabel, or even a
GtkEntry (this sounds crazy), or, in your case, a GtkImage.

Create a GtkImage with gtk_image_new_from_icon_name(), then add it to the
button with gtk_container_add(GTK_CONTAINER(button), image).

And now that you hopefully understand the concept, I'd like to introduce
gtk_button_new_from_icon_name() :) For this, you need GTK 3.10, though, but
it's a shorthand for the above.

Personally, I prefer using Glade/GtkBuilder, although Glade doesn't support
some of the newer widgets, and gives you hard times with other stuff.

Best,
Gergely Polonkai
