Hi. Where can I find the possible names for icon_names to use gtk_image_new_from_icon_name? I'm trying to port my gtk2 app to gtk3. Thanks.

@aullidolunar gtk3-icon-browser or you can browse /usr/share/icons/<theme>/<size>/<category>.

@andreldm Thanks, man. I also found useful the complete list from freedesktop.org. I have another one: How can I change/update the menu image? Something like a toggle play and pause buttons.

@aullidolunar you need to keep the references for image instances around and call gtk_image_set_from_icon_name using them.

@andreldm OK, OK, I understand: for example in my struct that I pass as user_data for each function as needed. Got it! Thanks.
