You were working so hard on the xfce widgets I wanted to try and
contribute something to that effort.
xfce_iconbutton is a gtk_button with an automatically scaled icon. It's
based on GtkButton and I just add a gtk_image containing the icon.
It works for me, but the automatic scaling part turned out to be a lot
more complicated then I thought. I didn't want to reimplement all the
button functions myself, so I decided to just connect to the
'size-allocate' signal. However if I set the image in the size-allocate
handler you get a race condition (new image => new size => new
image => etc.).
I 'solved' it by having a flag indicating if the icon was just scaled.
So effectively I never scale on every second size-allocate event. This
seems to work fine, but it also feels wrong.
I can either try to reimplement the gtk_image widget or the gtk_button
size_allocate function. Both are not entirely trivial.
Could you perhaps have a look and tell me what you think? There is an
example for it as well.
