Hi all,
I worked a little with close tab buttons, and I've made a little widget (based on gnome-terminal's code) and a demo.
The default behaviour is the same as gnome-terminal. A try could be to remove the +2 at line 112 of geanyclosetabbutton.c to reduce tab height and get back some tab's top decorations with some themes. In the other hand, then border of the icon could cross the button's border. Next thing is to try this under Windows. If any of you could easily compile and test it under Windows, do it, please.
Any comment? If you think it is a good solution, I can try to make a patch to use it or a derivate in Geany.
Regards, Colomban
