gEDA-dev: Toolbar Project

[ehennes-at-NOSPAMsbcglobal_dot_net]

I am looking at making some changes to gschem as a small project.   
However, the changes seem to be more than trivial.  So, I wanted to  
get some feedback from the core developers and also make sure that  
there is no duplication of effort.

I would like to update the toolbar to include more operations  
including toggle and radio.  The best way to get the toggle and radio  
actions seem to be by using GtkAction.  Using GtkAction causes a  
number of other changes.  The following appears what needs to be done:

- Change the way icons are loaded to use GtkIconFactory.

- Create GtkActions for the toolbar and popup menu items.

- Modify callback (i_callback.c) function signatures or add wrappers  
for compatibility with GtkAction callbacks (GSignal).

- Change scheme functions (g_keys.c) to activate GtkActions rather  
than invoking the callbacks directly.  This change keeps toggle and  
radio action's state in sync.

- Update toolbar creation to use new API.

- Update popup menu creation to use new API. (also replace deprecated  
item factory)

- Remove i_update_toolbar (i_basic.c) and associated calls.

I'd also like the core developers opinion of using GtkBuilder and  
GtkUIBuilder for UI construction as apposed to using straight C or  
some form of guile.

Do these modifications seem worthwhile? Is anyone working on this  
already?

Cheers,
Ed
