GtkCellView API changes

[Anders Carlsson <andersca gnome org>]

Hello,

I've taken a look at the GtkCellView API which has been made public in 
2.5. I think that a couple of API additions and changes are needed for 
it to be more useful and more like the rest of the GTK+ API:

void gtk_cell_view_set_value (GtkCellView     *cell_view,
                              GtkCellRenderer *renderer,
                              gchar           *property,
                              GValue          *value);

void gtk_cell_view_set_values (GtkCellView     *cell_view,
                               GtkCellRenderer *renderer,
                               ...);

gtk_cell_view_set_value is good here, but gtk_cell_view_set_values takes 
 pairs of property names and _GValues_. I suggest that we replace this 
function with

void gtk_cell_view_set (GtkCellView     *cell_view,
			GtkCellRenderer *renderer,
			...)

and

void gtk_cell_view_set_valist (GtkCellView     *cell_view,
   			       GtkCellRenderer *renderer,
			       va_list          var_args);

which is more like all other multiple property setting functions in GTK+.

Also,

void gtk_cell_view_set_cell_data (GtkCellView     *cellview);

which is supposed to be called when the underlying tree model changes 
should be renamed to

void gtk_cell_view_update (GtkCellView *cellview);

to better reflect what the function does. Having a set function without 
any extra arguments seems a little awkward to me.

Finally, it'd be nice to have the cell view be able to pass on mouse 
clicks/keyboard presses to the cell views' ::activate handlers. This 
would be done using

void gtk_cell_view_set_can_activate (GtkCellView     *cell_view,
			             gboolean         can_activate);

gboolean gtk_cell_view_get_can_activate	(GtkCellView *cell_view);

when the can_activate flag is true, mouse clicks on the cell view will 
be passed on to the cell views' ::activate handlers, if any. Also, the 
individual cells will be focusable and in the focus chain, like a single 
row in the tree view.

I'd like comments and/or suggestions...

Thanks,
Anders
