OK, no answer from experts yet.
I can remember that I used this Ruby code for that task:
@changed_handler_id = self.signal_connect('changed') {|w|
if @pda
if w.active != -1
i = w.active_text.to_i
if i != (@major ? @pda.schem.major_grid : @pda.schem.minor_grid)
if @major then @pda.schem.major_grid = i else @pda.schem.minor_grid = i
end
@pda.schem.active_grid = i if radio_button.active?
@pda.redraw
end
end
end
}
So active property of
https://developer.gnome.org/gtk3/stable/GtkComboBox.html#GtkComboBox--active
can be used to detect if an item was selected from list.
