Here is a patch (I will also open a bug), to add a function gtk_container_get_focus_child to gtkcontainer.c All it does is return the focus_child variable from the container object. The reason this is important is (for example) when the Edit menu is dropped down and copy is selected, it is easy to find out which widget should be sent the "copy_clipboard" signal. Let me know what you think. I also have another function "lookup_focus_widget", which if given one widget (e.g. the menu entry) it will go up the tree until it finds the top container, then back down again until the focused widget is found. I think it would be useful to have as a utility function, however I am not sure where it would be sensible for it go. Do you want the function and if so which source file would make sense?
