Description Chandni Verma 2013-08-14 09:34:51 UTC 
GtkExpander does not allow us to have it's label-widget receive button-press-event (or any event for that matter) on its children.

A hack described here: http://gtk.10911.n7.nabble.com/GtkExpander-label-widgets-using-buttons-as-td1738.html , allowed me to make labels clickable inside a GtkExpander. I have to reset the label-widget after the expander has been realized to get the events on the children of label-widget.

From a quick check, the gtk_widget_map() call in gtk_expander_map() should happen at the end of the function, after the gdk_window_show() there:

https://git.gnome.org/browse/gtk+/tree/gtk/gtkexpander.c#n789

This code dates back to the GtkExpander addition, it looks to me like this was done on purpose, the same way buttons-within-buttons are prevented by having the GtkButton's GdkWindow stay over childrens'. This seems sensible for buttons, not as much for expanders.

I'll get to making a patch and testing this later today if no one beats me to it.
