Created attachment 5845 Add TunarxActionMenu class to thunarx Thunarx menu providers which need submenus need to create their own class switch inherrits from GtkAction to be able to create a submenu. With ThunarxActionMenu the menu provider can create a GList of GtkActions and create a submenu from that. This could be usefull to multiple plugins. That is why I would like to see this in thunars.
With the introduction of ThunarxMenu and ThunaxMenuItem in Thunar 1.7.0 what is requested is now possible.
