Gtk.UIManager.prototype.add_ui

function add_ui(merge_id:Number, path:String, name:String, action:String, type:Gtk.UIManagerItemType, top:Boolean):void {
    // Gjs wrapper for gtk_ui_manager_add_ui()
}

Adds a UI element to the current contents of manager.

If type is Gtk.UIManagerItemType.auto, GTK+ inserts a menuitem, toolitem or separator if such an element can be inserted at the place determined by path. Otherwise type must indicate an element that can be inserted at the place determined by path.

If path points to a menuitem or toolitem, the new element will be inserted before or after this item, depending on top.

Since 2.4

merge_id: the merge id for the merged UI, see Gtk.new_merge_id
path: a path
name: the name for the added UI element
action: the name of the action to be proxied, or null to add a separator
type: the type of UI element to add.
top: if true, the UI element is added before its siblings, otherwise it is added after its siblings.
