Ok, now it looks like below. I don't get any errors but the dictionary
entry show up as a toplevel menu... damn!!
def create_menu(node):
menus = []
for child in node.childNodes:
if child.localName == "item":
menus.append(gtk.MenuItem(child.getAttribute("name")))
if child.localName == "seperator":
menus.append(gtk.SeparatorMenuItem())
if child.localName == "menu": #if child.childNodes:
menuitem = gtk.MenuItem(child.getAttribute("name"))
menu = gtk.Menu()
for mi in create_menu(child): # for each menuitem
menu.append(mi) # append each menuitem
to menu
menuitem.set_submenu(menu) # set menu as submenu
of menuitem
menus.append(menuitem)
return menus
def factory(applet, iid):
doc = minidom.parse("menu.xml")
rootNode = doc.documentElement
menu_bar = gtk.MenuBar()
for cn in rootNode.childNodes: # for each menu under menus
for menu in create_menu(cn): # for each menu in list
menu_bar.append(menu) # append each menu
applet.add(menu_bar)
applet.show_all()
return True
