Well, if you are creative enough, you can just fake it using pixmaps.
(When I use 'tree' I refer to the specific ctree you are dealing with)
Let's say you have a dictionary of settings, like this:
self.pixmaps = {}
self.pixmaps['On'] = gtk.create_pixmap_from_xpm(tree, None, 'On.xpm')
self.pixmaps['Off'] = gtk.create_pixmap_from_xpm(tree, None, 'Off.xpm')
you build the tree with:
columns = [some text here]
(for nodes):
node =
tree.insert_node(parent,None,columns,5,None,None,None,None,gtk.TRUE,gtk.FALSE)
(for branches):
node =
tree.insert_node(parent,None,columns,5,None,None,None,None,gtk.FALSE,gtk.FALSE)
and on each of them you call (setting is either 'On' or 'Off'):
(this is a function):
(xpm,xpm_mask) = self.pixmaps[setting]
col = 1
tree.node_set_text(node,0,setting)
(bleh,bleh,bleh,bleh,bleh,bleh,is_leaf,expanded) = tree.get_node_info(node)
tree.set_node_info(node, setting, 5, xpm, xpm_mask, xpm, xpm_mask, is_leaf,
expanded)
neat!
Now, when you want to "update" the pixmap as a result of some
user or programmatic action, you just do the same thing again (above)
with the appropriate setting.
See?
