The later versions of Glade creates a XML file containing defs of more
than one window in the same file, which seems to be more than the current
pyglade code can handle. I hacked up a class to represent the project
file, which can give you the WidgetTree object corresponding to a
particular "window" in the .glade file. This works fine, except for one
detail: When creating a GtkDialog object, the "dialog_new" function
modifies the XML tree from which the dialog should be created, which means
that when you try to create the same dialog the second time around, the
XML tree looks different: particularly, it looks in a way that dialog_new
can't work with, and so you get an exception.
The offending code (~690 in the patched code):
# do some weird stuff because the vbox/action area is already created
node.widget['__wid'] = widget.vbox
children = node.widget.widget
if type(children) != type(()): children = (children,)
for i in range(len(children)):
if children[i].has_key('child_name') and \
children[i].child_name == 'Dialog:action_area':
node['widget'] = (node.widget, children[i])
children[i].parent = node
children[i]['__wid'] = widget.action_area
node.widget[0]['widget'] = children[0:i]+children[i+1:]
break
I can't really get around the problem by cloning the the widget tree, and
it takes too much time reparsing the .glade file every time a widget is
requested so I see no other way than to try to recreate the dialog_new
method so it doesn't need to modify the incoming XML tree. Problem is, I
can't really get to grips with what's going on in the above snippet.
Attached you find a patch for the pyglade/ dir made against 0.6.0 sources
which will allow you to load glade projects.
Anyone got any suggestions?
