[pygtk] defs in gnome-python
Hi, I noticed the .defs files in gnome-python/gnome-python are not copied to shape/pygtk/2.0/defs. This is very unpleasant since I inherit from GnomeCanvas for DiaCanvas view class. I posted a bug (#80448) on bugzilla.gnome.org and applied a patch.

[pygtk] Widget tree traversal
I can't find anything to get the parent of a widget. There are methods to reparent and unparent but I don't see any method to just retrieve the parent widget.

You can't reopen a window that has been destroyed, you can only recreate
it. You might prefer to set hide_on_delete() for the window and then
use show() and hide() to manage them.

I'm using 0.6.8 for GTK+ 1.2, so it didn't work - but I'm getting a
similar error whenever I try re-opening a window which has been
destroy()ed, so it's surely just some silly error I've made.
btw; is it recommended to develop for the 2.x platform? I haven't
checked out the GNOME 2.0 prereleases yet, as I want a stable
environment - and I heard there were quite a few conflicts between gtk
1.2 and 2.0 applications.

[pygtk] dialog window function
Hi all
I have just started out with Python, and am playing around a bit with
pygtk and libglade. I have some experience with structured programming,
but this is my first encounter with object-oriented programming.
I am trying to create a generic function for a Yes/No type dialog box,
but the code seems a bit "clunky" - would anyone care to look at it and
give me some pointers to how this could be done in a sexier fashion?
Also; I seem to be having some problems when the function is called the
second time around; Python gives this error:
File "main.py", line 142, in dialog_yesno
label.set_text(text)
AttributeError: 'NoneType' object has no attribute 'set_text'
Any ideas?
Here is the code for my dialog function :
def dialog_yesno(text):
"Displays a yes/no dialog, returns true on yes, false on no"
global xml, status
def yes(obj):
global status
status = 1
print "yes"
window_yesno.destroy()
gtk.mainquit()
def no(obj):
global status
status = 0
print "no"
window_yesno.destroy()
gtk.mainquit()
def destroy(obj):
obj.destroy()
gtk.mainquit()
# get pointers to relevant widgets
window_yesno = xml.get_widget("window_yesnodialog")
label = xml.get_widget("yesno_text")
yesbutton = xml.get_widget("yesno_yes")
nobutton = xml.get_widget("yesno_no")
# set the dialog window label
label.set_text(text)
# default status is false
status = 0
# map signals
yesbutton.connect("clicked", yes)
nobutton.connect("clicked", no)
window_yesno.connect("destroy", destroy)
# Show the window
window_yesno.show()
gtk.mainloop()
# Return our value
return status

I will definitely be having a look at that at some point, but for the moment I have to stick with the old versions as porting the rest of our code base over to 2.0 would be a big job.

[pygtk] Inheriting from GObject
Hi, I'm working on a python wrapper for DiaCanvas2 (hence the previous postings ;-) and came up with some thoughts... First of all: the properties and signal handling in Python is really neat. But it's screaming for more... Shouldn't it be nice if classes inherited from GObject (or GTK+ objects or whatever) can override the methods defined in the *Class structures? I noticed property handling works nice this way (although it works a little different, so it's not comparable :-( ). Inheriting from a GObject, calling __gobject__init__() in the __init__() method and registering it declaration creates a new GType. It would be nice if an object could set some custom handlers for *Class methods itself. In case of a DiaCanvasItem (and GnomeCanvasItem) this would mean that if you create your own canvas item you can override the default 'update' method by creating a 'on_update' method or something like that in your python class and PyGTK takes care of the rest. This creates a few problems: - what happens if you inherit from a python class which is inherited from a GObject class? - How do we define those handlers? Next: it would also be very neat if you can inherit from a GObject and a set of interfaces. E.g. class MyClass (GObject, GtkTreeModel): def on_get_value(self): pass The type registration stuff should be able to handle this AFAICS. This means of course that overriding *Class methods should work properly. And last: could it be possible to depricate the gobject.type_register() function? Could it be done during the first call to GObject.__gobject_init__()? That would make the python code more clean. I hope I made myself clear ;-) ...

[pygtk] constructors in h2def.py
Hi,
I used h2def.py this weekend and noticed it does not create
'is-constructor-of' entries in the generated code. I started browsing
the code and noticed this is a todo item. I solved it this way:
- a constructor function ends with '_new' and returns a pointer
- h2def converts the text before the _new to a class name and writes
a constructor entry.
Here's the patch.
Regards,
Arjan
