[pygtk] Trying to wrap a gobject

2009-07-20 Thread gabriele lanaro

Hi, I'm try to wrap the eggtrayicon like in the tutorial at this page:
http://www.ibm.com/developerworks/linux/library/l-wrap/

The tutorial il very old, but It's better than the faq, so I have a problem:
I generate with h2defs and eggtrayicon.h the trayicon.defs file
I wrote a trayicon.override
I wrote a simple Makefile to generate the trayicon.c
Now I encounter this error:

pygobject-codegen-2.0 --prefix trayicon\
--register `pkg-config --variable=defsdir pygtk-2.0`/gdk-types.defs \
--register `pkg-config --variable=defsdir pygtk-2.0`/gtk-types.defs \
--override trayicon.override \
trayicon.defs  trayicon.c

Re: [pygtk] Help passing a widget to another class instance

2009-07-20 Thread Kim Adil

Solved:

I had to add a self.xxx variable to the init method of the page class 
and make it equal to the pparent, so that the save method on the page 
class had a variable it could access. I would be interested in what 
people consider good practice in this sort of situation.

 Hi,

 I have a class for a glade window, that contains a notebook and I have 
 another class for notebook pages. I want to pass the (pointer to) 
 notebook widget when I create the the page object, so I can change the

 the page) but I get the error:

 print self.pparent.get_current_page()

[column.get_title() for column in treeview.get_columns()]

I assume you are referring to the column names of a gtk.TreeView, since 
gtk.ListStores don't have column names.
