Revision as of 12:12, 4 July 2012

This page is being performed while I'm porting InfoSlicer Activity to Gtk3.

There is a ticket with some useful information that I'm using on the porting and to keep tracking this port. Besides, this wiki page will be useful to write some code snippets about what are the difficulties that I'm having on the port and maybe can be useful for someone else.

I will take this guide as reference on the Gtk3 porting.

Remove hippo

First of all, I had to remove the hippo related things and the sugar-port (ticket) wrapper.

Signals

Change TYPE_PYOBJECT type from a signal

We should replace the TYPE_PYOBJECT

'article-selected' : (SIGNAL_RUN_FIRST, None, [TYPE_PYOBJECT]),

by the Python's object type

'article-selected' : (GObject.SignalFlags.RUN_FIRST, None, [object]),

Working with threads

InfoSlicer uses threads to retrieve the information from internet (Wikipedia articles). The pygi script will replace it by Gdk.threads_init() by I found this is not the correct way to do this. In fact, I was dealing with some strange behaviour of the Activity because of this. So, I used:

from gi.repository import GObject
GObject.threads_init()
