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.
Code Snippets
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()
gtk.gdk._2BUTTON_PRESS
We should replace:
gtk.gdk._2BUTTON_PRESS gtk.gdk._3BUTTON_PRESS
by:
Gdk.EventType._2BUTTON_PRESS Gdk.EventType._3BUTTON_PRESS
Missing / Problematic things (not ported yet)
- Select text from the Edit View (TextView) and the Home View. This error happens in many places of the code.
Traceback (most recent call last):
File "/home/humitos/Activities/InfoSlicer.activity/infoslicer/widgets/Readonly_Textbox.py", line 116, in motion_notify
self.emit("motion-notify-event", event)
TypeError: could not convert type EventMotion to GdkEvent required for parameter 0
