Re: [pygtk] MVC and TreeView
Actually, I figured out the last question. But here is one that bears more consideration. My data is a dictionary of objects. I use a tuple of 3 properties of those objects in a list, which I then sort. Now I can iterate over the list, and access the dict in the order I want. How do I translate this sorting order to the TreeView or model? Is it as simple as setting up a method that iterates over the dict in order, and passing that method to the TreeView? jm -- My other computer is your Windows box. ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
Re: [pygtk] MVC and TreeView
Hi David, the tips you gave me were very helpful. I have a working prototype now that has helped me understand the basics. But what if I want to still have multiple columns? I'm still not quite sure where those should be added or accounted for. jm -- My other computer is your Windows box. ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

Best to avoid redundancy altogether if you can by directly using your objects. You can put the actual objects in the ListStore and then set the cell contents using a callback as described in the FAQ. http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq13.029.htp This is the easiest way to do it, but you lose interactive searches (which must be on a text column in the TreeModel.) Or you can write a custom TreeModel that returns values from your objects. This is more work since you have to write all the model methods and are responsible for sending out the right signals when the model changes.

[pygtk] MVC and TreeView
Hi all, if I have a set of objects and show their properties in a TreeView, is it better to change the original objects then rebuild the ListStore, or extract the changes from the ListStore and modify the original objects? jm -- My other computer is your Windows box. ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
[pygtk] Subclassing GtkWidget in PyGTK
Hello friends I just added an example in CVS (http://cvs.gnome.org/viewcvs/gnome-python/pygtk/examples/gtk/widget.py?rev=1.3&view=markup) That demonstrates how to subclass a GtkWidget in PyGTK. Unfortunately it requires latest CVS, since I added a bunch of stuff required by it (modifying GdkEvent's members for instance). -- Johan Dahlin <[EMAIL PROTECTED]> ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
