Re: Treeview Undo

I was actually using the treeview to store the data.  It is a small
dataset and then writing the data to an xml I was looking to
make a generic undo.

But  I guess I could write a more specific undo for the data I am
storing.   That would be pretty easy.  Thanks for your help.

PS.  Sorry I picked the wrong list.

Hi Douglas,
     I am confused a bit... are you working on some generic undo
capabilies built into the treeview widget ? (doesnt make sence
to me).

My guess is that you are writing an application that should have
undo/redo ... and some treeview.

For the record, this list is reserved for discussions about developing
the gtk+ toolkit itself, questions about writing your gtk+ application
should be asked on gtk-app-devel-list gnome org

     My opinion on this matter is that mixing the treeview and undo/redo
logic is a confusing flaw, you need an infrastructure to undo/redo some
actions that the user has performed on the dataset that your particular
application is supposed to manage, when these actions are executed/reversed
(undo/redo), then your treemodel should be updated so that the user
sees the up-to-date data.
