Is this possible?
Yes. I did this a while back, but would need to find an archive to
provide you with exact code.
I have a (for example) a grid which contains
Various action widgets
And a Treeview based on a liststore
Is there any way to make sure that the changes made to a cell in the
liststore are "committed" if I click on one of the other widgets
I cant find anything to do this and if I leave the cell without pressing
enter or clicking on another cell, all changes are lost
Connect to the GtkCellRenderer "editing-started" signal. In that
callback, you will have an GtkEntry (GtkCellEditable) object. Connect to
the Entry's "changed" signal and keep a permanent string around with the
text the user is typing. Also preserve the path and column being edited
(obtained with "editing-started").
Also connect to GtkCellRenderer "editing-canceled" signal. In this
callback, use the path, column, and text you retained from
"editing-started", and update the ListStore.
thanks
Mike
