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 ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list

Re: Force liststore to update when leaving treeview
One idea is to hook the widget to the "leave-notify-event", which will be triggered when the mouse leaves the widget.
