For an introduction to TreeModels, read: http://www.mono-project.com/GtkSharp_TreeView_Tutorial A custom tree model could be a better approach here especially if you want to have your model editable and keep the edited data in sync with your objects: http://www.mono-project.com/ImplementingGInterfaces The examples in the Gtk# SVN repo are always worth looking at, too. > protected void FillTreeView() > { > // Loop through the tasks and add them to the store > foreach(TaskEntry task in _rootTaskEntry.Children) > { > Gtk.TreeIter taskIter = > _outlineTreeStore.AppendValues(task); > FillTreeView(taskIter, task); > } > } > > protected void FillTreeView(TreeIter taskIter, TaskEntry task) > { > foreach(TaskEntry childTask in task.Children) > { > TreeIter newIter = > _outlineTreeStore.AppendValues(taskIter, childTask); > FillTreeView(newIter, childTask); > } > } > > _______________________________________________ Gtk-sharp-list maillist - Gtk-sharp-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/gtk-sharp-list
