示例1: Prepare

        private void Prepare(ListBox target)
        {
            // The ListBox needs to be part of a rooted visual tree.
            var root = new TestRoot();
            root.Child = target;

            // Apply the template to the ListBox itself.
            target.ApplyTemplate();

            // Then to its inner ScrollViewer.
            var scrollViewer = (ScrollViewer)target.GetVisualChildren().Single();
            scrollViewer.ApplyTemplate();

            // Then make the ScrollViewer create its child.
            ((ContentPresenter)scrollViewer.Presenter).UpdateChild();

            // Now the ItemsPresenter should be reigstered, so apply its template.
            target.Presenter.ApplyTemplate();

            // Because ListBox items are virtualized we need to do a layout to make them appear.
            target.Measure(new Size(100, 100));
            target.Arrange(new Rect(0, 0, 100, 100));

            // Now set and apply the item templates.
            foreach (ListBoxItem item in target.Presenter.Panel.Children)
            {
                item.Template = ListBoxItemTemplate();
                item.ApplyTemplate();
                item.Presenter.ApplyTemplate();
                ((ContentPresenter)item.Presenter).UpdateChild();
            }

            // The items were created before the template was applied, so now we need to go back
            // and re-arrange everything.
            foreach (IControl i in target.GetSelfAndVisualDescendents())
            {
                i.InvalidateMeasure();
            }

            target.Arrange(new Rect(0, 0, 100, 100));
