Defined in:Adds an item to the end of a tree.
void AppendTreeItem(TreeItemWidget *item);
|The item to add to the tree.
AppendTreeItem function adds an item to the end of a tree at the top level of the hierarchy.
Note that unless that
kListItemsEnabled flag has been set with the
ListWidget::SetListFlags function, the item added to the tree is disabled before the
AppendTreeItem function returns so that clicks go through to the tree widget. To allow an item in a tree or any of its subwidgets to receive events, call the
Widget::EnableWidget function for that item after adding it to the tree.
