c++ - CTreeCtrl状态图片限制为15张图片

Question

我有一个 CTreeCtrl，它使用“状态图像”在普通图标旁边获得第二个图标。来自此处的文档 http://msdn.microsoft.com/en-us/library/fc4e6etb(v=vs.80).aspx :

If a state image list is specified, a tree control reserves space to the left of each item's icon for a state image. An application can use state images, such as checked and cleared check boxes, to indicate application-defined item states. A nonzero value in bits 12 through 15 specifies the one-based index of a state image (0 indicates no state image).

由于只有 4 位，并且保留 0 表示没有状态图像，所以只能有 15 个状态图像。这里也提到了这一点:http://www.codeguru.com/cpp/controls/treeview/usingimages/article.php/c669

问题我已经用完了所有 15 个状态图标，还想添加更多。我有哪些选择可以实现这一目标？

实现自定义绘制的 TreeView 或找到这样的实现。
