如何设置CTreeCtrl的风格?

[buptwaitme2002]

我是在切割视图中使用,如何设置CTreeCtrl使得CTreeView可以有+和连线之类的

[tayshaun]

OnCreate中设置style，比如：
lpCreateStruct->style |= TVS_HASLINES | TVS_LINESATROOT
| TVS_SHOWSELALWAYS | TVS_HASBUTTONS | TVS_EDITLABELS;

[phoenix96_2000]

GetTreeCtrl().ModifyStyle(0,TVS_HASBUTTONS | TVS_LINESATROOT | TVS_HASLINES);
