菜鸟求助 关于 TCnCheckTreeView组件
最近用了一下TCnCheckTreeView组件,刚开始看了一下Demo感觉会用了,可是到了实际中就发现问题重重
我想给TCnCheckTreeView组件的结点赋值,总是报错
例如如下的树形
-aaa
---aaa1
---aaa2
-bbb
----bbb1
--------bbb11
我用的是
ctv1.Checked[ctv1.Items[
0
]]:=True;
ctv1.Checked[ctv1.Items[
0
].Item[0]]:=False;
ctv1.Checked[ctv1.Items[
0
].Item[1]]:=True;报错了
不知道这样用对不对啊 给点例子也成

在D7下按楼主这样的节点结构与代码尝试了一下没有错误。
建议楼主在赋值Checked之前,检查一下传入的NODE是否是nil?
