问题描述

我在MFC应用程序的运行时创建了一个树视图，我已经添加了几个节点，现在我想做一些点击节点的东西，所以我可以得到树视图的点击事件？

I have created a treeview at runtime in MFC application , I have added few nodes to it now i want to do some stuff on click of nodes so how i can get click event of treeview ?

我的代码看起来像这样：

My code looks like this :

CTreeCtrl *m_ctlTreeview;
m_ctlTreeview = new CTreeCtrl ;
m_ctlTreeview->Create(WS_CHILD | WS_VISIBLE | WS_BORDER | WS_TABSTOP |
                 TVS_HASLINES | TVS_HASBUTTONS | TVS_LINESATROOT |
         TVS_SINGLEEXPAND | TVS_SHOWSELALWAYS |  
         TVS_TRACKSELECT,
                 CRect(25, 60, 385, 260), this, 0x1221);


hparentitem = m_ctlTreeview->InsertItem("Parent",TVI_ROOT);
m_ctlTreeview->InsertItem("Child", hparentitem);

推荐答案

一个选项是为通知消息添加处理程序在设计时使用消息映射中的 ON_NOTIFY ，为该子窗口ID（在您的示例中为0x1221）设置为父类。

One option is to add a handler for the notification messages for that child window ID (0x1221 in your example) to the parent class at design time using ON_NOTIFY in the message map as usual. If there are no messages, the handler won't be triggered.

或者，您可以添加一个通用 WM_NOTIFY 处理程序到具有 ON_MESSAGE 的父窗口的消息映射，然后检查消息是否来自您的新树控件。

Alternatively, you could add a generic WM_NOTIFY handler to the message map of the parent window with ON_MESSAGE, and then check to see if the message comes from your new tree control.
