获取树状视图中的选定项目 [英] Get selected item in treeview

问题描述

我有一个用WinApi函数用C ++编写的程序(我没有使用MFC).在此程序中，我有一个树状视图(可以添加或删除元素)，并且我想解决一个问题:我想确切地知道选择了哪个项目.请帮忙.

示例:

I have a program written in C++ with WinApi functions (I am not using MFC). In this program I have a treeview (elements can be added or deleted) and I want to solve a problem: I want to know exactly which item was selected. Please help.

Example:

+Color
 -Red
 -Blue
+Ground
 -sldfs
 -sdfsdfafsd

返回值:红色(或其他颜色)

Return: Color red (or something else)

推荐答案

类似这样的东西

Something like this

// Get a handle to the selected item
HTREEITEM hSelectedItem = TreeView_GetSelection(hwnd);

if (hSelectedItem == NULL) // Nothing selected
    return;

// Now get the text of the selected item
TCHAR buffer[128];

TVITEM item;
item.hItem = hSelectedItem;
item.mask = TVIF_TEXT;
item.cchTextMax = 128;
item.pszText = buffer;
if (TreeView_GetItem(hwnd, &item))
{
    cout << item.pszText << " is selected" << endl;
}
