我一直用这写在单击消息中,老是得到前一个选中项的数据
弄了好几天,查了好多资料都不行,连MFC我的复制过来还是不行,晕死了.
最后在网上找了好久才找到要单击要用鼠标坐标来判断,用TreeView_HitTest()宏,
这他妈的从哪知道呀.
void MyAppClass::OnCloickTree(LPNMHDR param1){ TVHITTESTINFO thti; HTREEITEM htItem; TVITEM tvi; POINT point; GetCursorPos(&point); ScreenToClient(hTree, &point); thti.pt = point; thti.flags = TVHT_TORIGHT; htItem = TreeView_HitTest(hTree, &thti); if (htItem == NULL) return; TCHAR szText[20]; memset(&tvi, 0, sizeof(tvi)); tvi.mask = TVIF_TEXT | TVIF_PARAM; tvi.hItem = htItem; tvi.pszText = szText; tvi.cchTextMax = sizeof(szText); TreeView_GetItem(hTree, &tvi); SetDlgItemText(win_hWnd, IDC_EDIT1, szText); }
以上都在vs2017中测试通过
