如何使用其句柄更改窗口所有者

#include<Windows.h>
#include<iostream>

BOOL SetNewWindowOwner(HWND hWnd, HWND hWndNewOwner)
{
    // 获取窗口的当前所有者
    HWND hWndOwner = GetWindow(hWnd, GW_OWNER);

    // 如果新的所有者与当前所有者相同，则不执行任何操作
    if (hWndOwner == hWndNewOwner)
        return TRUE;

    // 设置新的窗口所有者
    LONG_PTR result = SetWindowLongPtr(hWnd, GWLP_HWNDPARENT, (LONG_PTR)hWndNewOwner);

    // 检查结果
    if (result == 0)
    {
        std::cerr << "SetWindowLongPtr failed with error code: "<< GetLastError()<< std::endl;
        return FALSE;
    }

    return TRUE;
}

int main()
{
    // 创建一个顶级窗口
    HWND hWnd = CreateWindowEx(0, "MyWindowClass", "My Window", WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
        NULL, NULL, NULL, NULL);

    // 创建一个新的窗口所有者
    HWND hWndNewOwner = CreateWindowEx(0, "MyWindowClass", "New Owner Window", WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
        NULL, NULL, NULL, NULL);

    // 更改窗口所有者
    if (!SetNewWindowOwner(hWnd, hWndNewOwner))
    {
        std::cerr << "Failed to set new window owner"<< std::endl;
        return 1;
    }

    // 处理窗口消息
    MSG msg = { 0 };
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return 0;
}
