如何在win32中增加ListBox的边框/框架宽度

#include <windows.h>

// 自定义的ListBox控件类
class CustomListBox : public ListBox
{
public:
    CustomListBox()
    {
    }

protected:
    // 重写WM_NCCALCSIZE消息的处理函数
    virtual LRESULT OnNcCalcSize(WPARAM wParam, LPARAM lParam)
    {
        // 调用父类的消息处理函数
        LRESULT result = ListBox::OnNcCalcSize(wParam, lParam);

        // 获取非客户区矩形
        LPNCCALCSIZE_PARAMS params = reinterpret_cast<LPNCCALCSIZE_PARAMS>(lParam);
        RECT& ncRect = params->rgrc[0];

        // 增加边框/框架的宽度
        int borderWidth = 2; // 设置边框宽度为2个像素
        ncRect.left -= borderWidth;
        ncRect.top -= borderWidth;
        ncRect.right += borderWidth;
        ncRect.bottom += borderWidth;

        return result;
    }
};

// 窗口过程函数
LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    switch (uMsg)
    {
        case WM_CREATE:
        {
            // 创建自定义的ListBox控件
            CustomListBox* listBox = new CustomListBox();
            listBox->Create(hwnd, WS_CHILD | WS_VISIBLE | WS_BORDER | LBS_STANDARD, 10, 10, 200, 150);
            break;
        }
        case WM_DESTROY:
        {
            // 释放自定义的ListBox控件
            CustomListBox* listBox = reinterpret_cast<CustomListBox*>(GetWindowLongPtr(hwnd, GWLP_USERDATA));
            delete listBox;
            break;
        }
        default:
            return DefWindowProc(hwnd, uMsg, wParam, lParam);
    }

    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    // 注册窗口类
    WNDCLASS wc = {};
    wc.lpfnWndProc = WindowProc;
    wc.hInstance = hInstance;
    wc.lpszClassName = L"CustomListBoxClass";
    RegisterClass(&wc);

    // 创建窗口
    HWND hwnd = CreateWindowEx(0, L"CustomListBoxClass", L"Custom ListBox", WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT, 400, 300, nullptr, nullptr, hInstance, nullptr);

    // 显示窗口
    ShowWindow(hwnd, nCmdShow);

    // 消息循环
    MSG msg = {};
    while (GetMessage(&msg, nullptr, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return 0;
}
