如何用C++代码创建tabcontrol

TabControl 是 Windows 窗体控件之一，用于显示多个选项卡，每个选项卡可以包含不同的控件。下面是一个简单的 C++ 代码示例，用于创建一个包含两个选项卡的 TabControl：

#include <windows.h>
#include <commctrl.h>

#pragma comment(lib, "comctl32.lib")

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    PSTR szCmdLine, int iCmdShow)
{
    static TCHAR szAppName[] = TEXT("TabControl");
    HWND hwnd;
    MSG msg;
    WNDCLASS wndclass;

    // 注册窗口类
    wndclass.style = CS_HREDRAW | CS_VREDRAW;
    wndclass.lpfnWndProc = WndProc;
    wndclass.cbClsExtra = 0;
    wndclass.cbWndExtra = 0;
    wndclass.hInstance = hInstance;
    wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
    wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    wndclass.lpszMenuName = NULL;
    wndclass.lpszClassName = szAppName;

    if (!RegisterClass(&wndclass))
    {
        MessageBox(NULL, TEXT("This program requires Windows NT!"),
            szAppName, MB_ICONERROR);
        return 0;
    }

    // 创建主窗口
    hwnd = CreateWindow(szAppName, TEXT("TabControl Demo"),
        WS_OVERLAPPEDWINDOW | WS_CLIPCHILDREN,
        CW_USEDEFAULT, CW_USEDEFAULT,
        400, 300, NULL, NULL, hInstance, NULL);

    // 创建 TabControl
    HWND hwndTab = CreateWindowEx(0, WC_TABCONTROL, NULL,
        WS_CHILD | WS_VISIBLE,
        0, 0, 400, 300,
        hwnd, NULL, hInstance, NULL);

    // 添加选项卡
    TCITEM tie;
    tie.mask = TCIF_TEXT;
    tie.pszText = TEXT("Tab 1");
    TabCtrl_InsertItem(hwndTab, 0, &tie);

    tie.pszText = TEXT("Tab 2");
    TabCtrl_InsertItem(hwndTab, 1, &tie);

    // 显示窗口
    ShowWindow(hwnd, iCmdShow);
    UpdateWindow(hwnd);

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

    return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)
    {
    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;

    default:
        return DefWindowProc(hwnd, message, wParam, lParam);
    }
}

在上面的代码中，首先注册一个窗口类，然后创建一个主窗口和一个 TabControl。接下来，添加两个选项卡到 TabControl 中，并启动消息循环以等待用户交互。当用户关闭窗口时，程序会发送 WM_DESTROY 消息，退出应用程序。
