如何在C++ Win32应用程序中创建Windows样式的文本框

Question

我试过这个:

#include <windows.h>

#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")

LRESULT CALLBACK WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam);

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR nCmdLine, int nCmdShow)
{
    LPTSTR windowClass = TEXT("WinApp");
    LPTSTR windowTitle = TEXT("Windows Application");
    WNDCLASSEX wcex;

    wcex.cbClsExtra = 0;
    wcex.cbSize = sizeof(WNDCLASSEX);
    wcex.cbWndExtra = 0;
    wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
    wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
    wcex.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    wcex.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
    wcex.hInstance = hInstance;
    wcex.lpfnWndProc = WndProc;
    wcex.lpszClassName = windowClass;
    wcex.lpszMenuName = NULL;
    wcex.style = CS_HREDRAW | CS_VREDRAW;
    if (!RegisterClassEx(&wcex))
    {
        MessageBox(NULL, TEXT("RegisterClassEx Failed!"), TEXT("Error"), MB_ICONERROR);
        return EXIT_FAILURE;
    }

    HWND hWnd;

    if (!(hWnd = CreateWindow(windowClass, windowTitle, WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, NULL, NULL, hInstance, NULL)))
    {
        MessageBox(NULL, TEXT("CreateWindow Failed!"), TEXT("Error"), MB_ICONERROR);
        return EXIT_FAILURE;
    }

    HWND hWndEdit = CreateWindow(TEXT("Edit"), TEXT("test"), WS_CHILD | WS_VISIBLE | WS_BORDER, 100, 20, 140, 20, hWnd, NULL, NULL, NULL);

    ShowWindow(hWnd, nCmdShow);
    UpdateWindow(hWnd);

    MSG msg;

    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    return EXIT_SUCCESS;
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch (msg)
    {
    case WM_DESTROY:
        PostQuitMessage(EXIT_SUCCESS);
    default:
        return DefWindowProc(hWnd, msg, wParam, lParam);
    }
    return FALSE;
}

我用:

CreateWindow(TEXT("Edit"), TEXT("test"), WS_CHILD | WS_VISIBLE | WS_BORDER, 100, 20, 140, 20, hWnd, NULL, NULL, NULL); 

创建一个文本框,它只是一个丑陋的黑色实体边框文本框.

如何创建一个Windows风格的文本框(带有浅蓝色边框)？

Answer 1

而不是使用CreateWindow,使用CreateWindowEx和指定WS_EX_CLIENTEDGE作为第一个参数.

您可以使用Visual Studio附带的Spy ++工具将创建的编辑控件的样式与库存样式进行比较(例如,当您在资源管理器中的文件上显示"属性"时).

OP 编辑​​了他的问题，删除了原始代码，因此使答案无效，说：

这是创建带有文本框的窗口的简单示例。

我将其回滚以恢复原始代码，但我认为工作示例很好，所以这里是：

#include <windows.h>

#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0'processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*' \"")

LRESULT CALLBACK WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam);

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                     LPSTR nCmdLine，int nCmdShow）
{
  LPTSTR windowClass = TEXT("WinApp");
  LPTSTR windowTitle = TEXT("Windows 应用程序");
  WNDCLASSEX wcex；

  wcex.cbClsExtra = 0;
  wcex.cbSize = sizeof(WNDCLASSEX);
  wcex.cbWndExtra = 0;
  wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
  wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
  wcex.hIcon = LoadIcon(NULL, IDI_APPLICATION);
  wcex.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
  wcex.hInstance = hInstance;
  wcex.lpfnWndProc = WndProc;
  wcex.lpszClassName = 窗口类;
  wcex.lpszMenuName = NULL;
  wcex.style = CS_HREDRAW | CS_VREDRAW；
  if (!RegisterClassEx(&wcex))
  {
    MessageBox(NULL, TEXT("RegisterClassEx 失败！"), TEXT("错误"),
               MB_ICONERROR);
    返回 EXIT_FAILURE；
  }

  HWND hWnd;

  if (!(hWnd = CreateWindow(windowClass, windowTitle, WS_OVERLAPPEDWINDOW,
                            CW_USEDEFAULT，CW_USEDEFAULT，CW_USEDEFAULT，
                            CW_USEDEFAULT、NULL、NULL、hInstance、NULL）））
  {
    MessageBox(NULL, TEXT("创建窗口失败！"), TEXT("错误"), MB_ICONERROR);
    返回 EXIT_FAILURE；
  }

  HWND hWndEdit = CreateWindowEx(WS_EX_CLIENTEDGE, TEXT("编辑"), TEXT("测试"),
                               WS_CHILD | WS_CHILD WS_VISIBLE, 100, 20, 140,
                               20、hWnd、NULL、NULL、NULL）；

  ShowWindow(hWnd, nCmdShow);
  更新窗口（hWnd）；

  味精味精；

  while (GetMessage(&msg, NULL, 0, 0))
  {
    翻译消息(&msg);
    调度消息(&msg);
  }
  返回退出_成功；
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
  开关（消息）
  {
  案例 WM_DESTROY：
    PostQuitMessage(EXIT_SUCCESS);
  默认：
    返回 DefWindowProc(hWnd, msg, wParam, lParam);
  }
  返回假；
}
