c++ - 如何在 C++ Win32 应用程序中创建 Windows 风格的文本框

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;
}

我使用:

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心边框文本框。

如何创建 windows 风格的文本框(带有 3D 淡蓝色边框)？

不使用 CreateWindow，而是使用 CreateWindowEx 并指定 WS_EX_CLIENTEDGE 作为第一个参数。

您可以使用 Visual Studio 附带的 Spy++ 工具将您创建的编辑控件的样式与常用控件(例如，当您在资源管理器中显示“属性”时)进行比较。
