Question

我不知道这个主题的主题是否有意义。我正在努力尝试CEF3。我刚开始使用C ++而且我很难过。对不起。

初始目标是按照本主题中的说明使弹出窗口全屏显示：http://www.magpcss.org/ceforum/viewtopic.php?f=10&t=11706

我也认为这是一种更好的方法：http://magpcss.org/ceforum/viewtopic.php?f=6&t=10772。但是，没有充分的解释。您认为需要在下面的代码段中添加什么才能使浏览器在基于WINAPI的窗口中运行。

#include <windows.h>
// Source taken here: http://www.winprog.org/tutorial/simple_window.html

const char g_szClassName[] = "MultiscreenProject";

// Step 4: the Window Procedure
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
    switch(msg) {
        case WM_CLOSE:
            DestroyWindow(hwnd);
        break;

        case WM_DESTROY:
            PostQuitMessage(0);
        break;

        default:
            return DefWindowProc(hwnd, msg, wParam, lParam);
    }
    return 0;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {

    WNDCLASSEX wc;
    HWND hwnd;
    MSG Msg;

    //Full-screen mode
    RECT desktop;

    // Get a handle to the desktop window
    const HWND hDesktop = GetDesktopWindow();

    // Get the size of screen to the variable desktop
    GetWindowRect(hDesktop, &desktop);

    // The top left corner will have coordinates (0,0)
    // and the bottom right corner will have coordinates
    // (horizontal, vertical)
    int horizontal = desktop.right;
    int vertical = desktop.bottom;

    //Step 1: Registering the Window Class
    wc.cbSize        = sizeof(WNDCLASSEX);
    wc.style         = 0;
    wc.lpfnWndProc   = WndProc;
    wc.cbClsExtra    = 0;
    wc.cbWndExtra    = 0;
    wc.hInstance     = hInstance;
    wc.hIcon         = LoadIcon(NULL, IDI_APPLICATION);
    wc.hCursor       = LoadCursor(NULL, IDC_ARROW);
    wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
    wc.lpszMenuName  = NULL;
    wc.lpszClassName = g_szClassName;
    wc.hIconSm       = LoadIcon(NULL, IDI_APPLICATION);

    if( !RegisterClassEx(&wc) ) {
        MessageBox( NULL, "Window Registration Failed!", "Error!", MB_ICONEXCLAMATION | MB_OK );
        return 0;
    }

    hwnd = CreateWindowEx(
        0,
        g_szClassName,
        "Multiscreen Project",
        WS_POPUP,
        CW_USEDEFAULT, CW_USEDEFAULT, horizontal, vertical,
        NULL, NULL, hInstance, NULL
    );

    if( hwnd == NULL ){
        MessageBox( NULL, "Window Creation Failed!", "Error!", MB_ICONEXCLAMATION | MB_OK );
        return 0;
    }

    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

    // Step 3: The Message Loop
    while( GetMessage(&Msg, NULL, 0, 0) > 0 ) {
        TranslateMessage(&Msg);
        DispatchMessage(&Msg);
    }
    return Msg.wParam;
}

非常感谢。

我想你需要这样做：

创建CefApp和CefMainArgs
创建CefSettings
init CEF：CefInitialize()
通过WinAPI创建窗口
创建CefClient
使用您窗口的HWND创建CefWindowInfo
调用CefBrowserHost::CreateBrowser()＆lt; - 将CEF绑定到窗口
显示您的窗口

不要忘记将CEF消息的循环集成到您应用的WndProc中：Message_Loop_Integration

CEF3与WINAPI
