C# CefWebBrowser不';我没有出现

C# CefWebBrowser不';我没有出现,c#,winforms,webbrowser-control,chromium,chromium-embedded,C#,Winforms,Webbrowser Control,Chromium,Chromium Embedded,解决方案: private void Create() { var page = new TabPage("New Tab"); page.Padding = new Padding(0, 0, 0, 0); var browser = new CefWebBrowser(); browser.StartUrl = startUrl; browser.Dock

解决方案:

private void Create()
        {
            var page = new TabPage("New Tab");
            page.Padding = new Padding(0, 0, 0, 0);

            var browser = new CefWebBrowser();
            browser.StartUrl = startUrl;
            browser.Dock = DockStyle.Fill;
            browser.TitleChanged += (s, e) =>
            {
                BeginInvoke(new Action(() =>
                {
                    var title = browser.Title;
                    if (tabControl.SelectedTab == page)
                    {
                        Text = browser.Title + " - " + _mainTitle;
                    }
                    page.ToolTipText = title;
                    if (title.Length > 18)
                    {
                        title = title.Substring(0, 18) + "...";
                    }
                    page.Text = title;
                }));
            };
            browser.AddressChanged += (s, e) =>
            {
                BeginInvoke(new Action(() =>
                {
                    addressTextBox.Text = browser.Address;
                }));
            };
            browser.StatusMessage += (s, e) =>
            {
                BeginInvoke(new Action(() =>
                {
                    statusLabel.Text = e.Value;
                }));
            };

            page.Controls.Add(browser);

            tabControl.TabPages.Add(page);

            tabControl.SelectedTab = page;
        }
此问题是由于未在Program.cs中加载CEF运行时造成的。只需将示例文件中的所有代码复制到Program.cs

然后,如果您的CefWebBrowser被卡住并且有“旋转等待鼠标光标”,则将SingleProcess设置为true

原因是,如果从已识别的辅助进程调用浏览器,整个进程将被阻止,直到进程结束


问题:

private void Create()
        {
            var page = new TabPage("New Tab");
            page.Padding = new Padding(0, 0, 0, 0);

            var browser = new CefWebBrowser();
            browser.StartUrl = startUrl;
            browser.Dock = DockStyle.Fill;
            browser.TitleChanged += (s, e) =>
            {
                BeginInvoke(new Action(() =>
                {
                    var title = browser.Title;
                    if (tabControl.SelectedTab == page)
                    {
                        Text = browser.Title + " - " + _mainTitle;
                    }
                    page.ToolTipText = title;
                    if (title.Length > 18)
                    {
                        title = title.Substring(0, 18) + "...";
                    }
                    page.Text = title;
                }));
            };
            browser.AddressChanged += (s, e) =>
            {
                BeginInvoke(new Action(() =>
                {
                    addressTextBox.Text = browser.Address;
                }));
            };
            browser.StatusMessage += (s, e) =>
            {
                BeginInvoke(new Action(() =>
                {
                    statusLabel.Text = e.Value;
                }));
            };

            page.Controls.Add(browser);

            tabControl.TabPages.Add(page);

            tabControl.SelectedTab = page;
        }
有没有人有在WinForm中使用CEF(Chromium Embedded Framework)的经验

这个部件折磨了我一整天。我不能让它工作。 它只是没有出现

所以我的问题是:如何在WinForm应用程序中使用CEF

我确实查看了论坛,但令人惊讶的是没有人问这个问题。 看来我是唯一一个不知道如何使用它的哑巴

public partial class Form1 : Form
{
    private CefWebBrowser cefwbShell = null;
    //private readonly SynchronizationContext _pUIThread;

    private void Form1_Load(object sender, EventArgs e)
    {
        cefwbShell.Visible = true;
        cefwbShell = new CefWebBrowser { StartUrl = "http://example.com" };
        cefwbShell.Parent = this;
        cefwbShell.Dock = DockStyle.Fill;
        cefwbShell.BringToFront();
        cefwbShell.Show();
    }
}

            page.Padding = new Padding(0, 0, 0, 0);

更新2:

            page.Padding = new Padding(0, 0, 0, 0);

            tabControl.SelectedTab = page;
        }

您从未将控件添加到表单的控件集合中,至少在您显示的示例中是这样。

我在启动浏览器时也遇到了问题。我可以加载所有CEF DLL,但浏览器不会显示!我得到的只是在控件上方悬停时旋转的等待鼠标光标

不幸的是,我还没有找到问题的根源,但由于示例项目CefGlue.Client有效,我只是将其复制到我的解决方案中

另外,我看不出您是如何初始化CEF运行时的。看看CefGlue.Client中的Program.cs是如何完成的,但基本上是这样的:

    [STAThread]
    private static int Main(string[] args)
    {
        try
        {
            CefRuntime.Load();
        }
        catch (DllNotFoundException ex)
        {
            MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
            return 1;
        }
        catch (CefRuntimeException ex)
        {
            MessageBox.Show(ex.Message, "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
            return 2;
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.ToString(), "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
            return 3;
        }

        var mainArgs = new CefMainArgs(args);
        var app = new DemoApp();

        var exitCode = CefRuntime.ExecuteProcess(mainArgs, app);
        if (exitCode != -1)
            return exitCode;

        var settings = new CefSettings
            {
                // BrowserSubprocessPath = @"D:\fddima\Projects\Xilium\Xilium.CefGlue\CefGlue.Demo\bin\Release\Xilium.CefGlue.Demo.exe",
                SingleProcess = false,
                MultiThreadedMessageLoop = true,
                LogSeverity = CefLogSeverity.Disable,
                LogFile = "CefGlue.log",
            };

        CefRuntime.Initialize(mainArgs, settings, app);

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        if (!settings.MultiThreadedMessageLoop)
        {
            Application.Idle += (sender, e) => { CefRuntime.DoMessageLoopWork(); };
        }

        Application.Run(new MainForm());

        CefRuntime.Shutdown();
        return 0;
    }

您不应该在生产中使用
SingleProcess
,您实际上可以离开多进程模式(
SingleProcess=false
),但需要这样做,并且您不会有调试问题(旋转等待光标)

我也有同样的问题,我通过修改“BrowserSubprocessPath”解决了它,情况如下:

        //var browserProcessPath = CombinePaths(localFolder, "..", "..", "..",
        //    "CefGlue.Demo.WinForms", "bin", "Release", "Xilium.CefGlue.Demo.WinForms.exe");

        var browserProcessPath = CombinePaths(localFolder, "Xilium.CefGlue.Demo.WinForms.exe");

        var settings = new CefSettings
        {
            BrowserSubprocessPath = browserProcessPath,
            SingleProcess = false,
            MultiThreadedMessageLoop = true,
            LogSeverity = CefLogSeverity.Disable,
            LogFile = "CefGlue.log",
        };
因为我更改了应用程序输出目录,所以“browserProcessPath”无效,所以我修改了“browserProcessPath”以匹配输出目录,以便应用程序可以找到它


但是,我仍然无法理解“browserProcessPath”的含义和用法。

?7小时后没有回复?……请有人帮忙……ayaya~~没有人没有人la~~~我确实将CefBrowser添加到tabPage组件中,然后将其添加到tabControl中,tabControl已添加到WinForm的控件集合中。看到我的最新代码嗨圣代,非常感谢!我已经解决了这个问题。是,这是由于未在Program.cs中加载CEF运行时造成的。我也解决了你的问题,那就是“旋转等待鼠标光标”。这是因为SingleProcess被设置为false,因此如果从已识别的辅助进程调用浏览器,它将阻止整个进程,直到退出为止。因此,请在我的帖子中查看解决方案。但出于礼貌,我会把你的帖子标记为答案,因为你是唯一提供相关解决方案的人^^^干杯谢谢你,弗兰瓦!我会试试你的解决办法。RegardS关于在你的应用中初始化CEF的详细信息,你可以在这里找到:尽管在Mac throuh Xilium.CefGlue上,它目前只是运行模式(SingleProcess=true),只是注意到存在平台差异。
