Making a tabbed cef sharp browser rename tab page

Question

i have been creating a cefsharp browser in C#. i have made it so you can have multiple tabs and it loads the pages correctly. however, i cannot seem to find how i can rename the tab to the name of the page.

this is the code in the load event for form1.cs:

                    Cef.Initialize();
        toolTip1.SetToolTip(button1, "Settings");
        TabPage tab = new TabPage();
        Tab newtab = new Tab();
        newtab.Show();
        newtab.TopLevel = false;
        newtab.Dock = DockStyle.Fill;
        tab.Controls.Add(newtab);
        tabControl1.TabPages.Add(tab);

i have tried:

                    private void myBrowser_isLoading(object sender) 
    {
        myBrowser.Parent.Parent.Text = myBrowser.Title;
    }

but that doesn't work.

then this is the code for tab.cs:

                    public Tab()
    {
        InitializeComponent();
        // Start the browser after initialize global component
        InitializeChromium();

    }
    public CefSharp.WinForms.ChromiumWebBrowser myBrowser;
    public bool nav = new bool();
    public void InitializeChromium()
    {


         myBrowser = new CefSharp.WinForms.ChromiumWebBrowser("http://www.google.com");
        this.Controls.Add(myBrowser);
        myBrowser.Dock = DockStyle.Fill;

        myBrowser.Parent = panel2;
    if (nav == true)
        {
            myBrowser.Load(textBox1.Text);
            nav = false;
        }



    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        Cef.Shutdown();

    }

again, i am using c# with the latest build of cef sharp(or atleast the one installed from the nuget package manager).

Answer 1

In your tab function in form1.cs, you need to add a title changed function like this

browser.TitleChanged += OnBrowserTitleChanged;

you also need to specify what browser is and set dockstyle to fill like this

ChromiumWebBrowser browser = new ChromiumWebBrowser("google.com");
tab.Controls.Add(browser);
browser.Dock = DockStyle.Fill;

now for the OnBrowserTitleChanged, you will need an EventArg which will tell the tab to have the document title in this format

this.InvokeOnUiThreadIfRequired(() => browserTabControl.SelectedTab.Text = args.Title);

this will add the document title to the tabcontrol browserTabControl is the name of the tabcontrol you will have to change browserTabControl to whatever name you have for the tabcontrol. Also the code you have does not belong with cef initialize. you need to create an addNewTab method with all the functions that will be processed when you want to add a new tab. Also, you cannot use a panel if you want to have tabs. you need a tabcontrol
