我使用CefSharp來創建瀏覽器。它正在工作，我可以通過使用新標籤導航到各種網站。但是，當我點擊以前的標籤時，地址欄中的所有標籤都顯示相同的URL，並且它們都具有完全相同的標題。這裏是我的代碼：如何使用正確的地址和標題更改在CefSharp中實現新選項卡？
private void FormBrowser_Load(object sender, EventArgs e)
{
CefSettings settings = new CefSettings();
Cef.Initialize(settings);
ChromiumWebBrowser browser = new ChromiumWebBrowser(toolStripTextBoxAddress.Text);
browser.Parent = tabControl.SelectedTab;
browser.Dock = DockStyle.Fill;
browser.AddressChanged += Browser_AddressChanged;
browser.TitleChanged += Browser_TitleChanged;
}
// new tab function
public void addNewTab()
{
TabPage tpage = new TabPage();
tpage.Text = "New Tab";
tabControl.Controls.Add(tpage);
tabControl.SelectTab(tabControl.TabCount - 1);
toolStripTextBoxAddress.Text = "";
ChromiumWebBrowser browser = new ChromiumWebBrowser(toolStripTextBoxAddress.Text);
browser.Parent = tpage;
browser.Dock = DockStyle.Fill;
browser.AddressChanged += Browser_AddressChanged;
browser.TitleChanged += Browser_TitleChanged;
}
private void Browser_TitleChanged(object sender, TitleChangedEventArgs e)
{
this.Invoke(new MethodInvoker(() =>
{
tabControl.SelectedTab.Text = e.Title;
}));
}
private void Browser_AddressChanged(object sender, AddressChangedEventArgs e)
{
this.Invoke(new MethodInvoker(() =>
{
toolStripTextBoxAddress.Text = e.Address;
}));
}
// navigate method
private void toolStripTextBoxAddress_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
if (!string.IsNullOrEmpty(toolStripTextBoxAddress.Text))
{
if (!toolStripTextBoxAddress.Text.Contains("."))
{
getCurrentBrowser().Load("http://www.google.com/search?q=" + toolStripTextBoxAddress.Text);
}
else
{
getCurrentBrowser().Load(toolStripTextBoxAddress.Text);
}
}
}
}
// get current browser
private ChromiumWebBrowser getCurrentBrowser()
{
return (ChromiumWebBrowser)tabControl.SelectedTab.Controls[0];
}
// new tab button
private void toolStripButtonNewTab_Click(object sender, EventArgs e)
{
addNewTab();
}
這裏是我曾嘗試：
private void tabControl_SelectedIndexChanged(object sender, EventArgs e)
{
ChromiumWebBrowser currentBrowser = getCurrentBrowser();
toolStripTextBoxAddress.Text = currentBrowser.Address;
}
當我嘗試打開一個新的標籤它給我在這一行錯誤return (ChromiumWebBrowser)tabControl.SelectedTab.Controls[0];
如何我解決了這個問題？提前致謝。
