由于某种原因,即使它在最顶层和Activate()上打开,我的表单也不会始终聚焦;和焦点();和BringToFront();都被称为。
程序和源代码: sites.google.com/site/windowsprogramfortranslation /
我在所有这些地方添加了所有这些内容,但Google翻译的形式和文本框仍未被选中
void FormMain_Shown(object sender, EventArgs e)
{
BringToFront();
webBrowserMain.Focus();
panelMain.Enabled = false;
Focus();
panelMain.Enabled = true;
Activate();
webBrowserMain.Select();
webBrowserMain.Focus();
}
void webBrowserMain_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if (webBrowserMain.ReadyState == WebBrowserReadyState.Complete)
{
this.Activate();
webBrowserMain.Select();
webBrowserMain.Focus();
int numOfTries = 0;
repeat:
if (numOfTries < 10)
{
try
{
webBrowserMain.Document.Window.ScrollTo(0, 0);
webBrowserMain.Document.GetElementById("source").Focus();
//webBrowserMain.Document.GetElementById("source").InvokeMember("click");
}
catch
{//if the document hasn't loaded yet
numOfTries++;
System.Threading.Thread.Sleep(40);
goto repeat;
}
}
}
}
public static void openTranslateWindow()
{
formMain.Show();
formMain.TopMost = true;
formMain.WindowState = FormWindowState.Minimized;
formMain.Show();
formMain.WindowState = FormWindowState.Normal;
formMain.BringToFront();
formMain.webBrowserMain.Focus();
formMain.panelMain.Enabled = false;
formMain.Focus();
formMain.panelMain.Enabled = true;
formMain.Activate();
formMain.webBrowserMain.Select();
formMain.webBrowserMain.Focus();
}

尝试在显示主窗体时设置文本框焦点,而不是在文档完成时设置。
private void FormMain_Shown(object sender, EventArgs e)
{
BringToFront();
HtmlElement textArea = webBrowserMain.Document.GetElementById("source");
if (textArea != null)
{
textArea.Focus();
}
}
