範例

注意

Microsoft 記事本僅做為文字提供者。 Microsoft 記事本不保證支援所要求的屬性值。

private void GetIsItalicAttribute()
{
    // Start application.
    Process p = Process.Start("Notepad.exe", "text.txt");

    // target --> The root AutomationElement.
    AutomationElement target = AutomationElement.FromHandle(p.MainWindowHandle);

    // Specify the control type we're looking for, in this case 'Document'
    PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document);

    AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);

    TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;

    if (textpatternPattern == null)
    {
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
        return;
    }

    Object oAttribute = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.IsItalicAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixture of italic and non-italic.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}

Private Sub GetIsItalicAttribute()
    ' Start application.
    Dim p As Process = Process.Start("Notepad.exe", "text.txt")

    ' target --> The root AutomationElement.
    Dim target As AutomationElement = AutomationElement.FromHandle(p.MainWindowHandle)

    ' Specify the control type we're looking for, in this case 'Document'
    Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)

    Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)

    Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)

    If (textpatternPattern Is Nothing) Then
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
        Return
    End If

    Dim oAttribute As Object = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.IsItalicAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixture of italic and non-italic.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If
End Sub

備註

消費者介面自動化用戶端應用程式會使用此識別碼。 消費者介面自動化提供者應該使用 中的 TextPatternIdentifiers 對等欄位。

消費者介面自動化用戶端藉由呼叫 GetAttributeValue 來取得 屬性的值。

這個屬性的值的類型為 Boolean 。 預設值是 false。
