範例

下列範例示範如何取得Microsoft記事本中文字範圍的屬性值。

注意

private void GetFontWeightAttribute()
{
    // 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.FontWeightAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixed font weights.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}
Private Sub GetFontWeightAttribute()
    ' 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.FontWeightAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixed font weights.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If
End Sub

備註

此屬性是指字型的相對筆劃、粗細或粗細。

此屬性會在 GDI LOGFONT 中的 欄位之後 lfWeight 建立模型。 為了一致性,LOGFONT 採用下列值:0=DontCare、100=Thin、200=ExtraLight 或 UltraLight、300=Light、400=Normal 或 Regular、500=Medium、600=SemiBold 或 DemiBold、700=Bold、800=ExtraBold 或 UltraBold,以及 900=Heavy 或 Black。

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 取得 屬性的值。

此屬性的值的類型為 Int32 。 預設值是 zero
