TextPatternRange.MoveEndpointByRange Yöntem

Tanım

Metin aralığının bir uç noktasını ikinci bir metin aralığının belirtilen uç noktasına taşır.

public:
 void MoveEndpointByRange(System::Windows::Automation::Text::TextPatternRangeEndpoint endpoint, System::Windows::Automation::Text::TextPatternRange ^ targetRange, System::Windows::Automation::Text::TextPatternRangeEndpoint targetEndpoint);
public void MoveEndpointByRange (System.Windows.Automation.Text.TextPatternRangeEndpoint endpoint, System.Windows.Automation.Text.TextPatternRange targetRange, System.Windows.Automation.Text.TextPatternRangeEndpoint targetEndpoint);
member this.MoveEndpointByRange : System.Windows.Automation.Text.TextPatternRangeEndpoint * System.Windows.Automation.Text.TextPatternRange * System.Windows.Automation.Text.TextPatternRangeEndpoint -> unit
Public Sub MoveEndpointByRange (endpoint As TextPatternRangeEndpoint, targetRange As TextPatternRange, targetEndpoint As TextPatternRangeEndpoint)

Parametreler

endpoint
TextPatternRangeEndpoint

Taşınacak uç nokta.

targetRange
TextPatternRange

Aynı metin sağlayıcısından başka bir aralık.

targetEndpoint
TextPatternRangeEndpoint

Diğer aralıktaki bir uç nokta.

Örnekler

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

    // target --> The root AutomationElement.
    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;
    }
    TextPatternRange[] currentSelection = textpatternPattern.GetSelection();
    TextPatternRange[] currentVisibleRanges = textpatternPattern.GetVisibleRanges();

    currentSelection[0].MoveEndpointByRange(
        TextPatternRangeEndpoint.Start,
        currentVisibleRanges[0], 
        TextPatternRangeEndpoint.Start);
}

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

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

    Dim currentVisibleRanges As TextPatternRange() = textpatternPattern.GetVisibleRanges()
    currentSelection(0).MoveEndpointByRange(TextPatternRangeEndpoint.Start, _
                                     currentVisibleRanges(0), _
                                     TextPatternRangeEndpoint.Start)

Açıklamalar

Taşınan uç nokta aynı metin aralığının diğer uç noktasını geçerse, diğer uç nokta da taşınır ve bu da bozuk bir aralıkla sonuçlanır ve uç noktaların doğru sıralanmasını sağlar (yani, Start her zaman küçük veya eşittir End).

Şunlara uygulanır
