定義

名前空間:

System.Windows.Automation.Text

アセンブリ:

UIAutomationClient.dll

テキスト範囲の 1 つのエンドポイントを、2 番目のテキスト範囲の指定のエンドポイントに移動します。

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)

パラメーター

endpoint

TextPatternRangeEndpoint

移動するエンドポイント。

targetRange

TextPatternRange

同じテキスト プロバイダーからの別の範囲。

targetEndpoint

TextPatternRangeEndpoint

他の範囲にあるエンドポイント。

例

 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);
}

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

    ' target --> The root AutomationElement.
    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 currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
    Dim currentVisibleRanges As TextPatternRange() = textpatternPattern.GetVisibleRanges()
    currentSelection(0).MoveEndpointByRange(TextPatternRangeEndpoint.Start, _
                                     currentVisibleRanges(0), _
                                     TextPatternRangeEndpoint.Start)
End Sub

注釈

移動中のエンドポイントが同じテキスト範囲の他のエンドポイントと交差する場合、その他のエンドポイントも移動され、結果として生成される範囲が縮退し、エンドポイントの正しい順序が保証されます (つまり、 Start 常に 以下 Endです)。
