Ett textområde som matchar den angivna texten. annars null (Nothing i Visual Basic).

Exempel

 private TextPatternRange TextFromSelection(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 null;
    }
    TextPatternRange[] tprSelection = textpatternPattern.GetSelection();
    // Find 'text' in selection range
    return tprSelection[0].FindText("text", false, true);
}

Private Function TextFromSelection(ByVal target As AutomationElement) As TextPatternRange
    ' 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 Nothing
    End If
    Dim currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
    ' Find 'text' in selection range
    Return currentSelection(0).FindText("text", False, True)

Kommentarer

Det finns ingen differentiering mellan dold och synlig text. UI Automation klienter kan använda IsHiddenAttribute för att kontrollera textens synlighet.
