定義

名前空間:
System.Windows.Automation.Text
アセンブリ:

public:

member this.GetBoundingRectangles : unit -> System.Windows.Rect[]
Public Function GetBoundingRectangles () As Rect()

Rect[]

テキスト範囲内のテキストの全行または一部行の外接する四角形の配列。

縮退したテキスト範囲の空の配列。

画面座標を含むテキスト範囲の空の配列。完全に画面外に配置されたり、ビューからスクロールされたり、ウィンドウが重なって隠れたりします。

例

 private Rect[] BoundingRectanglesFromSelection(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[] currentSelection = textpatternPattern.GetSelection();

    return currentSelection[0].GetBoundingRectangles();
}

Private Function BoundingRectanglesFromSelection(ByVal target As AutomationElement) As Rect()
    ' 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()
    Return currentSelection(0).GetBoundingRectangles()
End Function
