TextPatternRange.GetBoundingRectangles メソッド

定義

名前空間:

System.Windows.Automation.Text

アセンブリ:

UIAutomationClient.dll

テキスト範囲内のテキストの表示されている各行 (全体または一部) に外接する四角形のコレクションを取得します。

public:
 cli::array <System::Windows::Rect> ^ GetBoundingRectangles();

public System.Windows.Rect[] GetBoundingRectangles ();

member this.GetBoundingRectangles : unit -> System.Windows.Rect[]

Public Function GetBoundingRectangles () As Rect()

戻り値

Rect[]

テキスト範囲内の各行 (全体または一部) に外接する四角形の配列。

低次元テキスト範囲の空の配列。

完全に画面外となる、スクロール アウトする、または重なったウィンドウによって隠れる画面座標を持つテキスト範囲を表す空の配列。

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
