TabControl.GetTabRect メソッド
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)

Dim instance As TabControl Dim index As Integer Dim returnValue As Rectangle returnValue = instance.GetTabRect(index)
戻り値
指定したタブの境界を表す Rectangle。


1 つの TabPage がある TabControl を作成するコード例を次に示します。この例では、GetTabRect メソッドを使用して、tabPage1 タブ領域を表す Rectangle を取得しています。myTabRectRectangle は、DrawItem イベントによって描画されます。
この例では、System.Drawing 名前空間と System.Windows.Forms 名前空間を使用します。
