TabControl.GetTabRect(Int32) メソッド


タブ コントロール内の指定したタブの外接する四角形を返します。Returns the bounding rectangle for a specified tab in this tab control.

 System::Drawing::Rectangle GetTabRect(int index);
public System.Drawing.Rectangle GetTabRect (int index);
member this.GetTabRect : int -> System.Drawing.Rectangle
Public Function GetTabRect (index As Integer) As Rectangle



指定したタブの 0 から始まるインデックス。The zero-based index of the tab you want.


指定したタブの境界を表す RectangleA Rectangle that represents the bounds of the specified tab.


インデックスが 0 未満です。The index is less than zero.

- または --or- インデックスが、Count 以上です。The index is greater than or equal to Count.

次のコード例ではTabControl 、をTabPage使用してを作成します。The following code example creates a TabControl with one TabPage. この例ではGetTabRect 、メソッドを使用Rectangleして、 tabPage1タブ領域を表すを取得します。This example uses the GetTabRect method to get a Rectangle that represents the tabPage1 tab area. myTabRectDrawItemイベントによって描画されます。 RectangleThe myTabRect Rectangle is drawn by the DrawItem event.

この例System.DrawingSystem.Windows.Formsは、名前空間と名前空間を使用します。Use the System.Drawing and System.Windows.Forms namespaces with this example.
