構文

Visual Basic (宣言)

Public ReadOnly Property
 Right As Integer

Visual Basic (使用法)

Dim instance As Control
Dim value As Integer

value = instance.Right

C#

public int Right { get;
 }

C++

public:
property int Right {
    int get ();
}

J#

/** @property */
public int get_Right ()

JScript

public function get Right

プロパティ値
Int32 はコントロールの右端とコンテナのクライアント領域の左端の間の距離をピクセルで示します。

解説

Right プロパティの値は、Left プロパティ値と Width プロパティ値の合計に等しくなります。

Right プロパティは読み取り専用です。Left プロパティまたは Width プロパティの値を変更するか、あるいは SetBounds、SetBoundsCore、UpdateBounds、または SetClientSizeCore の各メソッドを呼び出すことによって、このプロパティ値を間接的に変更できます。

使用例

フォームに 3 つの Button コントロールを作成し、サイズ関連と位置関連の各種プロパティを使用してそのサイズと位置を設定するコード例を次に示します。この例では、幅と高さが 300 ピクセル以上ある Form が存在している必要があります。

Visual Basic

' Create three buttons and place them on a form using 
' several size and location related properties. 
Private Sub AddOKCancelButtons()
   ' Set the button size and location using 
      ' the Size and Location properties. 
   Dim buttonOK As New Button()
   buttonOK.Location = New Point(136, 248)
   buttonOK.Size = New Size(75, 25)
   ' Set the Text property and make the 
   ' button the form's default button. 
   buttonOK.Text = "&OK"
   Me.AcceptButton = buttonOK
   
   ' Set the button size and location using the Top, 
   ' Left, Width, and Height properties. 
   Dim buttonCancel As New
 Button()
   buttonCancel.Top = buttonOK.Top
   buttonCancel.Left = buttonOK.Right + 5
   buttonCancel.Width = buttonOK.Width
   buttonCancel.Height = buttonOK.Height
   ' Set the Text property and make the 
   ' button the form's cancel button. 
   buttonCancel.Text = "&Cancel"
   Me.CancelButton = buttonCancel
   
   ' Set the button size and location using 
   ' the Bounds property. 
   Dim buttonHelp As New
 Button()
   buttonHelp.Bounds = New Rectangle(10, 10, 75, 25)
   ' Set the Text property of the button.
   buttonHelp.Text = "&Help"
   
   ' Add the buttons to the form.

 buttonCancel, buttonHelp})
