使用例

[Visual Basic, C#, C++] 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例を次に示します。この例は、幅と高さが 300 ピクセル以上ある Form があることを前提にしています。

 
' 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.
   Me.Controls.AddRange(New Control() {buttonOK, buttonCancel, buttonHelp})
End Sub
