Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie die SizingGripMember , StatusBarPanel.Alignment, StatusBarPanel.AutoSizeStatusBarPanel.Width, und StatusBarPanel.BorderStyle verwendet und wie das PanelClick Ereignis behandelt wird.

Fügen Sie zum Ausführen des Beispiels den folgenden Code in ein Formular ein. Rufen Sie die InitializeStatusBarPanels -Methode im Konstruktor oder Load Ereignishandler des Formulars auf.

Hinweise

Sie können diese Eigenschaft verwenden, um einen Größengriff anzuzeigen, um dem Benutzer einen Hinweis zu geben, wann die Größe eines Formulars geändert werden kann. Wenn die FormBorderStyle -Eigenschaft von Form auf eine Rahmenart festgelegt ist, die nicht in der Größe geändert werden kann, z Fixed3D . B. oder FixedDialog, sollten Sie die SizingGrip -Eigenschaft auf false festlegen, um den Benutzer daran zu hindern, die Größe des Formulars zu ändern.
