FlowLayoutPanel-Klasse

Stellt einen Bereich dar, in dem der Inhalt dynamisch horizontal oder vertikal angeordnet wird.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

Nicht zutreffend.

Das FlowLayoutPanel-Steuerelement ordnet seinen Inhalt in horizontaler oder vertikaler Flussrichtung an. Der Inhalt kann zeilenweise oder spaltenweise umbrochen werden. Wenn der Inhalt nicht umbrochen wird, kann er auch abgeschnitten werden.

Sie können die Flussrichtung angeben, indem Sie den Wert der FlowDirection-Eigenschaft festlegen. Die Flussrichtung des FlowLayoutPanel-Steuerelements wird in Layouts mit Leserichtung von rechts nach links (RNL) ordnungsgemäß umgekehrt. Ob der Inhalt des FlowLayoutPanel-Steuerelements umbrochen oder abgeschnitten wird, können Sie auch angeben, indem Sie den Wert der WrapContents-Eigenschaft festlegen.

Jedes Windows Forms-Steuerelement, einschließlich anderer Instanzen von FlowLayoutPanel, kann ein untergeordnetes Element des FlowLayoutPanel-Steuerelements sein. Mit dieser Funktion können Sie komplizierte Layouts erstellen, die sich zur Laufzeit an die Dimensionen des Formulars anpassen.

Das Andock- und Verankerungsverhalten untergeordneter Steuerelemente unterscheidet vom Verhalten in anderen Containersteuerelementen. Sowohl das Andocken als auch das Verankern erfolgen relativ zum größten Steuerelement in der Flussrichtung. Weitere Informationen finden Sie unter Gewusst wie: Verankern und Andocken von untergeordneten Steuerelementen in einem FlowLayoutPanel-Steuerelement.

Im folgenden Beispiel wird das Festlegen der FlowDirection-Eigenschaft und der WrapContents-Eigenschaft für ein FlowLayoutPanel-Steuerelement veranschaulicht.
