ToolBarButton.PartialPush-Eigenschaft

Ruft einen Wert ab, der angibt, ob eine An-Aus-Schaltfläche einer Symbolleiste teilweise gedrückt ist, oder legt diesen fest.

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

Syntax

'Declaration
Public Property PartialPush As Boolean
'Usage
Dim instance As ToolBarButton
Dim value As Boolean

value = instance.PartialPush

instance.PartialPush = value

public bool PartialPush { get; set; }

public:
property bool PartialPush {
    bool get ();
    void set (bool value);
}

/** @property */
public boolean get_PartialPush ()

/** @property */
public void set_PartialPush (boolean value)

public function get PartialPush () : boolean

public function set PartialPush (value : boolean)

Eigenschaftenwert

true, wenn eine umschaltbare Symbolleisten-Schaltfläche teilweise gedrückt ist, andernfalls false. Der Standardwert ist false.

Hinweise

Wenn PartialPush auf true festgelegt ist, wird die Oberfläche der Symbolleisten-Schaltfläche grau dargestellt. Diese Darstellung unterscheidet sich von der abgeblendeten Darstellung, wenn die Enabled-Eigenschaft auf false festgelegt ist, da bei der teilweise gedrückten Darstellung die gesamte Oberfläche der Schaltfläche verschwommen angezeigt wird. Diese Eigenschaft hat nur dann Auswirkungen, wenn ToolBarButtonStyle auf ToggleButton festgelegt ist.

Beispiel

Im folgenden Codebeispiel wird die Verwendung der Pushed-Eigenschaft und der PartialPush-Eigenschaft veranschaulicht. Zum Ausführen des Beispiels fügen Sie folgenden Code in ein Formular ein, das eine RichTextBox mit dem Namen RichTextBox1 enthält. Rufen Sie die InitializeToolBar-Methode im Konstruktor oder in der Load-Methode des Formulars auf.
