SystemInformation.MouseHoverTime-Eigenschaft

Hinweis: Diese Eigenschaft ist neu in .NET Framework, Version 2.0.

Ruft die Zeitspanne in Millisekunden ab, die sich der Mauszeiger im Hoverrechteck befinden muss, bevor eine Maushovermeldung generiert wird.

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

public static int MouseHoverTime { get; }
/** @property */
public static int get_MouseHoverTime ()

public static function get MouseHoverTime () : int

Eigenschaftenwert

Die Zeitspanne in Millisekunden, die sich der Mauszeiger im Hoverrechteck befinden muss, bevor eine Maushovermeldung generiert wird.

Die MouseHoverTime-Eigenschaft gibt die Zeitspanne in Millisekunden an, die sich ein Mauszeiger in einem Bereich von der Größe der MouseHoverSize-Eigenschaft befinden muss, damit eine Maushovermeldung generiert wird.

Die MouseHoverSize-Eigenschaft gibt die Größe des Rechtecks in Pixel an, in dem sich der Mauszeiger für die Dauer der Maushover-Zeitspanne befinden muss, bevor eine Maushovermeldung generiert wird.

Im folgenden Codebeispiel werden alle Eigenschaften der SystemInformation-Klasse in einer ListBox aufgelistet. Wenn ein Listenelement ausgewählt wird, wird der aktuelle Wert der Eigenschaft in einer TextBox angezeigt.
