Parameter

g
Graphics Graphics Graphics Graphics

Beispiele

Im folgenden Codebeispiel wird der angegebene Cursor auf dem Formular in der normalen Größe und im gestreckten Modus zweimal in der Größe gezeichnet.The following code example draws the specified cursor on the form in its normal size, and in stretched mode, twice its size. Für dieses Beispiel ist es erforderlich, Form dass Sie Cursor über ein-und ein-Objekt verfügen, das beim Aufrufen an die-Methode übergeben wird.This example requires that you have a Form and a Cursor object to pass into the method when it is called.

Hinweise

Der Zeichnungs Befehl stammt aus der Grafik Oberfläche, die durch g den-Parameter dargestellt Graphics wird, aber ein-Objekt enthält keine Informationen zum Rendervorgang eines bestimmten Bilds, sodass der Cursor -Befehl an das-Objekt übergeben wird.The drawing command originates on the graphics surface represented by the g parameter, but a Graphics object does not contain information about how to render a given image, so it passes the call to the Cursor object. Die DrawStretched -Methode dehnt das Bild aus, um Rectangle die angegebene auszufüllen, wenn der Cursor gezeichnet wird.The DrawStretched method stretches the image to fill the specified Rectangle when the cursor is drawn.
