Exemples

L’exemple de code suivant est conçu pour être utilisé avec Windows Forms, et il requiert PaintEventArgs e un OnPaint objet d’événement.The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, an OnPaint event object. Le code effectue les actions suivantes :The code performs the following actions:

  • Crée un LinearGradientBrush.Creates a new LinearGradientBrush.

  • Dessine une ellipse à l’écran à l’aide de ce pinceau.Draws an ellipse to the screen using this brush.

  • Clone le LinearGradientBrush ( clonedLGBrush ).Clones the LinearGradientBrush (clonedLGBrush).

  • Dessine une ellipse à l’écran, directement sous la première ellipse, à l’aide du pinceau cloné.Draws an ellipse to the screen directly below the first ellipse, using the cloned brush.
