Boolean

Valeur Boolean qui spécifie si la première figure du tracé ajouté appartient à la dernière figure de ce tracé.A Boolean value that specifies whether the first figure in the added path is part of the last figure in this path. La valeur true spécifie que la première figure du tracé ajouté fait partie de la dernière figure de ce tracé, le cas échéant.A value of true specifies that (if possible) the first figure in the added path is part of the last figure in this path. La valeur false spécifie que la première figure du tracé ajouté n'appartient pas à la dernière figure de ce dernier.A value of false specifies that the first figure in the added path is separate from the last figure in this path.

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 deux tracés, un triangle vers le haut et l’autre un triangle vers le haut.Creates two paths one a right-side-up triangle and the other an up-side-down triangle.

  • Ajoute le deuxième chemin d’accès au premier.Adds the second path to the first.

  • Dessine le chemin d’accès résultant à l’écran.Draws the resultant path to the screen.
