Exemples

L’exemple de code suivant dessine le curseur spécifié sur le formulaire dans sa taille normale et en mode étiré, deux fois sa taille.The following code example draws the specified cursor on the form in its normal size, and in stretched mode, twice its size. Cet exemple nécessite que vous disposiez d’un Form Cursor objet et d’un objet à passer à la méthode quand elle est appelée.This example requires that you have a Form and a Cursor object to pass into the method when it is called.

void DrawCursorsOnForm( System::Windows::Forms::Cursor^ cursor )

   // If the form's cursor is not the Hand cursor and the
   // Current cursor is the Default, Draw the specified
   // cursor on the form in normal size and twice normal size.
   if ( this->Cursor != Cursors::Hand && System::Windows::Forms::Cursor::Current == Cursors::Default )
   {
      
      // Draw the cursor stretched.

      Rectangle rectangle = Rectangle(Point(10,10),System::Drawing::Size( cursor->Size.Width * 2, cursor->Size.Height * 2 ));

      rectangle.Location = Point(rectangle.Width + rectangle.Location.X,rectangle.Height + rectangle.Location.Y);
      rectangle.Size = cursor->Size;
      cursor->Draw( graphics, rectangle );

Remarques

La commande de dessin provient de la surface graphique représentée par le g paramètre, mais un Graphics objet ne contient pas d’informations sur le rendu d’une image donnée, donc elle passe l’appel à l' Cursor objet.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. La DrawStretched méthode étire l’image pour remplir le spécifié Rectangle lorsque le curseur est dessiné.The DrawStretched method stretches the image to fill the specified Rectangle when the cursor is drawn.
