Exemples

L’exemple de code suivant dessine le curseur spécifié sur le formulaire dans sa taille normale, et en mode étendu, deux fois sa taille. Cet exemple nécessite que vous disposiez d’un Form objet et d’un Cursor objet à passer à la méthode lorsqu’elle est appelée.

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.
      Graphics^ graphics = this->CreateGraphics();
      Rectangle rectangle = Rectangle(Point(10,10),System::Drawing::Size( cursor->Size.Width * 2, cursor->Size.Height * 2 ));
      cursor->DrawStretched( graphics, rectangle );
      
      // Draw the cursor in normal size.
      rectangle.Location = Point(rectangle.Width + rectangle.Location.X,rectangle.Height + rectangle.Location.Y);
      rectangle.Size = cursor->Size;
      cursor->Draw( graphics, rectangle );
      
      // Dispose of the cursor.
      delete cursor;
   }
}

private void DrawCursorsOnForm(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 & 
     Cursor.Current == Cursors.Default)
   {
      // Draw the cursor stretched.
      Graphics graphics = this.CreateGraphics();
      Rectangle rectangle = new Rectangle(
        new Point(10,10), new Size(cursor.Size.Width * 2, 
        cursor.Size.Height * 2));
      cursor.DrawStretched(graphics, rectangle);
        
      // Draw the cursor in normal size.
      rectangle.Location = new Point(
      rectangle.Width + rectangle.Location.X, 
        rectangle.Height + rectangle.Location.Y);
      rectangle.Size = cursor.Size;
      cursor.Draw(graphics, rectangle);

      // Dispose of the cursor.
      cursor.Dispose();
   }
}

Private Sub DrawCursorsOnForm(cursor As 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 (Not Me.Cursor.Equals(Cursors.Hand)) And _
     Cursor.Current.Equals(Cursors.Default) Then

      ' Draw the cursor stretched.
      Dim graphics As Graphics = Me.CreateGraphics()
      Dim rectangle As New Rectangle(New Point(10, 10), _
        New Size(cursor.Size.Width * 2, cursor.Size.Height * 2))
      cursor.DrawStretched(graphics, rectangle)
     
      ' Draw the cursor in normal size.
      rectangle.Location = New Point(rectangle.Width + _
        rectangle.Location.X, rectangle.Height + rectangle.Location.Y)
      rectangle.Size = cursor.Size
      cursor.Draw(graphics, rectangle)

      ' Dispose of the cursor.
      cursor.Dispose()
   End If

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. Il transmet donc l’appel à l’objet Cursor . La DrawStretched méthode étire l’image pour remplir le spécifié Rectangle lorsque le curseur est dessiné.
