Exempel

• I följande kodexempel läggs en skugga till i en ListBox med hjälp av en SolidBrush.

Det här exemplet är utformat för att användas med ett Windows-formulär. Om du vill köra det här exemplet klistrar du in den här koden i ett formulär och anropar AddShadow metoden när du hanterar formulärets Paint händelse. Kontrollera att formuläret innehåller ett ListBox med namnet listBox1.

      // Add them together and save the result in shadowSize.
      shadowSize = shadowSize + addSize;

      // Get the location of the ListBox and convert it to a PointF.
      PointF shadowLocation = listBox1->Location;
