Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following action:

• Creates a solid blue brush.

• Creates an array of three rectangles.

• Fills the three rectangular areas on the screen.

public:
   void FillRectanglesRectangleF( PaintEventArgs^ e )
   {
      // Create solid brush.
      SolidBrush^ blueBrush = gcnew SolidBrush( Color::Blue );

      // Create array of rectangles.
      array<RectangleF>^ rects = {RectangleF(0.0F,0.0F,100.0F,200.0F),RectangleF(100.0F,200.0F,250.0F,50.0F),RectangleF(300.0F,0.0F,50.0F,100.0F)};

      // Fill rectangles to screen.
      e->Graphics->FillRectangles( blueBrush, rects );
   }

private void FillRectanglesRectangleF(PaintEventArgs e)
{

    // Create solid brush.
    SolidBrush blueBrush = new SolidBrush(Color.Blue);

    // Create array of rectangles.
    RectangleF[] rects = { new RectangleF(0.0F, 0.0F, 100.0F, 200.0F), new RectangleF(100.0F, 200.0F, 250.0F, 50.0F), new RectangleF(300.0F, 0.0F, 50.0F, 100.0F) };

    // Fill rectangles to screen.
    e.Graphics.FillRectangles(blueBrush, rects);
}

Private Sub FillRectanglesRectangleF(ByVal e As PaintEventArgs)

    ' Create solid brush.
    Dim blueBrush As New SolidBrush(Color.Blue)

    ' Create array of rectangles.
    Dim rects As RectangleF() = {New RectangleF(0.0F, 0.0F, 100.0F, 200.0F), _
    New RectangleF(100.0F, 200.0F, 250.0F, 50.0F), _
    New RectangleF(300.0F, 0.0F, 50.0F, 100.0F)}

    ' Fill rectangles to screen.
