Introduction

Because the main job of a brush is to fill a closed shape, the Graphics class provides a method that corresponds to each of the closed shapes we reviewed to draw in the previous lesson in order to fill it. The methods are:

• FillRectangle: Used to fill the interior of a rectangle or a square
• FillRectangle: Used to fill the interior of a series of rectangles
• FillEllipse: Used to fill the interior of an ellipse or a circle
• FillPolygon: Used to fill the interior of a polygon
• FillClosedCurve: Used to fill the interior of a closed curve
• FillPie: Used to fill the interior of a pie
• FillPath: Used to fill the interior of a graphic path

To fill out a shape, call one of these methods, pass it a brush value, followed by the location and dimensions of the shape. For example, if you want to draw a rectangle and fill it with a brush, you would use code similar to:

Imports System.Drawing
Imports System.Windows.Forms

Module Exercise

    Public Class Starter
        Inherits Form

        Dim components As System.ComponentModel.Container

        Public Sub New()
            InitializeComponent()
        End Sub

        Public Sub InitializeComponent()

        End Sub

        Private Sub FormPaint(ByVal sender As Object, _
                              ByVal e As PaintEventArgs) _
                              Handles MyBase.Paint

            e.Graphics.FillRectangle(SomeBrush, 20, 20, 200, 160)

        End Sub
    End Class

    Function Main() As Integer

        Dim frmStart As Starter = New Starter

        Application.Run(frmStart)

        Return 0
    End Function

End Module

Over all, there are four types of brushes.
