public class LGStyle
extends javax.swing.JPanel
implements java.awt.event.ItemListener, javax.swing.event.ChangeListener

LGStyle is a widget presenting a choice of drawing style. It is composed of various widgets.

• a preview zone at the front showing what the drawing style looks like
• a drop down menu to choose colour
• a drop down menu to choose the line style
• a widget to choose the line width
• a drop down menu to the symbol style
• a widget to choose the symbol size

This object then got various method to interact with this infomration
