public class LwLink

extends LwStButton

implements Cursorable

This component is like text links that are used in "html". The link component uses one of the three colors to show its state. Use setColor method to set the color for the specified link state.

The class performs action event when the link has been pressed. Use the addActionListener and removeActionListener methods to catch the event.

Constructor Detail

LwLink

public LwLink(java.lang.String s)

Constructs a link component with the specified link text.

Parameters:

s - the specified link text.

setColor

public void setColor(int state,
                     java.awt.Color c)

Sets the specified link text color for the given state.

Parameters:

state - the specified state. Use one of the following values:

• LwStButton.ST_ONSURFACE
• LwStButton.ST_PRESSED
• LwStButton.ST_OUTSURFACE

c - the specified color.

getCursorType

public int getCursorType(LwComponent target,
                         int x,
                         int y)

Gets the cursor type. The method is an implementation of Cursorable interface and it is used to define cursor type. The component returns java.awt.Cursor.HAND_CURSOR cursor type.

Specified by:

getCursorType in interface Cursorable

Parameters:

target - the specified component.

x - the specified x coordinate of the mouse cursor relatively the component.

y - the specified y coordinate of the mouse cursor relatively the component.

Returns:

a cursor type.

stateChanged

protected void stateChanged(int s,
                            int ps)

Invoked when the state of the component has been changed. The method is used to listen state changing and setting appropriate link text color for the state.

Overrides:

stateChanged in class LwStButton

Parameters:

s - the new state of the component.

ps - the previous state of the component.
