Class PlaygroundComponent

          javax.swing.JComponent
              cz.nipax.hippo.pexeso.PlaygroundComponent

All Implemented Interfaces:

java.awt.event.MouseListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener

public class PlaygroundComponent
extends javax.swing.JComponent
implements java.awt.event.MouseListener

PlaygroundComponent creates playground and gets user input. It requires to have valid Playground in constructor to know what to display. Playground should call repaint if gamestate changes.

If any AI wants to receive input from user, it needs to register. Just call registerAI(cz.nipax.hippo.pexeso.AI). Note that PlaygroundComponent stores only one AI. So if game is with more AIs that want user input, registerAI(cz.nipax.hippo.pexeso.AI) everytime AI on turn is changed. This call is done by Playground.switchplayer(boolean), so AI class doesn't have to do it.

Currently active AI. Needed to know where to pass user input. May be null.

m_theme

PGTheme m_theme

All graphic and dimensions of graphics

Constructor Detail

PlaygroundComponent

PlaygroundComponent(Playground pg)

Perpares whole class for use. Loads images of pexesos :-) Also register self into Playground via Playground.setPGC(cz.nipax.hippo.pexeso.PlaygroundComponent).

Parameters:

pg - what playground to display

Method Detail

println

public void println(java.lang.String s)

Inteligent message printing. It is possible to disable all messages in one place - for some kind of final release

registerAI

public void registerAI(AI ai)

Set current AI. Changes m_ai.

Parameters:

ai - the current ai.

setTheme

public void setTheme(PGTheme theme)

Chenges current theme. Owerwrites m_theme.

Parameters:

theme - new theme

createback

public void createback()

getPreferredSize

public java.awt.Dimension getPreferredSize()

Set default size of playground.

Overrides:

getPreferredSize in class javax.swing.JComponent

paintComponent

public void paintComponent(java.awt.Graphics g)

Overrides:

paintComponent in class javax.swing.JComponent

paint_offscreen

public void paint_offscreen(boolean updateonly,
                            java.awt.Graphics gr)

Paints playground and game statistic. Performs full redraw but without clearing backgorund. Uses cliping for better perfomance.

repaint_later

public void repaint_later(boolean update_only)

This should be caled from Playground if repaint is wanted.

Parameters:

update_only - if only few cards chenged visibility - for incremental painting and thus better performance. This is critical for Kaffe if you want to be able to play th egame.

drawImage_true

private void drawImage_true(java.awt.Graphics g,
                            java.awt.Image img,
                            int x,
                            int y)

Graphics.drawImage may return false and then no image is drawn. Usually repeted paint with some delay correct this. The problem was observed with sun java 1.5. classpath worked with no problem. It looks like the picture need some time to get ready before drawing. It happens for one picture only once.
