Constructor Detail

CarGameGUI

public CarGameGUI(java.lang.String title,
                  CarGameController r)

Creates a window for displaying the car game.

Parameters:

title - Name to be printed in the window's titlebar.

Method Detail

close

public void close()

Closes the window and allows the main program to exit cleanly. If a program ends without calling this method, the image window, although able to hide, will remain in memory indefinitely.

paintComponent

public void paintComponent(java.awt.Graphics g)

Paints the window contents using the provided Graphics object.

Overrides:

paintComponent in class javax.swing.JComponent

update

public void update(java.awt.Graphics g)

The actual painting code is here instead of paintComponent().

Overrides:

update in class javax.swing.JComponent

showMe

public void showMe()

Displays the window. This starts the thread which repaints the window's contents, too.

getShowCars

public boolean getShowCars()

Indicates whether the GUI is displaying cars.

Returns:

whether the GUI is displaying cars.

setShowCars

public void setShowCars(boolean show)

To save running time, we may choose not to display cars.

Parameters:

show - Whether to show cars.

setLocation

public void setLocation(int x,
                        int y)

Places the window. The upper left coordinate of the window will be placed at position (x,y) with respect to the upper left corner of the screen.

Overrides:

setLocation in class java.awt.Component

setOffset

public void setOffset(int x)

Specifies the distance on the highway that corresponds to the left end of the window.

Parameters:

x -

getGameController

public CarGameController getGameController()

Returns a reference to the CarGameController that controls the game which this GUI is displaying.

Returns:

a reference to the CarGameController that controls the game which this GUI is displaying.
