JFrame help

LiquidDragon · **Posted:** Wed Jul 07, 2004 9:03 am

I am very new to java and it is very confusing. I started first with turing and now im onto java so i took this course. One of our labs was to create a program to maximize the size of the frame and put it at the top of the screen.

Here is what i have so far.

code:

/**
* A JFrame that can double in width.
*/

import javax.swing.*;
import java.awt.*;

public class MaxWindow extends JFrame {

Dimension d= Toolkit.getDefaultToolkit().getScreenSize();
int screenWidth= (int) d.getWidth();
int screenHeight= (int) d.getHeight();

public MaxWindow(String t) {
super (t);
}

public MaxWindow() {
// this automatically calls super().
}

public void maxWidth() {
setSize (screenWidth, getHeight());
}

public void maxHeight() {

}
}

NOTE: I am using DrJava to write and test all this. Any help would be great.

ur trying to make a fullscreen window right?.. heh ask Dan, i know he did it for his FP.

i do not think that is what he whonts, b/c he side maximised like the window mode. but i will post the fullscreen code just the same:

class from my FP that dose fullscreen:

code:

import java.awt.*;
import javax.swing.*;

/**
*a fullscreen frame to be used for the game
*@author Dan
*/
public class QFTBFrame extends JFrame
{
private GraphicsEnvironment env;
private GraphicsDevice device;
private boolean isFullScreen;

/**
   *a new frame that will be fullscreen if the system suports it
   */
public QFTBFrame()
{
super();

env = GraphicsEnvironment.getLocalGraphicsEnvironment();
device = env.getDefaultScreenDevice();

isFullScreen = device.isFullScreenSupported();

if(isFullScreen)
{
setUndecorated(true);
setResizable(false);
device.setFullScreenWindow(this);
}
else
{
setUndecorated(false);
setResizable(true);
System.out.println("Error: your system dose not sport fullscreen, trying normal size...");
}
}

/**
   *should take the system out of fullscreen mode (untested)
   */
public void end()
{
if(isFullScreen)
{
device.setFullScreenWindow(null);
}
}
}

fullscreen is a bit bugy esepltay when using it with GUIs like awt and swing and it dose not work on all systems.

It's not the fullscreen i want. I need to write a class that has a method that can maximize the width and another method to maximize the height. We are learning all this in a class im taking but i find java very confusing.
