JFrame Won't Hide When New Applet Starts

May 18, 2014

I have a login window, which when sucessful will activate a new Applet/JFrame. The problem is that the login window remains in the background under the new JFrame. I want this to diappear. I want to either set the visibility to false, or close it.This is how the new window is started:

if(sucess.equals("flase")){

DBAccess dba = new DBAccess();
dba.setFname(fnameusr); //fnameusr
dba.setLname(lnameusr); //lnameusr
dba.main(null);

//LogIn.exit(0);
}else{
JOptionPane.showMessageDialog(null, "Your credentials were not entered correctly or you may not be authorised to access this system.");

Generic RPG Game - Java Applet When Adding Subroutine

Jul 11, 2014

I am trying to design a generic RPG game. The issue I am having right now is in my Class I have a subroutine (think that is the correct term) that is basically set up to hold a series of Print Statements. I am really just trying to get some Values that are stored within the Applet, have them assigned to their correct variables and then returned in the print statement. Yet, when I run the applet it just pops up the Applet blank and gives me a long list of errors and I really don't understand when they mean.

Here is the code:

The Class

public class CharacterSheet {
final String NL = System.getProperty("line.separator");
public String characterName;
int playerStr;
int playerCha;

[Code] ....

And the error messages:

Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException: String is null
at sun.java2d.SunGraphics2D.drawString(Unknown Source)
at TFApplet.paint(TFApplet.java:15)

Swing/AWT/SWT :: Adding ContentPane To JFrame

Apr 18, 2014

The program loads, but nothing shows. I did some research and saw that I needed to set the JFrame to visible at the bottom of the frame section. I made the change, but it still does not show anything. Do I need to add everything that I added to the content pane to the frame? From my understanding you add elements to the panel, the panel to the contentPane, then the pane to the frame...

/*
* Filename: UserInformation.java
*/
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;

Swing/AWT/SWT :: BorderLayout - Adding Multiple Video Game Oriented Objects Such As Sprites To JFrame?

May 24, 2014

I decided to write a small Java program to experiment around with BorderLayout, because I'm developing a Java game and I need to have 2 objects placed in a single JFrame at the same time, and everyone I asked said I need BorderLayout to do that.Before you answer: Also, is using BorderLayout the best option for adding multiple video game oriented objects such a sprites to a JFrame?

So the Java program I wrote is supposed to place a JButton on the JFrame and ALSO place a graphic component (a rectangle in this case). The problem is, only the button shows up, as can be seen in the image link below: URL....

Here is the code:

**main.java** --> The main method class + JFrame/JPanel/JButton constructor
import java.awt.BorderLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class main {

Passing A Value From Applet To JavaScript

Feb 5, 2014

I have a java application in which when starting it a map is opened and a screen is captured. The capturing is in certain time interval. I want to enable the user to change the interval for the automatic capturing the map. I placed a text box in a JPanel. I want to pass the value which was entered in it to the html page which opens a Google map. Since I am new in java programming, I found that I can do it by using applets. I made an applet, and tried to call it in the html file. But now instead of opening the map file in a browser, it opens very quickly only black window.

Here is my applet:

package cege.ui;
import java.applet.Applet;
import java.io.IOException;
import cege.ui.GuiMain;
public class AppletTInterval extends Applet {
private int TimeInterval=0;

[Code] .....

And the code in the html file where I try to call the applet, i.e. to pass the value which is returned by the applet is:

<script src=
<!--"https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = { id:'AppletTInterval',
code:'cege.ui.AppletTInterval', width:1, height:1} ;
var parameters = { jnlp_href: 'AppletTInterval.jnlp'} ;

[Code] .....

Can I use this way to pass a value from the java class file (from the JTextField into the html file?

Swing/AWT/SWT :: Simple Applet Won't Run

Mar 11, 2002

I coded up a simple applet and some html with an applet tag and it tested out OK using the applet viewer. But it doesn't do anything (except draw a grey empty box 100x200) when executed from the application server. For the applicaton server test, I put the applet tag in the HTML Body of the JSP page i.e.

<applet code=CatApplet.class height=100 width=200> </applet>

The applet class file is in the same directory as the JSP page. The source for it is:

import java.awt.*;import java.awt.event.*;import javax.swing.*;import java.io.*;import java.net.*;
import java.util.Date;public class CatApplet extends JApplet{public void init (){setBackground(Color.green);
resize (250,100);}public void paint (Graphics g){g.drawString ("lets get some cat gui going", 35, 15);}}

Why won't my applet run when the applet tags are in the JSP page?

Difference Between Application And Applet?

Apr 13, 2014

Can explain difference between applet and application?

What are differences in code? How to write application?

What are differences in use? I looked for some answers, but I can't understand what they are talking about.

For example:

Application:

Called as stand-alone application as application can be executed from command prompt

Applet:

Requires some third party tool like a browser to execute

But... While I export applet in exclipse I can use it without any browser, just like application(as I and avarage user knows it).

Ok, I understand difference like "Applets cannot read from or write to hard disk files."

So. What should I use while creating what?

For example, something as simple as windows calc, some 2d simply platformer, some more expanded app, like idk, spotify or media player or whatever?

Since after update 51 of java web applets are nearly useless(as I know, maybe I'm wrong?), what is better?

Can application have GUI or it is only applets thing(stupid question?)?

Where can I find any application tutorial? Everything that I found was for applets. Why?

How To Launch Applet Through Other Than Web Browser

Apr 6, 2014

know if you can launch an applet through other means, other than web browser or through the Eclipse.

You know when you write an applet in eclipse you just extend a class and you hit Run (application) and the applet launches.

Or you can export the applet and run the applet from a browser.

Is there another way, to launch an applet like you would a JFrame?

Or the ways I just mentioned above are the only absolute ways to launch an applet?

Converting A Program Into Applet?

Sep 30, 2014

how to make an applet out of this program but can't seem to do it.

Java Code: import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.JLabel;
import javax.swing.JFrame;
import java.io.*;
import java.util.Scanner;

[code]....

Technically, when you run the program, a gif page appears (that I put as a placeholder) and when you press the letter 'n' JCreator runs the program, displaying a character P on a .txt field made using the Notepad on Windows. You can move it left, right, down, and up andf it will move accordinly. However, each time I make such action, the compiler has to rewrite to whole .txt field with the new position.

My former tutor said that in order for it to be "real-time", we have to use an applet.
