Using JFrame In Java?

Apr 16, 2014

how to use JFrames and button and so on in Java. I found this video on youtube and followed it along, however even though my program is virtually identical to his, I'm still getting errors.

Here's the video I was watching: Video

And here's my code:

import javax.swing.*; //Imports JFrame and JButton for use
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.*;
import java.awt.*;
import java.awt.event.*;
public class swing

[code]....

The reason why I'm importing some many things is I'm trying everything to try fix my problem.

He's the error messages I'm getting:

frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);

[code]....

I used to make the button just create another frame without additional labels but I changed it to be even more similar to his program just to rule everything out. Also initially my program varied quite a bit, I've changed everything to be like his. Even without the ";" error I got, I kept telling me I was not allowed have my class as static, even though the guy in the video has it set to static. Also I don't think my "setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);" is working as it doesn't change color.

I think the problem is with my panel, it isn't adding to the frame for some reason.I'm using TextPad7 and I'm using Win8.

C:UsersWindows 8Documentsswing.java:42: error: '(' or '[' expected
frame2.add(panel);
^
C:UsersWindows 8Documentsswing.java:42: error: illegal start of expression
frame2.add(panel);

[code]....

I would also like to point out that some of the comments are out of date and are referencing the way the program was before I made it just like his. For example I know my second class isn't inheriting the first class.

How To Build GUI With JFrame

Nov 10, 2014

how to build GUI's with JFrame and I was firstly very confused as to when and what is always needed for any GUI in Java. How do I know everything I need for a GUI? Are there certain things every GUI will need by default?

Additionally below I have a code snippet of when this person used the "this" as an argument to a JButton and Im just really confused for when I can use it and when I can't.

public UIStuff(){
super("Multiple Button Events");
init();
} // end multi-button

JFrame - ImageIcon Not Displaying?

Apr 14, 2014

why my image may not be showing. Note I am using eclipse.

Window.java:

import javax.swing.*;
 public class Window {
private JFrame gameWindow;
 public Window() {
gameWindow = new JFrame("Tamagotchi!");

[code]....

I have used file.exists() and this returns true, and file.length() which returns the correct file size.

System.out.println(backgroundImage) returns "splash.png" so thats ok.

Why then is my image not showing?

Swing/AWT/SWT :: Add A Rectangle To JFrame?

Apr 13, 2014

Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?

Making a JFrame is easy.

Adding a JPanel is a snap.

import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TheJFrame {
public static void main(String[] args) {
// TODO Auto-generated method stub

Arranging Layout With JFrame

Aug 7, 2014

I'm just trying to do a simple JFrame class, with standard menubars, labels, buttons, etc. So far, it looks really bad. The only way I can get it to look somewhat decent is if I pack it, but then the GUI is too thin. When I resize it manually, I can get the correct position by sizing it to something specific, but it obviously changes when resized again, and I don't want to set dimensions, if my users are just going to resize it, and mess it up. I want the labels on the left, textboxes neatly to the right of them, and the button somewhere on the bottom.

I also want to dynamically create a new label, textbox and button when they click on "Write File" from the menu bar - I assume this is just done with action listener, but I have enough problems as it is with formatting my layout, that I don't even want to start on it!

import java.awt.Color;
import java.awt.FlowLayout;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;

[Code] ....
