Basically the code is for a game which is displayed in a window. The statement if(false) //full screen mode is confusing me a little. How does this if work? it doesn't seem to be testing for anything so how does it ever get set to full screen mode? Is the if even needed? why not just code windowed mode?
public class Window extends JFrame{
private Window()
{
// Sets the title for this frame.
this.setTitle("My test");
// Sets size of the frame.
if(false) // Full screen mode
[Code] .....

The code:
import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.BorderPane;
[Code] ....
run (when window height > 700px ) :
HTMLEditor default height is 670px, the other area (green color) is not filled,why?
HTMLEditor 高度总是670px, 怎么把HTMLEditor 填充满窗口?
这是一个bug吗？
is it bug？

I am trying to create a JScrollPane with buttons in it, but I noticed that when I try to scroll, the items all move into ONE row at the top of the JScrollPane. How do I have them vertical? Is there something wrong with the way I am setting up the JScrollPane?
private static void addScrollPane() {
jScrollPane = new JScrollPane(new JPanel());
((JPanel)jScrollPane.getViewport().getView()).add(new JButton("First Button"));

I have created a java gui on Windows 7 with Eclipse EE, using a screen resolution of 1366 x 768. I used groups with specified boundaries. For example:
final Group g5_script_data = new Group(shell, SWT.BORDER_SOLID);
g5_script_data.setText("Current DB");
g5_script_data.setBounds(0, 0, 680, 380);
g5_script_data.setBackground(green);
The groups cover the whole screen.
However my colleague with a smaller resolution looses the far right of the screen.
As this is a proto-type and I'm new to Java I don't want to rework everything or convert it to say a grid layout until the proto-type is accepted and I can start from scratch with a real detailed design. It already has 6500 lines of source.
Just wondered what is my quickest/easiest way to get my app to display on a slightly smaller resolution. For sure it will not be anything silly. Something like 1280 x 768 to 1366 x 768 would do.

I had developed small GUI using swing group layout, which is nice to see on windows, but when I tried it on Linux the GUI look is varied. Then I set the GUI height and width by taking screen resolution, still it is varies the screen look. How I can make the GUI such that it looks the same on all screen resolutions.

I'm writing my first bigger program (mysql connection and the first thing bigger than 300 lines ). What I'd like to do is to render data from MySQL using JTable - I managed to handle all the queries but I don't know how to update the table on screen. I've tried to use repaint() but nothing happened. I'm not posting whole code because you'll probably not interested, below are the most important things. I thought about using TableModel but how.
public class Main implements ActionListener{
JTable table;
public Main() {
JFrame frame = new JFrame("Frame");
frame.setLayout(new FlowLayout());
frame.add(table);
[code]...

I am trying to drag the window down wards and screen has alignment issues. I tried to use WindowListeners, Component Listeners, MouseListeners ect…
But still this problem persists as only I release the mouse after drag down it appears fine that we have handled ComponentResized() method. So how to restrict component size while keep dragging down?

public void DrawSnake(Graphics g) throws IOException {
Image image = ImageIO.read(this.getClass().getResource("body1.jpg"));
Image image1 = ImageIO.read(this.getClass().getResource("body.jpg"));
Image headr = ImageIO.read(this.getClass().getResource("headr.jpg"));

I want to build a class that takes a JTable and previews on screen how it will be printed on the default printer. This is what we use to call as "Print Preview", just like MS Word, Excel, etc. As we already know Java does not support this functionality out-of-the-box.
Based on some examples I've found googling I built two classes. The first one TestPreview.java justs shows the JTable and the second one PrintPreview.java previews how the JTable will be printed on the printer.
I have two buttons to go through the pages, "PREV" and "NEXT" and "Print' button to print the JTable. My problem is that when my JTable has too many rows and spans in more than one page PrintPreview does not work. It shows the same page again and again. Also, it does not show the entire JTable data, but only some of them and I can't figure out why.
Below is my two classes.
TestPreview.java
package printpreviewdemo;
import javax.swing.*;
import java.awt.BorderLayout;
import java.awt.FlowLayout;
[Code] ....
Below are my screenshots.

I've got to make a ball bounce around a screen.... From what I can gather they seem to hold back useful java code.
anyway, i've changed the code over and over, and think this is the most succinct way i can manage it. but i have a problem. where i've marked the code (*****) and the following line are conditional on each other. so one won't provide the correct answer without the other line executing first, and vice versa (ignore the code after, i haven't looked at where that should be yet ). Anyway I don't really want to rip the code apart, again, because i'm pretty sure it's close.

I developed a swing application using group layout. It resizes when I resize the frame but when I change the screen resolution or when I run the application in a laptop which has small sized screen, the components over lap each other. I need my application to fit according to the screen resolution
The code is as follows
private void initComponents() {
jComboBox1 = new javax.swing.JComboBox();
jButton1 = new javax.swing.JButton();
jButton2 = new javax.swing.JButton();
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
jLabel3 = new javax.swing.JLabel();
[Code]...
According to the list item selected, an internal frame will appear in the desktop pane. I use group layout for that internal frame too.

I'm working on Ubuntu with resolution 1600*900; I used MigLayout to place the components of the application; but when I go with higher resolutions,components adjustment and alignment are not up to the mark.

I'm making a game of checkers for my A2 Computing coursework which is due in within a week. I have completely finished the game, and only thing I have left to do is connect the two JPanels together via a CardLayout that I have made. However I am unsure how to do so
Here is the code from my CardLayout:
import java.awt.BorderLayout;
import java.awt.CardLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.ItemEvent;
import java.awt.event.ItemListener;
import javax.swing.JButton;
[Code] ....
I have kept the code I am displaying to a minimal, hence I have removed all the action listeners for my buttons, anyway the problem I have is that, I would like it so that when the user clicks on the 'Multiplayer' button which is the array button ourButtons[1], it will then transition into my main game screen so that the user can then play a game of checkers.
Here is the main important GUI from my CheckerBoard class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class CheckerBoard extends JPanel implements ActionListener, MouseListener {
// Main routine that opens an Applet that shows a CheckerBoard
public static void main(String[] args) {
new CLayout();
[Code] ....
Once again kept to a minimal.

I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.

I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
Code before:
<td><input class="buttonred" type="submit" value="Confirm Add" name="submit_message"></td>
<s:form action="upd-message" method="POST" validate="true" onsubmit="validateMsg();return false;" enctype="multipart/form-data">
function validateMsg() {
var frm = document.forms["upd-message"];
frm.actionType.value=message;

I'm trying to make a canteen class that holds water. It holds two quarts of water and two quarts is 100%.
public double maxVolume;
public int percentFull;
Right now the Canteen is empty.
public void Canteen()
{
percentFull=0;
maxVolume=0;
}
And right now I'm trying to make a constructor that specifies the amount of liquid the canteen can hold and specifies the percent full.
public Canteen(double maxVolume, int percentFull)
{
}
Should I make this second Canteen an integer, a double, or something else? Also, how do I make sure the Canteen never reaches higher than 100%. I'm also curious how I can keep maxVolume and percentFull connected so the % of water is consistent with the number of quarts(2) the Canteen can hold.
