Swing/AWT/SWT :: Resize Application Depending On Screen Resolution
Sep 26, 2014
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 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'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.

This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.
public void actionPerformed (ActionEvent e){
if (e.getSource ==add) {
if (text.getText().equalsIgnoreCase("Exam Schedule")){
link1.setText(text.getText());
link1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
[Code] .....

I need to create a program that draws a graph, but for now, all I have done is two lines: the X and Y axis. The program is designed in a way as to automatically resize the graph when the window is resized.
Is this code in some way extremely inefficient? I get TERRIBLE flickering when I resize the window. Is there something that will at least reduce the flickering?
mainApp.java:
import java.awt.*;
import javax.swing.*;
public class mainApp {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setSize(300,300);
frame.setVisible(true);
[Code] ....
I have added a screenshot that shows the window flickering.

I have a problem with my program. My aim is to display in a JPanel, 2 rectangles from an arraylist, and resize them by clicking. I want to give the user the ability to change the height of the rectangles (independently) by moving the top and/or bottom edges. There is errors in my code but where ? Netbeans underlines 2 lines (in bold).
My code:
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.Path2D;
[Code]....

I have swing UI designed and I want the components to resize when the frame is manually resized. The design is as shown in the fig Project UI.jpg
The panel 4 and panel 5 will change their contents according to the list item clicked. Panel 4 just has text area but panel 5 a panel with numerous components as label, combo box, text field,check box will be present.Now if the frame resizes, I won't all the components to resize according to the frame size.

Lets say the JDialog opens 5x5. The user is allowed to modify its size to be any size larger than 5x5 but is not allowed to make it smaller. Is there such a property or will this have to be regulated via code?

Is it possible to allow users to resize columns in a JTable that has no header? I'd like the user to be able to grab the column lines on any of the data rows and be able to resize just like they can in the header.

My JPanel when adding components to it will never make its self larger but it will make my components inside smaller even though I have set the minimum and preferred sizes for those components? I am using the GridBagLayout for my layout manager as I am trying to get used to it.
package manning;
import java.awt.Color;
import java.awt.Component;
import java.awt.Dimension;
import java.awt.GradientPaint;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GridBagConstraints;

I'm using a jpanel with an 8 by 8 grid layout of jlabels to which I'm adding images to represent a chess board. At first, I was using the ImageIcon class to initialize my icons, but as soon as I added these icons to the labels, the labels no longer changed size with the window (which I want to happen). URL...
So I copied in the class, and initialized a different set of icons using the stretch icon class (specifically, the method that allows you to initialize a stretch icon from a filename), however, when I use these stretch icons, the result is the same. Is something wrong with the class, or with my implimentation of it, and how would I fix this?

I'm trying to create a chess program in java swing, and for the board I'm using an 8 by 8 array of jlabels stuck inside a jpanel with a grid layout. I would like the board to change size when the window changes size, and the grid layout accomplishes this succesfully, until I add the actual icons to the jlabels. Then the board just stays a fixed size. Someone suggested I use their "Stretch Icon" class, found here:[URL] ...., so I tried initializing the icons using one of the constructors in the class (the one that takes an image name and a boolean value for whether or not you want the resisizing to be proportionate (to maintain the aspect ratio)). However, the same thing happened. The board appears, but it does not resisize. To attempt to fix this problem, I tried simplifying my code, reducing the program to two jlabels within the jpanel, for which I then tried to set the image in the same way. Here is my simplified code:
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.ImageIcon;
[Code] ....
I'm misusing the stretch icon class, or just generally what's going wrong/how to fix it?

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);

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?

Image image1 = ImageIO.read(this.getClass().getResource("body.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'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 would like to be able to change the locale in my Swing application at runtime and have all the text elements on the GUI update themselves with localized text from a ResourceBundle of the new locale.If there a simple way of achieving this without having to create an event model for all GUI pages?

I am writing a Java Swing GUI application on my pc. I have to give this application to my cousin with another pc, where he is not aware of programming. then how can he execute that application? are there any ways of skipping the "javac" and "java" procedures while executing the app on his computer?
I am using win7 x86 and same at my cousin's place. I am also using eclipse-kepler sr1 ide for app development.
Are there any easy ways of automating this "javac" and "java" process(compilation and execution)? something like...scripting?
