Swing/AWT/SWT :: Want To Maximize JFrame Size

Apr 13, 2014

I have a simple application where I display a JFrame. I want to maximize the JFrame size, so I have the code this.setExtendedState(MAXIMIZED_BOTH); in the constructor. How do I find the dimensions of this JFrame in its extended state though? I tried this.getSize().Height , this getSize().getHeight() and this.getHeight()? None of them work because they just return a value of 0. And what is the difference in all these statements in terms of what they do?

Swing/AWT/SWT :: Setting Size Of JFrame

May 26, 2014

I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.

import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

Swing/AWT/SWT :: When Maximize JInternalFrame Controls Disappear

Jun 17, 2014

I got a JFrame with its JDesktopPane, and opens a JInternalFrame at the beginning of the execution of the application. That's all fine.

And then, the first JInternalFrame opens another JInternalFrame in its maximum size, and that's when a simple JLabel that I got o the second internal it disapears. Why?

Get ActionEvent When Change JFrame Size?

Apr 8, 2014

I wanted to make a program that would change the color of a circle when I click a button. The problem is that the circle also changes color when I manually change the size of the frame with my mouse. For some reason it trigers an ActionEvent, and i don't know why.

My code is the following:

Java Code: import java.awt.*;
import javax.swing.*;
public class MyFirstGui implements ActionListener {
JFrame frame;

Swing/AWT/SWT :: Adjusting Size Of Box With Mouse

Oct 16, 2014

I'm running the code below which compiles ok using latest version of Java and on Sublime. The problem when it complies the output screen is blank and I can only see the text by adjusting the size of the box with my mouse - and then it colours in black. Code and screenshot below. Is there something wrong with the paint/graf part of the code?

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class BackArray extends JFrame {
int store[] = {2,6,4,8,34,67,19,99,10,12,89,68,45,37};
int xcoord = 100;
boolean firsttime=true;

Swing/AWT/SWT :: Change Size Of Entire GUI?

Feb 4, 2015

I built a GUI and after testing it on various platforms I think I would like to make it bigger by a factor of 2.2 or so.

Is there an easy way to just enter the factor 2.2 and have the GUI change by that factor?

I have over 50 components in the GUI. Ideally each one would just enlarge by the factor including the fonts.

This was my first (and only so far) java program. I didn't know anything about layout managers. I used netbeans and it generated all the code.

Swing/AWT/SWT :: Screen Resolution / Size

Sep 29, 2014

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 need to make a simple applet, but I'm stuck with something. This is how my applet should look:

And this is how that part looks in my applet:

What I've done until now is create one JPanel which includes two other JPanels.. The first one contains only the JTextArea you can see, and the other one includes the other elements.

I just need to make the JTextArea taller, like in the example, so everything comes into place...

Swing/AWT/SWT :: Getting Icons To Change Size With Window Resize

Jan 19, 2014

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?

Swing/AWT/SWT :: JTextField Size Changes With JLabel Text Length

Nov 11, 2014

I want to create 3 JTextFields in a row with all being of equal size.But my first Text field gets so wide than the other two.After adding each component at a time and seeing what causes the problem I realized that if I type a long text for the JLabel that's when this problem occurs.If I reduce the length of the text in the JLabel JTextFields get into the sizes I want. Here's my code

import java.awt.*;
import java.awt.event.*;
import java.lang.Math;
public class Calculator1 extends JFrame {
JTextField value1=new JTextField("0");
JTextField value2=new JTextField("0");

How can I stop the JTextFields changing size when I change the JLabel label1's text length...

Swing/AWT/SWT :: Mini Paint Program - Changing Size Of Shapes

Jun 4, 2014

I am currently writing a small drawing program and I am having trouble with changing the size of the shapes. To do this, I have to access the arraylist shapes, check whether pressedX/pressedY is on any of the shapes in the arraylist using the findShape() method and then when released, uses moveBy() in the Rectangle/Oval/Line class and moveShape() in the miniDraw class to move the shape and draw it in the newreleasedX/releasedY position.

So far I think I have pin pointed the problem to being the method in all the shapes classes, that checks whether the pressedX/pressedY which is the on() method, and the findShape() method in the miniDraw class.

This is the minidraw class

import ecs100.*;
import java.awt.Color;

import java.util.*;
import javax.swing.JColorChooser;

Swing/AWT/SWT :: Automatic Adjustment To Suit Size Of Operators Monitor

Feb 12, 2014

I'm building an application in Netbeans and so far I'm making good progress with it. I have created an animated splash screen in myspacegen.com and then downloaded it as a GUI file. I've then imported it into my application in Netbeans but I was restricted in myspacegens.com to the size of the image I could create. I want to know if it is possible to add code to the splash screen project within Netbeans so that it automatically adjusts to fill the screen. I have used the java commands get width and get height elsewhere in my application so that the window I create in a project automatically adjusts to fill the operator's screen but that has a 'window' to adjust and I do not want my splash screen to have a visible window.

Swing/AWT/SWT :: Getting Jlabel Icons To Change Size With Window Resize?

Feb 20, 2014

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?

Swing - WindowStateChanged Event Updates Window Size After It Completes

Feb 12, 2014

I have a JFrame where some elements (one, for now) have to be centered manually on the contentPane when resizing the window or changing the window state. Resizing event (componentResized) works fine but the windowStateChanged event is causing problems because it doesn't seem to "update" the contentPane's new size properly - it keeps the previous value although the window's size is obviously changed. This can be seen by simply printing the result of getSize called on contentPane.

Centering is done by programmatically changing the constraint of the component (using putConstraint, SpringLayout). The issue is that getWidth used in that method returns "wrong" values which results in an uncentered component. Maybe another listener is needed here?

Additional info: Eclipse with WindowBuilder, Linux Mint 15, Java 1.7

I know about SSCCE guidelines but I cannot make this particular example both ready to compile and short.For unknown reasons, I am unable to post the code example. I keep getting this - "Post denied. New posts are limited by number of URLs it may contain and checked if it doesn't contain forbidden words."

addWindowStateListener(new WindowStateListener()
{
// no "@Override" was generated but it is the same with it
public void windowStateChanged(WindowEvent e)
{
System.out.println("EVENT: " + contentPane.getSize() + ", "
+ getExtendedState() + ", " + e.getOldState()); // amusingly, states are actually correct - interchanging between 0 (Frame.NORMAL) and 6 (Frame.MAXIMIZED_BOTH) when I maximize and "unmaximize"
tfArrayPanelCenter();

Making a JFrame is easy.

Adding a JPanel is a snap.

Swing/AWT/SWT :: Combining Two JFrames Into One JFrame?

Mar 20, 2014

All I need to do is show in just one JFrame the two combined JFrames. One JFrame namely leftPanel will appear to the left or west and the other namely rightPanel to the right or east using BorderLayout. I already did creating them first as JPanels or as internal classes and subsetted them in one JFrame but that didn't work because it looked messy. And now I've created them as two separate JFrames, compiled separately, and tried to subset them as one in the JFrame. I didn't add any functionality to this program because all I intend to do is to show those two JFrames together in one JFrame. Here's the code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class dirtyIceCream extends JFrame {
leftPanel westPanel;
rightPanel eastPanel;
public dirtyIceCream()

[code].....

What am I missing or did I code anything wrong here? Or should I use NetBeans IDE for anything as complicated as this?

Swing/AWT/SWT :: Put A Web Page In JFrame Application

I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :

* import javax.swing . ;

{ public class SwingWebPage
    public static void main ( String args [ ] ) throws Exception {
        JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ;
        website.setEditable ( false) ;

[code]...

If you test , you'll see that the page is displayed in the JFrame is horrible.
