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

Jan 16, 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). Someone suggested to me to use this custom stretch icon class, found here:

[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 implementation of it, and how would I fix this?

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();

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.

Resize Window To See Programs

Jan 21, 2014

Whenever I make something in Swing, I always need to resize the window for me to see the graphics on the window. I have been told to use the pack() method on it, which I have, but the problem with it is that it just sets the window to a minimal size, only displaying the x + and -.For one of the "games" I made, it at first didn't work until resize, then I added a repaint() after the constructor and it worked for me, but when my friends download it they cannot see it.

JavaFX 2.0 :: Drag Events Destroyed By Window Resize?

Jan 24, 2015

I've been having great success developing a drag-drop component for a JavaFX app, but I've run into an issue that has me completely stumped.
 
Specifically, I create a component that can be dragged around inside an anchor pane.  That anchorpane is nested in a split pane, which is nested in another anchor pane (the control's root element).
 
The issue can be described this way:
 
Case #1:  If I start the application as a small window, I can reposition the control by dragging it around the screen as I please.
Case #2: If I start the application and maximize the window, again, I can drag the control around the screen as I please.
Case #3: If I start the application, drag the control around a bit, then resize the window, the drag event handling breaks as follows:

1.  The control drag events will fire normally only within the bounds of the anchor pane's previous size.
2.  The mouse cursor's drag icon changes as I pass in or out of those bounds
 
I'm absolutely certain the anchorpane is resizing to match the parent window, otherwise Case #2 would not succeed.  I'm at a complete loss as to determine why the drag events don't fire within the bounds of the resized window after they've been fired within the bounds of it's previous size.
 
Understand the mechanism I'm using to establish the drag handling:  Once the controller is instantiated and added to the scene, an event listener on the class's parentProperty fires to attach the drag event handling to the parent node.
 
Previously, I was setting / clearing the drag handling on the parent node in the drag detection / drag dropped event handlers.  I had suspected that adding / removing drag events was causing the trouble and opted for this solution to ensure that the same event instance was being used each time.  Both methods have had the same result.
 
If you want to see the UI in action, here's a youtube link (it does not demonstrate the problem I'm having):
 
[URL]
 
Here's the code that I'm using, redacted for clarity:
 
public class FileSystemNode extends AnchorPane {
@FXML private AnchorPane fs_node_title;
private FileSystemType mFsType;
private Point2D mDragPoint;

[Code]....

Program To Change Colors Of A Shape In Other Window

Feb 13, 2015

I was working on this project, and I have everything working, except that it doesn't change the colors of the shapes in the other window. Here's the code to see what I'm doing wrong:

Java Code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JDemo {
//Global Variables
static Color color0 = Color.blue; //sets the value in the color0 variable to the method Color.blue .
static Color color1 = Color.red; //Sets the value in the color1 variable to the method Color.red .

[Code] ....

The button0 is supposed to switch the color in window1, and button1 is supposed to switch the color in window0.

Swing/AWT/SWT :: Icons Should Drag Starting At Point Where Mouse Originally Clicked Down

Apr 23, 2014

I am working on a simple app that should emulate a desktop with some icons that you can drag around. I was instructed to use the MouseListener and MouseMotionListener. The icons should drag starting at the point where the mouse originally clicked down on it (ie not dragging from the top right corner).

I am drawing my icons to a jpanel, and I seem to be having two problems:The hitboxes are offThe icon is being dragged from the top right corner, despite having setup up a mouse offset at the beginning of the drag..Here are the relevant classes, the Desktop.draw() method is being called from my DrawPanel

Swing/AWT/SWT :: Flickering On Resize

Jan 12, 2011

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.

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.

Swing/AWT/SWT :: Displaying PNG In A Window

Jan 31, 2014

That's my third day working in Java using Swing and the IntelliJ Idea IDE.I'm trying to do something as simple as displaying a PNG in a window, and I'm doing this:

public class AboutRapide {
public JPanel mainPanel;
private void createUIComponents() {
mainPanel = new ImagePanel();

[cod]....

the problem is that, in the paintComponent method, the Image is never found when I run my app from the IDE, but it is when I run it from Finder in my Mac. Same application. I think it relates to how the application is launched so I guess what's a proper way to refer to a resource file with an image so it can be displayed no matter how the application is launched?Also if I generate a Jar for the application, as the resource gets into the Jar compressed file, it can't also be loaded.

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;
