Swing/AWT/SWT :: Revalidate Is Resetting JTextArea Position On JPanel

Nov 3, 2014

So, I have a program that allows me to dynamically add JTextAreas and then drag them around the screen. The problem is, when I add a new JTextArea, I call revlidate() to update the panel. This causes all of the JTextAreas to reset their positions. How can I prevent this from happening? It is happening on this code:

public void addBox() {
drag = new DragListener();
JTextArea textArea2 = new JTextArea("Some text
Some other text");
textArea2.setLineWrap(true);
textArea2.setWrapStyleWord(true);

[Code] .....

Swing/AWT/SWT :: JTextArea Position And Size

Nov 6, 2014

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 :: How To Implement JTextArea In Netbeans

Apr 20, 2014

I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:

//{
Import java.swing.*;
JTextArea txa = new JTextArea();
txa.getText(jTextArea1);
txa.setText(jTextArea1);
txa.setTextWrap(true);
//}

Swing/AWT/SWT :: Using SetBounds Or SetLocation On JTextArea Not Working

Oct 31, 2014

I am adding a JTextArea to my JPanel with this code:

commentTextArea.setLineWrap(true);
commentTextArea.setWrapStyleWord(true);
commentTextArea.setVisible(true);
this.add(commentTextArea);
commentTextArea.setBounds(0, 0, 100, 100);
//commentTextArea.setLocation(0, 0);

Whenever I use setLocation(0,0), the JTextArea never moves. It is always in the top middle of the screen, not at (0,0). The same goes for setBounds(0,0,100,100) BUT the height and width are set this way, just not the location. Why is this?

Full Code

import java.awt.Color;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JMenuBar;

Swing/AWT/SWT :: Save Text From JTextArea - String Formatting

Dec 30, 2014

I am currently working on a project that can save text from a JTextArea and also open that same saved text. The problem I am having is that when I open the saved text file it is no longer formatted.

How the file looks before saving/closing:

public class HelloWorld{
System.out.println("Hello World!");
}

How the file looks after being saved/closed then opened:

public class HelloWorld{ System.out.println("Hello World!");}

When I save the file I'm actually saving the entire thing to a single string. When I do this the String eliminates all tabbed spacing and pushes all characters to one single line.

The only ideas I had for fixing this were to either somehow use Format in the String class or record every time user tabs and add to the String.

Swing/AWT/SWT :: Give JTextArea Focus - Using It On A Panel And With JToolBar

Apr 21, 2014

I have a program with a main panel JPanel that implements KeyListener. I added a JTextArea to which I added as the KeyListener: this, meaning the main panel. I made the JTextArea fill the entire main panel because I want to catch a key press anywhere in the main panel.I catch the key presses and the program does what I want it to.

I added a JToolBar to the program; it is working just fine.Now that I have two components on the main panel - toolbar and panel with textarea -, the textarea must have the focus before it will send the KeyEvent and call keyPressed(). I don't want to expect the user to click on the main window to get the program to start or after each time they use the toolbar.

I have tried calling both requestFocus() and requestFocusInWindow() on the textarea; neither call worked. I put the toolbar at PAGE_END instead of PAGE_START; this worked to allow the program to start but I don't want to have the toolbar at the bottom and once I clicked on a toolbar button, the textarea lost the focus.

I need to be able to give the textarea the focus when the program starts and after the user uses a toolbar button. (I suspect that if I solve the problem when the program starts, I can use the same method after handling a button press.)

Swing/AWT/SWT :: 2D Spaceship Game - Image Rotation And Position

Aug 29, 2014

I'm attempting to create a 2D spaceship game from scratch. My problem is that I feel like the way Im rotating images is awkward and just wrong. I believe what I'm doing in the following code is loading an image into a JPanel and rotating the image and moving the JPanel.

The code is unrefined and only partial, but it show how I am manipulating images.

import java.util.*;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.awt.geom.AffineTransform;
import javax.swing.*;
import java.lang.Math.*;
import java.io.*;
import javax.imageio.*;

[Code] .....

What seems so awkward is that I have to create a new JPanel for every image, I would think there is a better way but I don't know. I have tried to get one image on top of an other with the JPanels to no avail. That said I haven't put much time into trying to get that to work. I want to know if I should continue my attempt with JPanels or to pursue a different method.

Swing/AWT/SWT :: Rows In JTextArea - Entering More Lines Than Limit

Jan 9, 2014

Here's a snippet of code from a program I'm making:

private void init() {
...
testInfo = new JTextArea("Progress log:
");
testInfo.setEditable(false);
testInfo.setLineWrap(true);
testInfo.setPreferredSize(new Dimension(testInfo.getPreferredSize().width, 200));
scrollPane = new JScrollPane(testInfo);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
...
add(scrollPane);
}

The problem is, the JTextArea that's created has a "limited" number of rows - it seems you can still enter more lines than the "limit", but they don't show. I thought it was a problem with the JScrollPane but I'm not so sure...

Swing/AWT/SWT :: Java Stop JScrollPane Auto Scrolling Back To The Top When JTextArea Updated

Feb 7, 2014

I have a swing application that gets football scores from a website using Jsoup.

When the "Get Scores" button is pressed, the scores are printed to a JTextArea with a JScrollPane.

I have also used a SwingWorker to update the scores every couple of seconds.

My problem is that every time the JTextArea updates, the JScrollPane scrolls back to the top of the text area. I wan the scroll bar to stay where the user left it.

Here is my code (The update is currently set to update every 1 second so you can see what the scroll bar is like).

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.select.Elements;
public class frame extends JFrame {

Pizza Program For Java / Resetting Prices Does Not Function

Jul 26, 2014

I am making a pizza program and most of the program works. I have made an order button that will output the total price of the order. The reset button that I made makes the JTextArea output $0.00, but if I press the order button to make another order, the program does not add the new amount to zero. For example, if I make an order that totals $5.00, but I want to make another order after resetting, the price for the new order will be added on to the previous order's price.

Here is the code. This is a JApplet program. Why the price will not reset? This code was made in BlueJ.

//Author:Kishan Patel

//This is Lab 7, the pizza parlour program.

Swing/AWT/SWT :: Move Focus From Specific Jcombobox To Specific Jtextarea?

Nov 5, 2014

How do I move focus from a jcombobox to a specific component say a jtextarea.

My attempt below seems to be moving to a random component not the desired jtextarea.

takenByCombo.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
dayJTArea.requestFocus(); // focust not moving dayJTArea
}
}
});

I applied the above logic to move focus from a specific jtextarea to another jtextarea as seen below and it works as desired.

dayJTArea.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
monthJTArea.requestFocus();
}
}
});

But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.

Swing/AWT/SWT :: Disabling JPanel And All Its Components?

Oct 8, 2001

Let me explain by simplifying the GUI to a simple frame in which I have a JCheckbox and a JPanel mypanel.mypanel has a Textfield tf,JComboBox cmb as it's components.So now if I deselect the JCheckbox, all the components in the mypanel should be disabled. I used a code like:

[code]mycheckbox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if(mycheckbox.isSelected())
mypanel.setEnabled(true); else
mypanel.setEnabled(false); } });[code]

but the components inside the panels are not disabled. In my actual program I have a large number of different kinds of components in mypanel.So disabling/enabling each of them on each actionPerformed of the mycheckbox will be laborious. Isn't there any way by which I can disable/enable the mypanel to disable/enable all the components in it?
