How To Get JTextArea To Display Over The Top
Sep 21, 2014
So I have been working on this code for a bit now... basically just supposed to be a display for a calculator, next week in my class we are learning about how to make it do stuff. so it's supposed to just look right for now. Should look something like this actually
My first question is this, how can I get the JTextArea to display over the top like the example?
My second question is I just started getting an error that compiled before, and I haven't changed anything about this line. Here is everything.
import java.awt.*;
import java.awt.font.*;
import javax.swing.*;
@SuppressWarnings("serial")
public class CalcDisplay extends JFrame{
String[] buttonText = {
[Code]...
the output looked something like this though note this is an old screengrab from while I was working on it. I have since gotten it to color correctly and I have a jtextarea below the numbers. though I need to get it to implement above the numbers and can't figure out how to do so the other example is what it should look like, disregard the color choice.The error I was getting appeared on line 36
Exception in thread "main" java.lang.Error: Unresolved compilation problems: The method setLayout(LayoutManager) in the type Container is not applicable for the arguments (GridLayout) The constructor GridLayout(int, int, int, int) is undefined
at CalcDisplay.addComponentsToPane(CalcDisplay.java:36)
at CalcDisplay.main(CalcDisplay.java:82)
This code has worked through the whole project and I haven't changed a thing.

So currently I am trying to use a JTextarea to display text and I then prompt users to type in certain words. I have a few problems that I have encountered. Firstly when I use setText and then if I say setText again after that it erases the previous text that was set. Ideally I want to set text once per line in my whenever a certain task is fulfilled. For example if the text says enter y/n, I want the program to go to the next line once I say y or n. Another problem of course is when I setEditable to true I can edit the whole textArea. I just want to be able to edit the line which I am currently at. Is there anything that I can use that mimics the ACM console program, or even the console down below in most IDE's where everything appears to be done line by line?
Also here is an example of what I am trying to do, along with comments:
Java Code:
console.setText("Math is good!");
console.setText("What is 2+2?: "); //using getText gets the whole line, I want
//everything checked after the colon. That is where the input will be
if(line==4){
console.setText("That is correct");
}
else {
console.setText("That is incorrect");
}
//previous text lines are overriden with new ones. I don't want that, nor do I want to be able to edit the
//whole JtextArea mh_sh_highlight_all('java');
A JtextArea is just not getting the job done.

I have a JFrame that houses a JScrollPane that houses a JTextArea (I set the console to output to the JTextArea). For some reason, when the frame appears, text is being printed like usual, but the scroll pane isn't rendered unless I hover over it or click on it. Also when I resize the frame, nothing appears unless I hover over it or click on it.
Code:
package voxel;
import java.awt.Dimension;
import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintStream;
import java.util.logging.Logger;
[Code] ....
I've tried repainting the frame when everything is added to the frame and packed, but it doesn't change anything. I tried searching for other people who had the same problem, but most of them were relating to setting the layout to null (which I don't do) and using JPanels.

I created this JTextArea with some text in it. And it also has few variables.
Sth like that:
Java Code:
protected JTextArea textLog;
textLog = new JTextArea();
textLog.append("test: "+variable); mh_sh_highlight_all('java');
And now while I use button that changes variable value, in textLog variable still shows old value.
Tried to use remove(textLog); textLog.validate(); etc(remove, validate, revalidate, add, repaint), because it works fine with JButtons, but still, in textLog variable gives me old value.
like "you should use somethingvalidate(); while clickin button and it will works", not some shit for 3032 lines with 99% of code that I don't need to do what I want.

Every time I load a txt file into a JTextArea it prints the results to the JFrame incorrectly I notice its mainly the white spaces this is happening to. I have tried a few ways to remedy this problem but it still keeps occurring? I've tried append() read() also setText() even Scanner. I have enclosed a picture of my GUI and my txt file I am using.
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;
import javax.swing.JFrame;
import javax.swing.JTextArea;

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);
//}

Basically , I'm trying to make a program that makes the Finch follow the object. I have made two classes :
NewOption52 and FollowClass.
Class NewOption52 contains a method which determines the properties of the GUI. Class FollowClass contains a main method which calls GUI method from class NewOption52 and it also contains several methods which dictates the Finch's behavior alongside with appending text to JTextArea feed.
When I connect the Finch and run the program , a GUI should appear and inside JTextArea should have text which says ""Please Place An Object in front of Finch And Then Tap Finch to Activate!". It didn't happen when I run the program.
Class NewOption52 :
import edu.cmu.ri.createlab.terk.robot.finch.Finch;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JOptionPane;
import javax.swing.*;
public class NewOption52

I am using Swing, I have a JPanel and in it there is a JTextArea and a JButton. I want the JTextArea to move when the button is clicked on. I'm Not really sure how to do the action listener for the button. at the moment the JTextArea only moves once when the button is clicked on, but i want it to move every time the button is clicked on.
This is what i have so far:
moveButton = new JButton("MOVE");
moveButton.setName("move");
moveButton.setBounds(20, 140, 70, 40);
text = new JTextArea("hello");
text.setEditable(false);
text.setBounds(x, 50, 40, 20);
panel.add(moveButton);
panel.add(text);
In the actionPerformed method this is what it does:
text.setBounds(x + 50, 50, 40, 20);
panel.add(text);
text.setVisible(true);

I would like to put the answer of JCheckBox inside of a JTextArea. How to call the answer of JCheckBox if its check the response should be Yes if its unchecked the response should be No, and the yes/no answer should be appear inside JTextArea. But my problem is inside the JTextArea the answer from a JTextField and JComboBox is also there, and they should be appear in a parallel. I attached the physical appearance of the GUI.

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...

So I'm pretty much done with this project except I am unable to get the println statements of "Produced" & "Consumed" to display in my JTextArea on my GUI. I am completely lost as to exactly why the program just continues to create new windows repeatedly crashing. I will include the code to the 3 classes I'm working with - I'm capturing with the fac.println("") on both consumer and producer and have a method in the Factory class that tells it to print in JTTextArea
import java.util.Date;
public class Producer implements Runnable
{
private Buffer<Date> buffer;
private Factory fac = new Factory();
public Producer(Buffer<Date> buffer)

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;

I wish to print the content of a JTextArea. I know I can do this with textarea.print(). However, I wish to print in a different font, font size and orientation from that of the JTextArea itself. I have been able to change the orientation by setting print attributes
PrintRequestAttributeSet printAttributes =
new javax.print.attribute.HashPrintRequestAttributeSet ();
printAttributes.add(javax.print.attribute.standard .OrientationRequested.LANDSCAPE);
And then using the textarea.print() method that allows me to set attributes. However, I haven't found any way to set the font and font size.

I am having trouble with reading specific lines from a text file in to a JTextArea. I want it to read only the first line of my text file and print it out in my JTextArea, however nothing is printing out.
BufferedReader a = null;
try {
a = new BufferedReader (new FileReader ("D:/FinalProjectFile.txt"));
a.close();
} catch (IOException e) {
// TODO Auto-generated catch block

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.

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.)

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...

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);

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;

Write a class named FileDisplay with the following methods:
1.) constructor: the class's constructor should take the name of a fil as an arugment.
2.) displayHead: This method should display only the first five lines of the file's contents
Here is the following code I have made so far
import java.io.*;
public class FileDisplay
{
private String filename;
public FileDisplay(String Filename) throws IOException
[Code] ....
First, in my constructor I have taken in an argument and used that argument to open up an output file. Meanwhile, I'm trying to work n the displayhead method to print out information and to read data to. I haven't opened up my input file yet, but I'm not understand how can I read a print data to an output file. in
public void displayHead()
{FileWriter file=new FileWriter(Filename)}
do I make create another instance of the filewriter class to output data?
In simple words, suppose to I want to display some messages on my output file in the displayhead function. Since I already have opened up the file in the constructor, how do I combine that in this method...
