This shows a nice text area and an input field underneath it.The getGameHistory() method just returns a long string detailing the current game.Is there a way of just showing the text area without the input field underneath?Can the text area also be used for input instead?
I am building a chat server/client and would like to have it so when a user sends a message, the message pops up in the main chat area beside their name, which I would like to be in bold font. Something like "Alan: Hello, how are you?". I can't find a way to do this with a text area or on a string. Do any swing components suitable for use as text areas support bolding of certain sections of the string that you will set to it?
This is the code that I wrote but I have two problem with two buttons one of them ... I want to delete the selected text inside the text Area which represented as b[8] and the other button that I want to select parts of the texts which represented as b[0]....
I'm supposed to write a GUI application letting the user enter a file on the text field and display its hex representation in a text area and vice versa.
Here's my code:
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package hexconvertor; import java.util.*; import java.io.*; public class HexConvertor extends javax.swing.JFrame {
I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.
I'd like to change the text on the two buttons which I have in my Dialog Box, how should I do this?
Also, when I click the X Button in the top right of the Dialog Box, nothing happens, and the program only stops when I end it in jGrasp. How do I make this button close the program when clicked on?
import javax.swing.*; import java.util.Random; public class SwingInputExample { public static void main(String args[]) {
How to create text fields, labels and input boxes on a GUI, we haven't covered these in class as of yet, but I want my project to stand out so I'd like to know how to build a GUI now.
how to put the output the the text area this is the code .
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package interns; /** * * @author JosephP */ import javax.swing.*; import java.awt.event.*; import java.awt.*;
I have a requirement where in the content of the text area is dynamically populated from the database. I am able to successfully retrieve and display the data on the text area.
However when the content is too large, I am not able to dynamically set the height of the text area. When I try to display the same as a label, the display is flawless, dynamically sets the height as per the content. So, I tried to create a label, with same content and dynamically bind the height to the preferred height as below, but it doesn't work.
// Generate User Note Description TextArea textArea = new TextArea(); Label text = new Label();
// SETTING THE TEXT TO A LABEL TO RETRIEVE THE HEIGHT text.setText(usrNotes.getNote().trim());
How can I read a text file present in my local directory say (C://test.txt) , iterate and populate the values of test.txt into a text area of the JSP page?
Contents in the test.txt file: username:test password:test123 domain:test321 DBname:testDB
I have problem with my simple program. I tried put some text in my text area using button1 but textListener in RighButtons is always null and it's give me NullPointerException.
WriteToArea - interface public interface WriteToArea { public void add_a(String text); } BaseFrame public class BaseFrame extends JFrame{
In my application, some text should be added to a text area in response to a click on a button. So as an action listener to this class, I made another class which implements the ActionListener.
Inside this class, I have obtained the text which I want to be added to the text area. But the text area is in another class and for the action listener I wrote another class.
Now the problem is that when I try to add the text to the text area by the following line of code, it says that textArea_1 can not be resolved or is not a field.
Java Code:
ParentPanel.textArea_1.setText("Name:"+ncrarray[0]+" Code:"+ncrarray[1]+" Rank:"+ncrarray[2]); mh_sh_highlight_all('java'); What should I do about it?
Even if I try to write a method like the following in the class in which the text area is created, it gives the same error.
Java Code:
public void printTextArea(String text) { textArea_1.setText(text); } mh_sh_highlight_all('java');
The text area is present inside a constructor of the class. I am writing the method outside the constructor (ofcourse).
I have to write a gui program where I can enter a file name and then it gets displayed in a text area when I click Open. Conceptually, I do not get this. I was thinking of appending the text file into a string or something, but I guess I'm confused on how it all works and how I can open the text file. Not asking for the code, but just a compass or something.
I am stuck on one of the projects: Area Calculator
I am able to code an area calc that works, but am unsure how to move all the input/output to main like the project wants. here is a piece of my code so far:
I have the same thing for rectangle, square, and circle (of course with the correct formulas) and the program works perfect, but the assignment is still wrong until I can move the input/output to main. what do I do?
Create a program to input the length and width of a rectangle and calculate and print the perimeter and area of the rectangle. To do this you will need to write a Rectangle class and a separate runner class. Your program should include instance variables, constructors, an area method, a perimeter method, a toString method, accessor and mutator methods, and user input. Your runner class should include 3 Rectangle objects. One default rectangle, one coded rectangle, and one user input rectangle. All methods should be tested in the runner class.
This is my code:
import java.util.Scanner; public class Rectangle { double length; double width; public Rectangle() {
[Code] ...
What have I done??? I have created this program using the few different resources with which I am supplied, but I don't understand the resources.
The problem I'm trying to resolve now is getting my ActionEvent to send the value input in the JTextArea out to be calculated, then to display the result in my result JLabel.
Here is an image of the GUI :
The basic procedure the teacher is asking for is the user is supposed to enter a temperature in the input. The user then clicks the input scale, and then on the output scale selection the converted value is to be displayed in the output area.
As I mentioned my problem is in the sending of the input value to my calculation area, and getting the value to display in the JLabel.
How should I approach this solution? Do I need to have a listener after the JTextArea of the input box? Will that allow me to limit the input values to numbers only?
final JTextArea inputText = new JTextArea("" + (char)176,1,4); //ReadConsole equivalent to specific input was a number?
Here is the section of code my ActionListener is:
//celOut represents the Celcius output scale JRadioButton. celOut.addActionListener (new ActionListener () {
@Override public void actionPerformed(ActionEvent e) { //if the Celcius Input Scale is selected. if(cel.isSelected())
[Code] ....
All the calculations are required to occur in a separate java file, which what I think is tripping me up. How do I send a value from the JTextArea into the Calc.celToFahr method?
//contents of my Calc.java calculation class. public class Calc { public static double celToFahr(double cel){ return cel * (9./5.) + 32.; } public static double fahrToCel(double fahr){ return (fahr - 32.)*(5./9.); } }
I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
I try to create Java Swing Desktop application which show Road map of some area in JFrame. But pc not connected to internet it will be in LAN. Map should be like if we scroll the mouse we go down from height in map. Like zooming the area.
I try to find out by google i get lots of forum links but each showing me.
1. I have to do web application. 2. Google not support 'without internet' map facility. 3. I should use lots of jpgs which store in folder for showing map from various height so it look like when we see any map in Google Earth application.
I found goworldwind.org but not clear understanding right now.
I have a textField in which I have text in. The text is enter customer name. I would like for this text to disappear whenever the user clicks on the textField to enter a customer name. I am using the automated swing gui builder in NetBeans. Is their some sort of feature for this under properties of the text field? If not then what are my other options?
I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException { int returnVal = fc.showSaveDialog(window); if (returnVal == JFileChooser.APPROVE_OPTION) { StyledDocument doc = (StyledDocument)text.getDocument(); HTMLEditorKit kit = new HTMLEditorKit(); BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
Is there any way to use scanner to get input and distinguish between int and text? I'm trying to make a scanner method I can call whenever I need user input no matter if I need int or text. Using two methods (one for int, other for text) at the moment.
import java.util.Scanner; public class Application { public static void main(String[] args) { Person person1 = new Person(); System.out.println("What is your name?");
I'm attempting to compare user input to a text file that I have set up whenever the user types in an employee ID number. I want to be able to tell the user that either the ID number is valid, or that it is not valid and must be re-entered by comparing it to the employee.txt file, and then record the valid ID number to the timeclock.txt file. I'm recording the next available employee ID number instead of the one I typed in. The output of the program looks like this: i82014/06/06 12:16:56 (I typed 1 as the employee ID.)
