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.
View RepliesI'm not understanding why the Jtextfield and Jlabel are not appearing on the dialog window.
public class CreateQuote extends JDialog {
private final JPanel contentPane = new JPanel();
private JLabel interestRate;
private JLabel numberofYears;
private JButton tupac;
[Code] .....
When i run the program it doesn't show all the text fields and labels and stuff but when i click btnTest_1 and go back to btnTest everything appears...
Java Code:
import javax.swing.*;
public class Frame extends JFrame{
private JTextField textField;
private JTextField textField_1;
public Frame(){
setTitle("Multifunctual Calculator");
[Code] ....
What should be the code if i want to input a different string in case of the typed string. The case is : I have a predefined string S = "Peter,please answer my question" and now when i input another string inside the text field character by character i want characters from the string S to enter instead of the input string. In short, the input string should be disguised as string S.
View Replies View RelatedI have an addressBook GUI where I have a JList that populates with the contacts names, and once I double click a contacts name I'm wanting to fill the textfields with the contacts corresponding data.
ex) ContactType: Family (enum), Name: Zoidberg, Address: 111 Space Drive, City: New York City, etc...
I've got it to where I select open from the JMenu, it populates the JList, but once I select a contacts name, all the textfields are populated, but only with the contacts name
ex) Name: Zoidberg, Address: Zoidberg, City: Zoidberg, etc....
What am i doing wrong here, and how can i fix it to where it fills out the correct data?
Here's my code so far:
public class AddressBookGUI extends JFrame {
private final int WIDTH = 450;
private final int HEIGHT = 300;
private JLabel currentlySelected;
private JTextField contactTypeTextField;
[code]...
I'm certain the logic is messed up near the end where i set all text fields to the index, because no matter what field i want to fill it's at it's going to set it to whatever index I select, but I don't know how to fix it.
I am able to generate text boxes. But I need one specific thing in that:
Through a drop-down I should select a number and those many text boxes should get generated.
Suppose I selected 4 from the drop down list. Then on screen it should display:
Student 1: Textbox
Student2: Textbox
Student3: Textbox
Student4: Textbox
I am trying to use JTextField. I have windows 7.I have jdk 8u45. I am trying to use multiple text boxes. I have written the following code:
import javax.swing.*;
import java.awt.*;
class Avg5Nums{
int num1, num2, num3, num4, num5;
double Avg;
Avg5Nums(int val1, int val2, int val3, int val4, int val5) {

I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField. I have made multiple tweaks, but think maybe my case statement is the problem?We did a calculator application in the class, so I have based my code off of that. Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.
public void actionPerformed(ActionEvent e) {
//test for button clicks
foundKey = false;
//search for clicked key
for (int i=0; i<keys.length && !foundKey; i++)

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]....
Here is the code..
package KOSAR2;
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;

I've created a chat program, but now I need to show messages in different colors depending if the message is received or sent. I was wondering if I can use jlabel to do this but in this case I need that jlabels to scroll in a jpanel. how to do this or maybe using a rtf ?
View Replies View RelatedI have a popup that displays textual info and sometimes gets text input from the user. I'm using the following code:
JTextArea textArea = new JTextArea( getGameHistory( true, -2 ) );
JScrollPane scrollPane = new JScrollPane(textArea);
textArea.setLineWrap(true);
textArea.setWrapStyleWord(true);
textArea.setFont(new Font("courier", Font.PLAIN, 12));
scrollPane.setPreferredSize( new Dimension( 30, 100 ) );
String input = JOptionPane.showInputDialog(null, scrollPane, "Fun Chess ",
JOptionPane.YES_NO_OPTION);
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?
From what I can determine check boxes are applied in SWT to the first column only of a table.
final Table table_project = new Table(g3_tabfolder_projects, SWT.BORDER | SWT.CHECK);
However I require check boxes on all cells. I tried creating a table for each column (which gives me my check boxes) but as the number of enries are often numerous and thus require vertical scroll the tables become out of sync (and to the user that sync is important).
Before I knock up some code to try and synchronise the tables I just wanted to check any alternative approaches. The project is SWT based.
I wrote a simple random spelling game for a class project, was never able to get the labels to update when they should. I have tried .updateUI, .paintImmediately followed by .revalidate and by .repaint. Nothing seems to be working.
What the game does is show a random word for about 10 seconds, disappear and they user is to spell that word, you have 3 tries then will start over. The "brains" of the game work just fine, it is the labels updating with new text when they should doesn't seem to be working. There is 4 classes but the below is the "Main" that has the problems. Also have a null exception problem with the timer.stop(); not sure why. I am still pretty new to java.
Public class SpellMe extends JFrame {
// variables
JPanel mainPanel, secondPanel, thirdPanel;
JLabel mainLabel, wordLabel;
String spWord, sp;
JTextArea guess;

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?

I have list of employees in my database and their associated information like employeeId,supervisor and process. I have class named EmployeeDetails having same properties. I am fetching details of all users using below code:
<%EmployeeDetails employeeList;
employeeList=(List<EmployeeDetails>)assetmain2.getEmployeeList(loginName);%>
<table>
<tr>
<td>
Requested For <select name="requestedForName" id="requestedForNameID">
<option selected="selected">--Select--</option>
<%int i=0;
[Code] .....
In employeeList, we have list of objects having data of employees. I donot know how to get which object is selected in dropdown and based on that rest of the text fields are populated. Example:
Name ID Supervisor
-------------------------------------------------------
Pawan Kumar3033045Vimal Kumar
Vimal Kumar3040901Dinesh Hemrajani
If Pawan Kumar is selected from dropdown then '3033045' and 'Vimal Kumar' should get populated.
Many times I have read that JSF stores de view state in session and one of the things that are stored are the values of the form fields, right? But these input field values are not stored in session, I mean, they depend of the scope of the managed bean attached to the view. If I have a view and its attached to a view scoped bean with properties for the form fields, the values will dissapear if I go to other view because the bean is view scoped so I cant say the values of the form are stored in session, right?

View Replies View RelatedVariable Fields are not holding information through constructor from user input so here's what I did instead.
View Replies View Relatedhow to differ between fields that are not exists to fields that are null? because in my api when someone wants to delete a field he sends null instead of a value. and if he doesnt want to effect this feild he doesnt send it.

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.
// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;

There are several ways in Java to create a text file and write to it. But which is the most effective way among them? Any example with code?
