Swing/AWT/SWT :: How To Make JTextField Editable

Jul 10, 2014

I'm having a hard time finding out the way to make JTextField editable. In what circumstances it can be disabled to write? [even the text in the field can't be selected, not to mention being uneditable. I did the followings to make it editable.

1. In its Properties panel(frame or whatever), checked the "editable" item.
2. In the code I made it run the code below :

void makeFieldsEditable(Boolean flag) {
Left_Name_field.setEditable(flag);
Left_Name_field.setEnabled(flag);
...
}

Is it related with the properties of the control(JTextField)'s surrounding panel, or even the largest containing frame? Using Netbeans ....

Swing/AWT/SWT :: How To Make A Row Of JTable Not Editable

Feb 8, 2014

When I click on a row in a JTable, I want to have a row appear above it. For now I'm just making that row be a duplicate of the row I clicked on, but eventually this will be some sort of previous history of that row, so as you are editing the row you actually clicked on you can look directly above it and see what the data used to look like.

I"m not having any problem creating the row, nor am I having an issue getting it positioned correctly. What I want to do with this added row is made it so you can't edit the entire row, and also really make this row stand out. I'd like to say make this row stand out or "POP" so to speak so there is no confusing what it is. I'd almost like to make it look like the row header or even better... Most of what I am seeing are ways to make particular cells uneditable, so I think my backup plan is that, but Is there a good way to do what I described?

Swing/AWT/SWT :: How To Make JLabel Hyperlink Change Depending On JTextField

Jul 30, 2014

This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.

public void actionPerformed (ActionEvent e){
if (e.getSource ==add) {
if (text.getText().equalsIgnoreCase("Exam Schedule")){
link1.setText(text.getText());
link1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));

[Code] .....

How To Make JTextField To Scroll Down Each Time New Message Received

Mar 31, 2015

I already done a lot of work(user lists, server logging, private messages), but im there is few thing i still dont know how to really implement and, of course my current program is far from beign decent, so i decided to start asking questions(so far i was just experimenting just using knowledge from book and some info found on Java API).

1. How can i make JTextField to scroll down each time new message received and log is already full? i mean visible part of it, so you don't need to scroll it yourself...

2. Why sequencer doesn't play MIDI if it is launched not by main thread?

3. What is good way to do user list with avatars? atm, i'm using regular JList and listening to selected values to open dialogs.

4. What is a good ways to implement sounds in application, other than MIDI? i know that i should just google it, but anyway.

You can check my source code for it by link. Chat client:URL...

Swing/AWT/SWT :: Autocomplete In JTextField

Apr 2, 2014

I have been reading several suggested solutions for implementing autocomplete for a JTextField. However, the documentation is a bit confusing to me. It seems like they mostly require switching to a JComboBox. Can I or can I not continue to use a JTextField and implement an autocomplete feature? I also saw what I thought was a built-in autocomplete "decorator" for swing objects (although it was not clear if it can be used for JTextField) but most of the implementations seem to start from scratch. Any simplest way to implement this (assuming those 2 conditions are not mutually exclusive)?

Swing/AWT/SWT :: How To Get Data From JTextField Over To JTable

Jun 20, 2014

I am trying to get the data entered in a JTextField into a JTable but not clear on how. The LeftPanel is where the button is located and the RightPanel is where the JTable is. I want the actionPerformed to update the row of the JTable but I can't figure out how. There is another class that controls the GUI but did not think it was necessary to include. Also, I am aware that I am getting an error at the addRow line, can't seem to alleviate it.

public class LeftPanel extends JPanel {

private static final long serialVersionUID = -2311952438693382407L;
private RightPanel rPanel;
public LeftPanel(){
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);

Swing/AWT/SWT :: Unwanted Echo Of JTextField

Oct 29, 2014

I recently began writing a much larger program than I will show. I have boiled the problem down to this SSCCE.

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JRadioButton;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;
class TextButton extends JRadioButton

[Code] ....

What i wanted was a JRadioButton with no label carrying around a JTextField. When I added a restore configuration feature in the real program, i found that the text destined for the JTextField was being echoed into the JRadioButton.

Perhaps it is obvious but i sure don't see what I am doing wrong. I am using Java 1.7.0 for development if that makes a difference.

JavaFX :: Editable And Saveable Database

Jul 22, 2014

I am rather new to Java and to Javafx, I was able to make my program work to a point. I would like the file that is opened to appear in the editor tab and other files I open to appear in the viewer tab if they are not being edited. From what I have looked up I think that the HTML text editor might be the one for me the only question I have is how do I implement it and the file chooser ( because I think that would work).

import javafx.application.Application;
import static javafx.application.Application.launch;

Swing/AWT/SWT :: JTextField Size Changes With JLabel Text Length

Nov 11, 2014

I want to create 3 JTextFields in a row with all being of equal size.But my first Text field gets so wide than the other two.After adding each component at a time and seeing what causes the problem I realized that if I type a long text for the JLabel that's when this problem occurs.If I reduce the length of the text in the JLabel JTextFields get into the sizes I want. Here's my code

import java.awt.*;
import java.awt.event.*;
import java.lang.Math;
public class Calculator1 extends JFrame {
JTextField value1=new JTextField("0");
JTextField value2=new JTextField("0");

[Code] ....

How can I stop the JTextFields changing size when I change the JLabel label1's text length...

Swing/AWT/SWT :: How To Populate All Items In JTable When Corresponding JTextfield Is Empty

Aug 3, 2014

I am designing a advanced search option in a java project with sqlite in NetBeans. there are 5 different JTextfields and 5 columns, I want to populate JTable with corresponding matching criteria. If a JTextfield is empty then it should select all items of that column.

query i was using is:
String val1=txt_billing2.getText(); //five input fields
String val2=txt_station2.getText();
String val3=txt_invoice2.getText();
String val4=txt_amonth2.getText();
String val5=txt_umonth2.getText();

[code]....

but when i leave a JTextfield empty it shows no data in JTable. only method i know is to use if else conditions but that generates 5!= 120 conditions!!!

Swing/AWT/SWT :: Add JTextField And Additional Output Within ComponentEvent Handlers

Jan 30, 2014

Using the code from the Java Docs (listed below) I am getting behavior that was a bit unexpected. The only changes were to add JTextField and additional output within the ComponentEvent handlers. Run the code and when the frame appears, think of each side as North, South, East (right side) and West (left side) as you are looking at it. This was run using JDK 1.7.0_25.

Run the code.

1 - Click the East edge (right) of the frame and drag to be wider or more narrow. Only the "Resized" is executed for all components which makes sense.

2 - Click the West edge (left) of the frame and drag to be wider or more narrow. This time "Resized" is executed for all components EXCEPT it is "Moved" for JFrame. Why is it "Moved" here for JFrame but not in Step 1?

3 - Click the South edge (bottom) of the frame and drag to be taller or shorter. This time only 2 components are affected. JPanel is "Moved" while JFrame is "Resized".Why isn't both JFrame and JPanel just "Resized"?

4 - Click the North edge (top) of the frame and drag to be taller or shorter. This time only 2 components are affected again but the output is slightly different. JPanel is "Moved" while JFrame is BOTH "Resized" and "Moved".

There just doesn't seem to be consistency here. What are the guidelines or criteria for when these Events are to be executed?

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class ComponentEventDemo extends JPanel
implements ComponentListener,
ItemListener {
