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)?
I'm writing a java program in eclipse of a tic-tac-toe game. I have to create it using JTextField's only I'm having trouble where the JTextField will only accept one letter and will only accept X and O is there any particular way to do this I started off with this piece of code
String text=tf1.getText(); if(text.length()>1) { System.out.println("this is not allowed"); tf1.setText("");
But it doesn't work so is there something I'm missing....
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);
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 :
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.
Im writing a program that records the score in a dart game. One component of the program is a stage where players enter their name.This information needs to be displayed in another part of the program. These two components are in two different classes. My problem is I dont know how to get that information from one class to another.
Im using Jtextfield in Jframe to record the information.
I want to have JTextField automatically highlighting the current values for overwriting when the box is selected. Is there a way to do this? It seems like something that might occur in an action listener.
I need to take the value of what's typed in my JTextField, and once the submit button is clicked, I want to add that string to my JComboBox list items.
Depending which RadioButton they selected, I need to put the team in HOME or AWAY teams, and so on and so on, until they continue clicking submit.
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...
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!!!
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 {
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));
I have a swing jFrame set up with a control group which contains 3 radio buttons.
When one is clicked it sends its label to a jtextfield in a different class i have code parsing text by a term
Java Code:
Scanner s = null; try { s = new Scanner(new BufferedReader(new FileReader("/Stage_One.txt"))); s.useDelimiter("*"); String total = (s.next()); Pattern p = Pattern.compile("[]+");
[Code] ....
I just need to know how to access the jframe variables (textfields, panels and such) so i can use their inputs in code to filter a text file.
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 have a supermarket checkout line where i have a list of available products on the left and then a basket on the right with the products in. The products are listed in an array, here is the product class
public class Product { private String name; private double weight; private double price;
[Code] ....
with getters and setters excluded, and the list these are put into
public class productList extends DefaultListModel { public productList (){ super(); } public void addProduct (String name, double weight, double price, int code){ super.addElement(new Product(name, weight, price, code));
i have the price for each product to be displayed in a text field with the following code
addBasketItem = new JButton(); getContentPane().add(addBasketItem); addBasketItem.setText("Add >");
[Code] ....
defaultCheckoutList contains my available items and defaultMainList is the basket, with mainTillPrice being the jtextfield.
This works to get the price however it just replaces each time i make a new entry with the price for the next item, i want a total of the price of all the items i have added, but not sure how.
I enter a value in the text box in one class and want to pass that value to another class in order to compare it and color the cell in a table. In the first class I have
Will I'm tying in my code to set a default number for the JTextField that when the user decide not to put any numbers. Like let say that I want the textfield set to 0 , so then the user do not file it it won't make any problem to the program because its already has a default number.
Note: This is a small part of my code. when I leave it empty it take the 0 as a value, However, when I write in text field it also take the value of a 0 and the finalTotal is also = to 0.what I'm doing wrong.
I am creating a slot machine using eclipse. I am trying to get the "winnings" JTextField to be updated in a way so that when the random images have been selected it adds to the number that is already displayed in the JTextField as opposed to what it is doing at the minute which is just displaying how much was won on that particular spin. I am also struggling to set a code for when noting is won, nothing is added. My code is below.
I currently building a hotel reservation system, and I'm having issues with retrieving and setting other values from a JTextField.
What I'm trying to do is to retrieve the value that was inputted into a textfield, and then setting that value to a string in another class.
In here, I'm trying to retrieve values from the JTextField:
@Override public void actionPerformed(ActionEvent event) { GuestInfo gi = new GuestInfo(); if (event.getSource()==roomView) { roomViewFrame.setVisible(true); roomViewFrame.setSize(1000, 600);
designing a program which allows you to buy stuff from the jframe with 10x items each with different pricing, so once you click the image button the cost of that is displayed in the textfield, ive been trying to set the jtextfield to a decimal point but have not been able to so far,
jTotal.setText(Double.toString(dTotal)); DecimalFormat myFormatter = new DecimalFormat("#####.#"); String output = myFormatter.format(dTotal); a visual aspect of it.
How would I display certain output text if the text entered equaled "text".
So lets say you enter a question into a JTextField. You press a button that submits the text. The output displayed depends on what the question you asked was.
Think about it as "If question = What color is the sky? On submit, display text "Blue". How to implement this.
