View RepliesI am trying to populate a JTable using Several JTextFeild a JComboBox and a JLabel.
The textfields are originalPrice and itemName
JComboBox is departmentComboBox
label is salePriceLable.
When hitting the button i need the program to calculate the price after discount and add the item name, department, original price, and discounted price to a table. I have the calculation down, but am lost on populating the table.I used NetBeans 8.2
/*
* Program: JavaRetailCalculator
* Purpose: To calculate the ammount of a discount and display results in a Table
*/
import java.awt.*;
import javax.swing.*;
public class CalculatorFrame extends javax.swing.JFrame {
/**

I have a ComboBox I'm using for a cellEditor. The list of items in the comboBox might have colors behind them, which I've managed to render. What I haven't figured out is a good way to keep the color in the cell after the item is selected.I don't' want to have a persistent comboBox in the cell, i only want to see it when editing that cell.
public TableCellEditor getCellEditor(int row, int col)
{
if (row==theRow && col==theCol)
{
JComboBox<?> combo = new JComboBox<Object>(getPickListEntries());
combo.setRenderer(new PickListRenderer(combo));
combo.setBorder(BorderFactory.createEmptyBorder());
}

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!!!
I am having an issue with my swing gui. I dynamically create tabs with information (textfields, checkboxes, combo boxes) and when I select the checkbox it disables or enables a textfield. Now when I select the checkbox it seems to resize everything, specifically my textfields from say 9 columns to probably one. I"m a little unsure why it is doing this but I have a feeling it may be an inheritence issue.
My code is below for my generation of the tabs and of the rest of the information on the gui. The gui is an inner rid layout with a top and bottom pane that are both gridbaglayouts and an outter pane as well. I am thinking I am missing something in the grid layout setup that is causing this.
private void initComponents() {
jTabbedPane1 = new javax.swing.JTabbedPane();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
getContentPane().setLayout(new java.awt.GridLayout(1, 0));
pack();

I'm learning Java using BlueJ, I have made a class that has a HashMap of (String, String) that contains an the make of a car and the model.
I want a method to return a collection of all the keys that satisfy a condition, like if someone wants to find what make a certain model is. I know it requires a loop, just not too sure how to write the loop to satisfy the condition.
I have a selection listener attached to a TreeView as shown below
treeView.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<TreeItem<Pair<VideoSourceType, String>>>() {
@Override
public void changed(ObservableValue<? extends TreeItem<Pair<VideoSourceType, String>>> observable, final TreeItem<Pair<VideoSourceType, String>> oldValue, final TreeItem<Pair<VideoSourceType, String>> newValue) {
// do something
treeView.getSelectionModel().clearSelection();
}
};
What I want to do is to "do something" and then clear the selection so that it can be selected again. However, I cannot re-select the same item from the TreeView until I first select a different item.
I want to render a specific region of an image in LWJGL,
View Replies View RelatedWhat it's supposed to do: This code is supposed to see if the clicked card is selected. If it's not, select it and show the player where it can move / attack. If it is selected, then find out what card the player clicked on. If he clicked on the card that was already selected, deselect it. If he clicks on a friendly card (same playerID), then select that card. If he clicks on an enemy card (different playerID), attack that card. If he clicks on a tile, move it to that tile.
The problem: However, line 24-58 give me a bit of a problem. Right now, it works fine BECAUSE lines 46-58 are commented (which also means the unit can't move). If I uncomment those lines, the unit becomes able to move, however, lines 34-46 cease working...
Java Code:
@Override
public void mouseClicked(MouseEvent e) {
mainloop: for (int i = 0; i < Main.cards.size(); i++) {
Card c = (Card) Main.cards.get(i);
if (Card.cardSelected == null) {// Contains / Is not selected
if (c.contains(e.getX(), e.getY())) {
Tile.reset();
Card.reset();
Card.cardSelected = c;

but it didn't appear. Still the first entered value appears when the program is run.should I put this line on some other place, or is there any other code, other way to add this text as first value in the combobox?
I'm working on assignment for a class where I'm creating a home utility auditor. Basically the user has to pick from a list of appliances and then input various fields to calculate a total cost. When the user chooses "washer" from the list of appliances, they must enter in values for 2 separate fields, and will then click calculate to get total cost. I've been trying to implement this through an if, else statement, but it's not wanting to calculate a total cost and I'm running into errors. I've put the code below.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// The calculate button will multiply the 3 fields that the user inputs:
//cost*Kw used*hours used=total cost of operation
float num1,num2, num3, result;
//now, parse the text to a type float
num1= Float.parseFloat (costField.getText ());

Enhance the form you created in homework 3 to add a JCombobox to select the user’s State of residence, and a group of JRadio buttons to indicate the user's gender. Once the user clicks on the JButton (created in homework 3) the application will display all of the user’s information in the JTextearea in a format similar to the following:
Name:
Age:
Gender:
Age Group:
State of Residence:
This is my code so far. I am having trouble with trying to select a state from my comboBox. My box prints out on the screen fine, but it will not allow me to select a state and print out a state. I was able to get the event listener to work for my radio buttons ok. But I am stuck on the comboBox.

Question: How can I add an Item to a combobox when I click a button?
View Replies View RelatedI understand how vectors work I'm currently using one to store my id's from my txt file but how do you put them in a defaultComboBoxModel?
DefaultComboBoxModel defaultComboBoxModel = new DefaultComboBoxModel();
//declare a vector object that will hold a string (only thing that works with comboboxmodel
Vector<String> myVector=new Vector<String>();
//try statement
try{
FileReader fr = new FileReader(file);

Any example of how a vector is used with a defaultComboBoxModel so I can then use that to populate my JComboBox?

I have a combo box inside a table cell for each row. I have defined a value change listener for each combobox. Whenever the combo box value is changed, the selected item is placed inside a MAPVOBean. The problem i am facing is when the user scrolls Up and down the tableview , the change listener is fired even without clicking on it the explicitly, and this changes the my value in my data structure. How to handle this. The source code is attached.
My Model:
Person class
Has first name, last name and MAPVOBean.
Address is stored in a MAPVOBean. It has a map and key is house number and the value is the state where the house is. It is assumed that the person can have one house in each state.
Columns in table view:
Column 1: First Name
Column 2: Last name
Column 3: State combo box. This shows the state in which the person owns a house.

I am developing a form with ComboBox as a subject (the user can choose one from the list , or type one) and TextArea where the user can write his notes (attached a picture). The user using a virtual keyboard (touch) to enter any characters.
I am using the append method to append the next Char to the TextInputControl class (both Combo and TextArea Inherit from it). When I try to deletePreviousChar() in the TextArea it works, but in ComboBox it fails
I put some System.out.println() to see what is the problem and it seems that with the ComboBox the class is loosing the Caret position after every action
Here is my code: (Look it also as a attached picture)
public void changed(ObservableValue<? extends String> observable,
String oldVal, String newVal) {
if (newVal != null) {
if (lastNodeInFocus instanceof TextArea) {
switch (newVal) {
[Code] ....
Here is the Debug results: CB = Combo TA = TextArea B=Before A=After , the numbers are the caret position (also attached as a picture )
CB - append B 0
CB - append A :1
CB - append B 0
CB - append A :2
CB - append B 0
