jcheckbox

My program contains a label with the caption “Choose a coffee” and four check boxes – Americano, Espresso, Double Espresso and Latte. Note: A JCheckBox array is recommended here) I need to add event handling code to allow the user to purchase one or more items. The bill amount is displayed in a label after the user has made their selections. The prices are Americano €3.75, Espresso €4.00, Double Espresso €4.50 and Latte €3.50. An array is suitable here also. As the user makes a choice a label is displayed showing the bill. I cant figure out how to add the cost when the check box is selected

This question already has an answer here: Tristate Checkboxes in Java 9 answers I want a JCheckbox that has 3 states as shown below: Partially Selected Unselected Full Selected Q1. Can I use the JCheckbox for the above purpose or have to go for some custom swing component? Peter Lang Here is an example for a TristateCheckBox: http://www.javaspecialists.co.za/archive/Issue145.html OscarRyz Oh yes, but you have to create a custom component. Take a look at this article in the Java Specialist and see if it works for you. It needs a bit of work in OSX though. WinXP: I dont know why anyone would

I have a problem in changing the location of the accessory component in a filechooser. I customized a save file dialog by putting a check box in the accessory component of the file chooser. But the position of the check box is not good, it is really ugly. Can I move the accessory component to be underneath the file pane? How to do it? Or if you have other solution to do the same thing, also welcome. Thank you guys. I using following code to add the check box: JFileChooser fc = new JFileChooser(file) JPanel accessory = new JPanel(); JCheckBox isOpenBox = new JCheckBox("Open file after saving");

I am trying to create several similar visual styles for my programs, each with a different color theme. To do this, I have implemented the use of icons to represent the different states of JCheckBox s and JRadioButton s. Instead of making one full set of icons for every possible color, is there any way I can just take one set and change the hue/saturation/luminosity/alpha of the image before displaying it? There is a way, but you'll have to make use of some BufferedImage transformations. Once you create them, cache them or save them off to be easily reused later. Essentially, you want to start

Both ActionListener and ItemListener are used to fire an event with JCheckBox? So, what's the difference between them and in which case one of them is preferred to the other? NiranjanBhat Both ItemListener as well as ActionListener , in case of JCheckBox have the same behaviour. However, major difference is ItemListener can be triggered by calling the setSelected(true) on the checkbox. As a coding practice do not register both ItemListener as well as ActionListener with the JCheckBox , in order to avoid inconsistency. The difference is that ActionEvent is fired when the action is performed on

Probably a noob question, but im new to java. I have a need for a checkbox list which I found is not supported in swing, but I found this custom control here http://www.devx.com/tips/Tip/5342 So I created a class file named CheckBoxList, and copied the code from the link into it: import javax.swing.*; import javax.swing.border.*; import java.awt.*; import java.awt.event.*; public class CheckBoxList extends JList { protected static Border noFocusBorder = new EmptyBorder(1, 1, 1, 1); public CheckBoxList() { setCellRenderer(new CellRenderer()); addMouseListener(new MouseAdapter() { public void

I am using DefaultTableModel as follows: DefaultTableModel model = new DefaultTableModel (COLUMNS, 0 ) { @Override public boolean isCellEditable(int row, int column) { return (getColumnName(column).equals("Selected")); } public Class getColumnClass(int columnIndex) { if(getColumnName(columnIndex).equals("Selected")) return Boolean.class; return super.getColumnClass(columnIndex); } }; Now I want to make only one checkbox selectable in the column "Selected". How can this be done. I have tried following method also but its not working. public void fireTableCellUpdated(int row,int column) { if

I'm very new to programming, and I can't add JCheckbox to the JList . There is no error but nothing is displayed. JFrame f=new JFrame(); String[] labels={"a","b","c","d","e"}; JCheckBox[] ch=new JCheckBox[labels.length]; JList list=new JList(); for (int i = 0; i < labels.length; i++) { ch[i]=new JCheckBox("CheckBox"+i); list.add(ch[i]); } JScrollPane pane=new JScrollPane(list); f.add(pane); f.setVisible(true); trashgod A JList renderer can draw a checkbox, but JList does not support a cell editor. Instead, consider a one-column JTable . The default renderer & editor for a column of type

I made few checkboxes using swing in Java. I want to write a superscript text for the checkboxes but I'm not sure how. The code currently looks like this. JCheckBox hCheckBox = new JCheckBox("[M + H]+"); I want to have "+" sign inside the JCheckBox parameter superscripted. What's an easy way to do this? Thank you in advance. Java buttons support html in their text. You need to format the string a little differently though. Try this: JCheckBox hCheckBox = new JCheckBox("<html>[M + H]⁺</html>"); package infonode; /** * * @author Deepak */ import java.awt.*; import java.awt.event.*;
