jlist

Part of my code ArrayList<Item> i = g.getItems(); Vector itemsVector = new Vector(i); JList items = new JList(iemsVector); Later in the code I create new object which I want to add to JList. How can I do that? Populate the JList with a DefaultListModel, not a vector, and have the model visible in the class. Then simply call addElement on the list model to add items to it. You may add it ( new object ) to the itemsVector (Vector). After adding an item into Vector object invoke the items.setListData(itemsVector); method. Well you can not use directly that Array but use this this will might help

I was googling for a solution to retrieve data back from a JList component, but didn't find any.So, is there a method of Jlist that return its items? I don't want just a selected one. I want the whole list. The reason is I have this method that updates all the components of a dialogbox base on the selected value of a list box. I want to update that list box from the same method. So to do that, the method should not update the list box whenever it gets called. It should compare the values in the list box with the most recent data that I store in one class.(goes into infinite loop otherwise)

An application i am working on requires the use of a JList where each ListItem is a Label followed by a Button. What i did is i created a Class having a String member for the Text field and added the Class Objects to the Jlist. Now for the Button,i implemented a Custom List Cell Renderer which is as : public renderer() { text=new JLabel(); button=new JButton("Track"); button.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { // TODO Auto-generated method stub System.out.println("Hey"); } }); } public Component getListCellRendererComponent(JList

I have a JTextField and a JList in my program. The JList contains the user's contacts. I'd like to filter the JList based on the text on the JTextField. For example, if I type in "Mike" it will only show contacts including "Mike". When the user clears the JTextField it would reset the filter. I know I could do this manually by having two arrays. One for the original contacts and one for the filtered ones. When the user changes the value of the JTextField I would go trought the original list, update the temporary list and update the JList. I just wonder if there is some built in feature to
