jlist

A struggling Java newbie here - help! I'm trying to: - Get all the selected values from a JList - Create an ArrayList from those values It seems getSelectedValues is deprecated? Until JDK 1.6 (deprecated in 1.7): public Object[] getSelectedValues() New since JDK 1.7: public List<E> getSelectedValuesList() Returns a list of all the selected items, in increasing order based on their indices in the list. As of JDK1.7 it was replaced with public List<E> getSelectedValuesList() . http://docs.oracle.com/javase/7/docs/api/javax/swing/JList.html#getSelectedValuesList%28%29 use getSelectedValuesList

"Is there any way to prevent a JList from selecting the last element when the user clicks below it on the list?" That is the question someone asked here and I have the same problem. That guy found a so-so solution (by overriding processMouseEvent() ) but I want to know if there is a better/more elegant way to do it. [Edit] Ok, more detail. If you have a JList and there is some space unoccupied by any cell/element and you click that space then the last element in the JList got selected. For a real example try this JList Swing Tutorial example , click the white space and see that Rollo got

This question already has an answer here: Disable items in JList 4 answers I was wondering how to modify a JList so that clicking any values would not do anything. I have looked at other questions but none have helped. I solved it by using the following class: class DisabledItemSelectionModel extends DefaultListSelectionModel { @Override public void setSelectionInterval(int index0, int index1) { super.setSelectionInterval(-1, -1); } } I instantiated the class here: console.setSelectionModel(new DisabledItemSelectionModel()); StormeHawke Assuming your objects in your JList are clickable items,

I want to JList a lot of results in a JOptionPane, however, I'm not sure how to add in a scroll function should there be too many results. How would I add a scroll bar to a JOptionPane? Any help would be great. Thanks. GETah Here is an example using a JTextArea embedded in a JScrollPane : JTextArea textArea = new JTextArea("Insert your Text here"); JScrollPane scrollPane = new JScrollPane(textArea); textArea.setLineWrap(true); textArea.setWrapStyleWord(true); scrollPane.setPreferredSize( new Dimension( 500, 500 ) ); JOptionPane.showMessageDialog(null, scrollPane, "dialog test with textarea",

I was wondering if there is a way to retrieve a list of all the elements that have been added to a JList. For example I would like JList to return an array or list of Strings or JLabels from a custom cell renderer. Yes of course. You getElementAt() with a loop. Example: import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.DefaultListModel; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JList; import javax.swing.JScrollPane; import javax.swing.WindowConstants; public class Jlist { JFrame frame; JList

Is there any way to use ListSelectionListener or MouseAdapter to get information about selected value (if value is a String for example), is there any built-in method for that? I only know how to get proper indexes but not the content or content.toString() I'm adding element like this: { DefaultListModel listModel; listModel.addElement(name); } @Edit Thank you for you for help. I solved my problem by doing this (for future generations so they wouldn't need to search as I did): list.addMouseListener(new MouseAdapter(){ @Override public void mouseClicked(MouseEvent e) { System.out.println("Mouse
