jlist

I have a list called reminderList . When the mouse clicks on an item in the list and the mouse exits the list, i want a timer to start. When the mouse enters the list, i want that timer to stop, if it is still running. When the mouse exits the list again, i want that same timer to restart. public void waitReminderList(int status) { Timer timer = new Timer(10000, new ActionListener() { public void actionPerformed(ActionEvent evt) { reminderList.clearSelection(); dismissReminder.setEnabled(false); } }); if (status == 0) { if (!reminderList.isSelectionEmpty()) { timer.setRepeats(false); timer

I'm trying to change the background color of a JList cell when it is being hovered over, but I'm not sure how to do it. Here is what I currently have: package cats.youtube.gui; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Component; import java.awt.Rectangle; import java.awt.event.MouseEvent; import java.util.LinkedList; import javax.swing.AbstractListModel; import javax.swing.DefaultListCellRenderer; import javax.swing.JList; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.ListSelectionModel; import javax

Question: Is there an easy way to sort jList using Up/Down Buttons on jFrame? My JList stores path's of image files and displays string with name of the file.

Button2 is button "up". private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) { int indexOfSelected = jList1.getSelectedIndex(); File selectedFile = (File) jList1.getSelectedValue(); indexOfSelected = indexOfSelected - 1; jList1.setSelectedIndex(indexOfSelected ); jList1

I need to create a Java Swing JList with three Components. Each JList row should have one JCheckBox, one ImageIcon and one JLabel. The problem is that JLabel could have only two elements.

Hi I am having trouble with toggling a check box that is in a JList, I wish for when an item is clicked to have the check box tick, and if it is ticked again i want it to toggle to unticked. I want to have it possible to have multiple items to be ticked or unticked without the use of the ctrl or shift keys. public class CustCellRenderer extends JCheckBox implements ListCellRenderer { boolean selected = false; void CustCellRenderer() { setOpaque(true); setIconTextGap(12); } // allows a custom list cell rendering which will enable me to display an icon as well as filename @Override public

I have a Ingredient class public class Ingredient { String NameP; List ListS; String Desc; List ListT; ... multiple instances of this class are stored in a Objects list. I have also a javax.swing.JList ListIng; With it's model set to ListIngModel = new DefaultListModel(); The idea is to use the Jlist to display the field "NameP" of all objects, select one of them to be further inspected and then grab the selected object: Ingredient Selected = ListIngModel.get(ListIng.getSelectedIndex()) I can load the objects in the list model, but then the JList displays the address of those.
