I'm trying to hide (not remove) some items from a JList Java, but I can't find the way.
The process I'm trying to realize is a list with JCheckbox and a search form (textfield). When the user fire some text I filter the list, but I need to keep the state of the checkbox, so I can't remove the item, but only hide or show it.
Thanks for the help.
When the user fire some text I filter the list,
JList does not support filtering.
You can use a single column JTable. JTable does support filtering.
Read the section from the Swing tutorial on Sorting and Filtering for more information and working examples.

Instead of using a JList you could use a single column JTable. A JTable supports the ability to filter the rows of data in the table.
Read the section from the Swing tutorial on Sorting and Filtering for a working example to get you started.
You can even make the JTable look more like a JList by following these suggestions: How to create a JTable which appears as JList?
I'm developing a JAVA swing application, developed using hibernate and mysql as a database.
I'm trying to bind data from a JList to appear on a JTable, when one of items in the list is clicked. For example i have different user types in my application, Supervisor, Manager, Administrator and others.
Each of the user type has users register under them. I want the application to show certain users when a certain item is clicked on the JList. Like when I click on the supervisor item then all registered supervisors must appear on the JTable. Don't know if I'm making sense, but you all allowed to reply and I will try to make you understand better. Thanks.
Like when I click on the supervisor item then all registered supervisors must appear on the JTable.
One way is to populate the table with all the data and then filter the table when you select an item from the JList. Read the section from the Swing tutorial on Sorting and Filtering.
Otherwise you would need to dynamically query you database every time a JList item is selected.
In either case you will need to add a ListSelectionListener to your JList to invoke your processing. Read the section from the Swing tutorial on How to Use Lists for an example.
I am trying to filter a list that is placed into a listview through the use of 2 drop down boxes.
The first dropdown box is titled price and the second is owner.
I want to be able to select a value in one or more of these drop down boxes and then have the List view re-render with the filtered results.
The trouble is I do not know how to begin this task, would someone be so kind as to enlighten me :D
Thanks in advance!
Your best starting point is probably this example: (Source code also available on this page, ChoicePage.java is the name)
First of all, you have to use a dynamic model in your ListView that generates the list of items depending on what you had selected in the dropdown boxes.
Then the basic idea is that you add an AjaxFormComponentUpdatingBehavior to the components that control the updates (your two dropdown boxes in your case), and in the onUpdate() method of this behaviour you should add the component you want to update to that AjaxRequestTarget passed.
I am trying to get a JCheckBox to display on a line that is in the multiple select JList and still perform its functionality.
Right now if I add the JCheckBox as an element it just prints its toString format.
Help/ideas?
If you haven't already done so, you'll need to write a custom ListCellRenderer, as discussed in Writing a Custom Cell Renderer.
Addendum: Because you'll also need an editor to handle the checkbox state, you may find it easier to use a one column JTable, as discussed in How to Use Tables. Note that a data column having the type Boolean will be automatically rendered with a check box.
I'm trying to use a JDialog box that has a search text field that as text is entered, it shortens a list to those that match. On this list I would like to display each line with a checkbox that can be selected. I might also want the ability for it to function like a select all list where Ctrl + Click on the line would select the item and check its box. How do I get this done?
Jlist is exactly what you're looking for. You can use a list of checkboxes and ctrl-click them.
I would use a JTable with two columns. The first column can be your check box and the second column could be the text.
