JComboBox editing
Hi all! I have a JCombobox in a JTable component. In my combobox, I have 3 items, the first two are fixed items except the third item which has a String value of "Enter Nth element". When the user clicks on
the third element, the combobox should be editable and it should clear the current value of "Enter Nth element" to blank and it should have focus for the user to be ready to enter numbers. My problem is that when the user selects the 3rd element, it sets the value to blank but you have to go back and double click on the cell again to be able to edit it. Please help I've tried everything....
I think you're going to have to take more explicit control over the celleditor functionality of JTable. In other words, you'll have to create your own cell editor for that particular column of the JTable. Obiviously, the JTable assumes that editing is complete when the user selects the third element of the combobox, and therefore replaces the editor with the cell renderer, which causes the user to reselect the cell for editing again. I'm sorry that I don't have actual code to present to you; however, I would approach solving the problem from that angle. Good luck!

hi all ,
I have problem with JComboBox
like this :
JComboBox comTech = new JComboBox();
comTech.addItem(" ");
comTech.addItem("one");
comTech.addItem("two");
the problem is I want first( comTech.addItem(" ");) item is Editable remaing are uneditable
I am not getting any solution if anyone knows please send the solution
thanksYou missunderstand the use of JComboBox. A JComboBox is used to allow the user to selection from a list of items.
An uneditable combox allows the user to select an item from the list.
An editable combo box allows the user to select an item from the list or to enter there own value. It does not allow you to change the value of the entries in the list.
See this section from the Swing tutorial on "How to Use Combo Boxes":

Distiinguish JComboBox editing event from selection event
In an editable JComboBox I need the event that the selection via popup has changed and not due to finish the editing of an entry.
For test I added listener for ItemStateChanged and ActionEvent. The sequence is
a) for selection change (from 'bbb' to 'aaa')
itemStateChanged: java.awt.event.ItemEvent[ITEM_STATE_CHANGED,item=bbb,stateChange=DESELECTED] on coFilter
itemStateChanged: java.awt.event.ItemEvent[ITEM_STATE_CHANGED,item=aaa,stateChange=SELECTED] on coFilter
actionPerformed : java.awt.event.ActionEvent[ACTION_PERFORMED,cmd=comboBoxChanged,when=1129716754377,modifiers=Button1] on coFilter
b) after editing the current entry has been finished (from 'aaa' to 'aaa123')
itemStateChanged: java.awt.event.ItemEvent[ITEM_STATE_CHANGED,item=aaa,stateChange=DESELECTED] on coFilter
itemStateChanged: java.awt.event.ItemEvent[ITEM_STATE_CHANGED,item=aaa123,stateChange=SELECTED] on coFilter
actionPerformed : java.awt.event.ActionEvent[ACTION_PERFORMED,cmd=comboBoxChanged,when=1129716711382,modifiers=] on coFilter
actionPerformed : java.awt.event.ActionEvent[ACTION_PERFORMED,cmd=comboBoxEdited,when=1129716711382,modifiers=] on coFilter
Is there a simple way to catch the first situation only and not reacting for the second sequence?
Thanks in advance

Returning index of selected comp... jComboBox that is editing a jTable cell
so, i'm using an array to populate the choices of a combobox
public String[] progCodes = new String[]{"Standard","Restricted","Combined","Special"};which i'm using to edit a cell in a jtable
baseCatTable.getColumnModel().getColumn(4).setCellEditor(new DefaultCellEditor(new JComboBox(progCodes)));and when i get the value
System.out.println(baseCatTable.getValueAt(0, 4))i'd like to return the index of the selected item in the combo box instead of the text:
Standard
any suggestions?

KeyListener is not working with editable JComboBox??!!!
When I make the JComboBox editable property to true, the keylistener of the jcombobox is not working why?
How can I solve this problem?
Please help
HaroonWhen editable, focus is placed on the editor component of the combo box. So you need to add the KeyListener to the editior component.
comboBox.getEditor().getEditerComponent().addKeyListener(...); -
Why ComboBox.disabledForeground not take effect when JComboBox is editable
Hi, there:
I use UIManager.getDefaults().put("ComboBox.disabledForeground", Color.GRAY ) to define the fore ground color when my JComboBox is disabled. However, just noticed that if I set JComboBox Editable to be true, then, the application seems using the default disabledForeground color instead of the one I defined (ex. gray).
For example:
UIManager.getDefaults().put("ComboBox.disabledForeground", Color.gray );
comboBox.setSelectedItem("bbbbbb");
//comboBox.setEditable(true);
comboBox.setEnabled(false);The above code works fine and set foregound color as gray. However, if I added the line: comboBox.setEditable(true); The application just uses default foreground color (light blue in 1.5).
Does any one know why?
Highly appreciated if any comments or hints.
Thanks a lot in advance.

How to filtering jcombobox iterm
Hi
If there is any possible to filtering JComboBox Item based on entering my character basis in jcomboBox editing area .
( i.e ) Suppose I want enter A character in jcombobox Field , it filtering all item start with 'A' or highlights the A character from combobox Item like that , if it is possible give me a solution to how to solve it.This just might be a record.

How to make JComboBox display an item not in list?
hi,
i'd like a gui component which is basically a jcombobox that presents a list A,B,C,D.
The combobox is paired with another gui component which allows choosing sets of items. A etc.. represent preselected sets of items, so the user can click on A and a particular set would be selected.
My problem is what to have the JComboBox do when the user selects a set of items that is not in the preselected defaults list. It would be nice to have the JComboBox just say "Other" at the top or something, but I can't figure out a way of doing this without putting the String "Other" in the list of items..
does anyone have any idea of how to approach this? (I looked at making the JComboBox editable but this seems a little complicated?)
thanks,
asjfYour best option and cleanest design is to have a
dummy data item in your list for "none of the above". thanks for the reply - this is what I'm doing at the moment. The problem is that I'm expecting testers to legitimately complain that selecting "None of the above" doesn't do anything, and doesn't really make sense ( it could make a random selection :o) )
i think i agree that adding functionality to do this "properly" is likely to be more work/pain than its worth..
Only an editable combobox can display something not in the list.this might help - if I could block mouse clicks to the editable area, and write to it programmatically but think this is probably quite difficult (?)

Hello,
Can ynay one tell me how exactly this JComboBox behaves regarding regarding the mouse listeners and key listeners.
I have a JComboBox element the ActionListener for this works very well but I made the JComboBox editable and the I add KeyListener to the JComboBox element to implement a feature to activate a button when we type something in the JComboBox
Now my second question is can't I implement mouseListeners to this JComboBox field.
If any one knows can you please help me by posting a small example on how to implemet KeyListeners and MouseListeners on JComboBox
Best Regards,
SreedharHello..
That really works you have done a great help to me. But I have one doubt it works well for default MouseListeners, but when I introduceda MouseAdapater and try to implement that it does'nt works. Do you know why this is so.
Any now I'm using a default MouseListener but for a userdefined MouseAdapter it is not working.
Thank you once again.
Best Regards,
Sreedhar -

I installed JDeveloper 11.1.1.3.0 and cracked the nut. The LOV driven ComboBoxes in JTables will remain empty after migrating to the new version, but it seems to be merely a bug in the migration. What you need to do in order to get the ComboBoxes working is the following:
I found out that in your PageDefs you need to add two attributes to the <combobox> definitions:
ControlClass="javax.swing.JComboBox" Editable="false"
This makes the ComboBoxes look like in previous releases. If you skip the "Editable" attribute, the user can type in values, which does not really work in LOVs but in static lists.
Unfortunately I experienced another bug in the 11.1.1.3.0 release concerning LOVs: When defining the LOV in the ViewDef, JDeveloper wouldn't let you specify any additional columns to be displayed in the LOV ("Display Attributes"). -> The workaround is much easier than I first thought: Just resize the dialog a little bigger and the selection fields that I first missed appear!
In the moment it looks to me like I could continue development with JDeveloper 11.1.1.3.0.

There are a couple things which I want my popup menu to do.
1. When the user opens the popup and then immediately proceeds to click a button (like a JButton or a tab of a JTabbedPane), I want that button to be able to click right away. Right now, the first click just causes the popup to disappear, but does not click the button.
2. (Optional) I want the popup to disappear when the mouse is not hovering over it or the button that spawned it.
See the below demo for the optimal behavior. Click on the File/Edit/Insert/Format/View/Tools menubar to spawn a popup.
http://demos.telerik.com/aspnet-ajax/menu/examples/default/defaultcs.aspx
How do I achieve this?
Thanks!no answer, sorry - just a comment (surprise seems to be THE feeling today :) whether or not a click on any component has any effect depends on both the type of component and LAF. Below is an example (in terms of SwingX visual example support, too lazy to rewrite ;) which demonstrates a couple of harhars - open the popup on the panel then
- click the button does not trigger its action
- click the checkBox toggles its the selection in Metal, does nothing in Windows
- click the not-editable combo opens the combos popup always
- click the text field of the editable combo doesn't even close the popup
Enjoy!

Hi,
I have a Frame with multiple editable JComboBoxes, but I am at a loss as to how to sort them out in the focusGained() method.
It is easy when they are not editable, because the FocusEvent getSource() Method returns the box that fired the event. That lets me read an instance variable that is set differently for each box.
But with editable boxes, the FocusEvent is not fired by the box. It is fired by a Component object returned by getEditor().getEditorComponent(). So far I cannot find a way to query that object to find the box it it tied to. (I hope this isn't going to be painfully embarassing.).
Anyway, the code below produces a frame with four vertical components: a JTextField (textField), a NON-Editable JComboBox (comboBox1) and two Editable JComboBoxes (comboBox2 & comboBox3).
This is the command screen produced by :
- Running the class
- Then tabbing through all the components to return to the text field.
I am not sure why, but it gives the last component added the foucus on startup.Focus Gained - Begin: *****
This is the comboBox that Is Not Editable
Focus Gained - End: *******
Focus Gained - Begin: *****
This Is The TextField
Focus Gained - End: *******
Focus Gained - Begin: *****
Class: class javax.swing.plaf.metal.MetalComboBoxEditor$1
Name: javax.swing.plaf.metal.MetalComboBoxEditor$1
Focus Gained - End: *******
Focus Gained - Begin: *****
Class: class javax.swing.plaf.metal.MetalComboBoxEditor$1
Name: javax.swing.plaf.metal.MetalComboBoxEditor$1
Focus Gained - End: *******
Focus Gained - Begin: *****
This is the comboBox that Is Not Editable
Focus Gained - End: *******
Focus Gained - Begin: *****
This Is The TextField
Focus Gained - End: *******As you can see, the FocusEvent source for both editable boxes is a MetalComboBoxEditor. Both have identical names.
Can anyone help me get from there back to the actual combo box so I can read the instance variable to see which one fired the event?

public void focusLost (FocusEvent fle) { }
public void changedUpdate (DocumentEvent de) { }
public void insertUpdate (DocumentEvent de) { }
public void removeUpdate (DocumentEvent de) { }
public void itemStateChanged (ItemEvent ie) { }
}I added the following in your focusGained() method and it seemed to work:
Component c = ((Component)fge.getSource ()).getParent();
if (c instanceof JComboBox)
JComboBox cb = (JComboBox)c;
System.out.println("Selected: " + cb.getSelectedItem());

Problem using an editable JComboBox as JTable cell editor
Hi,
i have a problem using an editable JComboBox as cell editor in a JTable.
When i edit the combo and then I press the TAB or ENTER key then all works fine and the value in the TableModel is updated with the edited one, but if i leave the cell with the mouse then the value is not passed to the TableModel. Why ? Is there a way to solve this problem ?

Editable JCombobox cell editor length limit
Hi All,
I have an editable JCombobox as a celleditor to one of the column in JTable, How do I limit the characters in the cell editor?
ThanksA JComboBox uses a JTextField as it's cell editor. You should read up on how you would do this for a normal JTextField by using a custom Document:
http://java.sun.com/docs/books/tutorial/uiswing/components/generaltext.html
Here's an example using JComboBox. I haven't tried it in a JTable but I assume it should work.
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;
import javax.swing.plaf.basic.*;
public class ComboBoxNumericEditor extends BasicComboBoxEditor
public ComboBoxNumericEditor(JComboBox box)
editor.setDocument( new NumericListDocument(box.getModel()) );
public static void main(String[] args)
String[] items = { "one", "two", "three", "four" };
JComboBox list = new JComboBox( items );
list.setEditable( true );
list.setEditor( new ComboBoxNumericEditor( list ) );
JFrame frame = new JFrame();
frame.getContentPane().add( list );
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frame.pack();
frame.setLocationRelativeTo( null );
frame.setVisible( true );
class NumericListDocument extends PlainDocument
ListModel model;
public NumericListDocument(ListModel model)
this.model = model;
public void insertString(int offset, String text, AttributeSet a)
throws BadLocationException
// Accept all entries in the ListModel
for (int i = 0; i < model.getSize(); i++)
Object item = model.getElementAt(i);
if (text.equals( item.toString() ))
super.insertString(offset, text, a);
return;
// Build the new text string assuming the insert is successfull
String oldText = getText(0, getLength());
String newText =
oldText.substring(0, offset) + text + oldText.substring(offset);
// Edit the length of the new string
if (newText.length() > 2)
Toolkit.getDefaultToolkit().beep();
return;
// Only numeric characters are allowed in the new string
// (appending the "0" will allow an empty string to be valid)
try
Integer.parseInt(newText + "0");
super.insertString(offset, text, a);
catch (NumberFormatException e)
Toolkit.getDefaultToolkit().beep();
}
