Combobox focuslistener
Does the combobox Component not fire focus lost and focus gained events?
is there a workaround?
Oopss... nevermind.
Got it working. for someone else, if you have a editable combobox then it does fire focus events.
pnlOrd.getCmbBx().getEditor().getEditorComponent().addFocusListener( listener1 );

Losing focus on editable combobox
Hi everyone!
I have created a combobox and setEditable is set to true but it does not react to the focus lost method.But when the setEditable is set to false then the focus lost method is executed. According to the following Sun Developer sites(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6433257,
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4628933) this is some kind of bug.
Is there no way that I can have an editable combobox that reacts to the focus lost method I mean that loses focus?When you have an editable combo box the editor has focus, not the combox box. So I guess you would need to add the FocusListener to the editor itself and not the combo box directly.

Have anyone ever faced all these problems togather?
Scenarion:
I have a View(According to the MVC structure) that extends a JFrame. In this view I have a JPanel that has comboBoxes and JTextField. These components hold different kind of data types. JTextField holds(int, long, String etc). The comboBoxes holds(true or false). How it works? Data comes from mainframe. If boolean value is received it creates the ComboBox else it creates JTextField. User can type and change data. I have added the focusListener to the JTextField. In the focusLost I do some validation. In focusGained I do nothing. I haven't added any listener to the comboBox. After doing the validation the value get stored to a temporary object. Once the user clicks the save button the code iterate through the object and add the updated values to the list and save that list.
Problems I am facing:
1. When the user keeps the field blank or types invalidData it throws error messages(This is ok). Problem is if the user do the mistakes I mentioned and click the frame the error messages don't pop up.
2. The comboBox has two items true and false. For saving I need to know did the user selected "True" or "False". How can I do that?
3. As I have FocusListener it listenes to the focusEvents. What can I do so it will listen to both focusEvent and keyEvent?
Please responsd as soon as you can.
Thanks,

How to getFocus in a ComboBox without choosing the inside data?
How to getFocus in a ComboBox without choosing the inside data? Once I clicked on the ComboBox, I couldnt get the focus unless I choose the data inside. Although I had tried with many different types listeners, but still couldnt get it. Could anyone help me???
It is easier to work with the JComboBox in 1.4 for what you want to do.
But try this and see if it works for you. I added a FocusListener to all the other components on the panel, and had them close the combo box popup list. Now, if another component previously had the focus, it would take 2 clicks to have the combo box's list pop up. It's quite round-about, but it seems to work.
I also printed a message on the console.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.event.*;
public class ComboBoxPopupTest
public static void main( String [] args )
final JComboBox comboBox = new JComboBox( new Object [] { "one", "two",
"three", "four" } );
JButton button = new JButton( "huh" );
JButton button2 = new JButton( "Yo, baby!" );
final JPanel panel = new JPanel();
final Runnable hidePopup =
new Runnable()
public void run()
// This method is deprecated in 1.4.
// But you won't need it in 1.4 anyway...
Component comp = SwingUtilities.findFocusOwner(panel);
if ( comp != null )
if ( comp.getClass().toString().indexOf("ComboBox") > -1 )
comboBox.setPopupVisible( false );
System.out.println( "helloooo comobox" );
}; // end the Runnable
FocusListener focusListener = new FocusAdapter() {
public void focusLost( FocusEvent evt )
SwingUtilities.invokeLater( hidePopup );
// In Java 1.4, just add a focus listener to the combo box
// instead of adding it to all the other components.
button.addFocusListener( focusListener );
button2.addFocusListener( focusListener );
panel.add( comboBox );
panel.add( button );
panel.add( button2 );
JFrame frame = new JFrame( "Hello" );
frame.getContentPane().add( panel, BorderLayout.CENTER );
frame.setSize( 400, 300 );
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frame.setVisible( true );
}Tell me if that works for you. -
Event of show and hide popup of Combobox
Hi,
The following feature is observed:
I click on a combobox on a panel and the popup is displayed. I click on the panel (blank space, not another component on the panel), the popup of Combobox is hidden. However, I cannot find a listener for the combobox to listen to this event. I've tried ActionListener, FocusListener and some other listeners. I've also tried to add listeners to the components in the combobox.
Component[] c = myCombo.getComponents();
for (int i = 0; i < c.length; i++)
c.addSomeListener(someListener);
But it still doesn't work. Does anybody know what event I should listen to? (Not add listener to the panel, only to the combobox)
Thanks a lot.Up to Java 1.4 there is no event that you can listen to.
In 1.4 you JComboBox has this method:
public void addPopupMenuListener(PopupMenuListener l)
If you can, I really recommend updating to 1.4 (just out in Beta2). There are a lot of small, but overall very important improvements to Swing.

Use ComboBox TableCellEditor - values are not saved to the table model
Hi,
I got a combobox cell editor that uses to edit one of the columns.
And i got an ok button that uses to collect the data from the table and save it to the db.
In case i started editing of a cell and the editor is still displayed- if i will click on the button the data that will be colected from the table model will not contained the updated value in the cell editor.
In this case the user think his changes were saved but the last updated field is not updated.
Is this a bug i got in the cell editor or this is the normal behaviour?
Can it be fixed? (So that if the cell is in the middle of editing the value that will be saved is the last value that was selected).

Getting data in a combobox from database
I have done database connectivity in flex using .net. Now I am getting data in flex in a data grid. Everuthing is working fine if I take data in a data grid.
My problem is that if I try to take that data in any other control, other than data grid, it shows up no data, it only shows "object[object].
for ex:
if I am getting 3 rows from databse and I try to get those in a combo box, den I am getting 3 items in combo box like this:
object[object]
object[object]
object[object]
instead of actual data.
I am stuck in this problem for last 3 days. I have tried lot of things but nuthing is working. Plz anyone help me out soon. Its really urgent.
I am working on a live project and not able to proceed because of this problem.Hi Bhavika,
You need to tell your combobox which value should be displayed in the ComboBox...for display...
You are getting 3 rows from database which are objects since you haven't told your combobox which value to be displayed it is displaying as [Object,Object]...
So you need to tell your ComboBox which values to be displayed ..and you can do this by assigning the labelField property of the ComboBox..
Say in your object you have three properties say..data, value, name...etc;;
Then if you want display name as your ComboBox display label then simply write ....labelField="name" in your ComboBox ...
Thanks,

Problem setting Index value on ComboBox
I am running into a problem with setting the index on a
dropdown box. I will try to give as much detail as possible. From
what I can tell, it should be working and does, but only for one
item. If anyone can suggest a different group to post to, let me
know. I can not find a solution anywhere.
I have the following code to show a combobox. The data is
derived from a XML config file. The combobox itself works fine and
does in fact show all of the data from the XML config file.
<mx:HBox>
<mx:Label text="Status" width="55"/>
<mx:ComboBox id="uxstatus" dataProvider="{_xmlVulnStatus}"
labelField="status"/>
</mx:HBox>
The part of the XML config file that is used to populate the
combobox.
<mainconfig>
<vulnstatus>
<status>Open</status>
<status>In Progress</status>
<status>Closed</status>
</vulnstatus>
</mainconfig>
Now, when a user selects an item from a separate datagrid, on
change I have it run the following function. The function reads in
the data, parses it and compares the "status" value from the
datagrid info with the "status" options in the XML config file.
When it matches, it sets the index number for the combobox so it
shows the right data. My problem is below the function.
public function parseMSVulnStatus(evt:Event):void {
var xmlMSV:XML = XML(msdetailed.selectedItem); //the host
dataProvider item
//trace ("MS Vuln status = "+xmlMSV.status);
for ( var MSVi:Number=0; MSVi<_xmlVulnStatus.length();
MSVi++ ) { //loop over the items in the dataProvider
var sDataValueCurMSV:String =
_xmlVulnStatus[MSVi].valueOf(); //get the current item.data value
if ( sDataValueCurMSV == xmlMSV.status ) { //compare desired
value to current item.data value
mx.controls.Alert.show("match found - MS Vuln status =
"+xmlMSV.status +" and MSVi = " +MSVi);
msstatus.selectedIndex = MSVi; //set the seletedIndex of the
combo box
else {msstatus.selectedIndex = -1}
if (msdetailed.selectedItem.falsepos=='Y')
{msfalsepos.selected=true;}
The problem. If the value from the datagrid is "Closed", it
shows the index as being "2" and sets the combobox index
appropriately and displays "Closed". The alert box is displayed
(for testing) to show the values.
If the value from the datagrid is either "Open" or "In
Progress", it does show the proper index as being either 0 or 1,
respectively and shows the alert box. However, the combobox appears
to be set to -1. I have verified the data is set properly in the
database (which is what populates the datagrid).
Any thoughts on this? Based on my alert box, it appears that
the data is seen properly and that it knows how to set the index of
the combobox.... it's just not happening (unless it's "Closed").
Thanks in advance.
Chrisyou could force a selected index using something like
mydatagrid.selectedIndex=0 or 1 try this pos i made for someone
beacause if you want to cange the value of field based on selection
this could be simpler by using an xml file with all the value for
each record in one object

Trying to write a Listener on a CheckBox to change the Model of a ComboBox
I am trying to change the list that appears in a ComboBox dynamically based on if a CheckBox is selected or not. I have multiple CheckBoxes and ComboBoxes being created in a loop based on a variable assigned at creation. Every tutorial i have seen writes out a listener that explicitly defines the checkbox instance but in my case i don't acctually know. My checkboxes are in an array of checkboxes as are the comboboxes as they are being created at runtime. Any help would be much apreciated this issue has been with me for two days now.
here is a snippit of my code in how i was implementing this:
int numButton = 17; //this is for testing only, this variable is set from another class normally
// these variables are defined private elsewhere in the class
JCheckBox PlayerByeCheck[] = new JCheckBox[numButton + 1];
JCheckBox PlayerHomeCheck[] = new JCheckBox[numButton + 1];
boolean PlayerOnBye[] = new boolean[numButton + 1];
for (int i = 1; i <= numButton; i++) {
PlayerByeCheck[i] = new JCheckBox();
PlayerHomeCheck[i] = new JCheckBox();
PlayerOnBye[i] = false;
// more code here for building the gui it is not important for this problem
// code to build the list starts here
for (int i = 1; i <= numButton; i++) {
((TableLayout)PlayerRosterPanel.getLayout()).insertRow(1, TableLayout.PREFERRED);
PlayerByeCheck.setOpaque(false);
PlayerByeCheck[i].addItemListener(this);
PlayerByeCheck[i].setName("PlayerByeCheck" + i);
PlayerRosterPanel.add(PlayerByeCheck[i], new TableLayoutConstraints(2, 1, 2, 1, TableLayoutConstraints.CENTER, TableLayoutConstraints.FULL));
//the comboox that i want to change
//---- PlayerTeamSelect1 ----
if (PlayerOnBye[i] = true) {
PlayerTeamSelect[i].setModel(new DefaultComboBoxModel(new String[] {
"ARI",
"ATL",
"BAL",
"BUF",
"BYE"
PlayerTeamSelect[i].setSelectedItem("BYE");
} else {
PlayerTeamSelect[i].setModel(new DefaultComboBoxModel(new String[] {
"ARI",
"ATL",
"BAL",
"BUF",
"CAR",
"BYE"
PlayerTeamSelect[i].setOpaque(false);
PlayerRosterPanel.add(PlayerTeamSelect[i], new TableLayoutConstraints(4, 1, 4, 1, TableLayoutConstraints.FULL, TableLayoutConstraints.FULL));
//more gui code here method gets closed
//Item Action Listener starts here this is where i am having the problem
public void itemStateChanged(ItemEvent e) {
Object source = e.getItem();
if (source == PlayerByeCheck[1])
int select = e.getStateChange();
if (select == ItemEvent.SELECTED)
PlayerOnBye[1] = true;
PlayerRosterPanel.repaint();
//repaint the window i think can't get the listener to work to see if this is the right way to do this
//i doubt it is
I have tried several different ways to write the listener, the example in the code above is following the java swing tutorial by explicitly defining the checkbox. I have tried to write the listener as i am creating the checkbox, which doesn't seem to work or i am wrting it wrong, which is entirely possible. Once the listener sets the value i think it should repaint the screen but i am sure that that is wrong right now as well. As my hunch is the repaint will reset the checkbox to DESELCTED the default value. I will come to that issue once i figure out how to get the listener working. Ideally i want to be able to set the listener for the checkboxes regardless as to how many there are. As stated above i am generating a list of checkboxes, comboboxes and other fields based on a variable that is defined in one of my objects. If the user selects checkbox 3 than combobox 3 should be changed, and the others should not. if the user selects all the checkboxes than all the comboboxes change.
thanks for any help. Still plugging along on it trying to figure this one out. -
Getting selected item from combobox itemrenderer and storing in object
Hi Guys,
Can anyone help me in this regard. Its very urgent.
I have a combo box itemrenderer in datagrid column. I want to get the user selected item from the dropdown of the row(s) (User may select values from combo box from multiple rows of datagrid) and corressponding values of all other columns of the rows and store it in an object . Then pass this object to database to update only those rows that user has changed.
I am able to get the selected item from combo box using "event.currentTarget.selectedItem" and corressponding values of all other columns of the rows using "valueSelect.ID", etc where valueSelect is object which contains data for datagrid. But am stuck up with, how to store the selected item value of the combobox and corressponding values of all other columns of the rows into an Object ?.
Can anybody help me with sample to store selected item from combobox and its corressponding values of all other columns into an object which i can send to db...?
Kindly help me in this regard.
Thanks,
Anand.Hi!
Are you using a collection of VO or DTO as the dataprovider of the combobox component?
If so, have you created some attribute there to control the user's selection in the combobox?
For instance:
private var selected:Boolean = false;
If your solution fits this approach, you may create a new collection that contains just the objects that were selected by the user, it means you can loop through the datagrid's dataprovider and only insert in this new collection those objects that have the attribute "selected" set to true.
For instance:
private function getSelectedRecords(datagridDataProvider:ArrayCollection):ArrayCollection
var newCollection:ArrayCollection = new ArrayCollection();
for each (var item:Object in datagridDataProvider)
if (item.selected)
newCollection.addItem(item)
return newCollection;
Afterwards, you may serialize this new collection with your back-end.
Hope it helps you!
Cheers,

ComboBox - Setting Selected Values from data
I am running into a problem in Flex 3 that seems to be
different from Flex 2. Maybe someone can help.
I have a function for setting a combobox selected item for a
location for a value when the titlewindow completes loading. The
value is a prior value from a prior save. In other words to set the
combobox a value from a prior session.
The locations xml file is loaded from a remote object
oncreationcomplete of the titlewindow. The setselectedvalue
function worked perfectly in Flex 2 but now only works in Flex 2
after the titlewindow is loaded. We tested this by running the
setselectedvalue function from a button click after loading.
The dataprovider length is showing 0 in our debugging. After
titlewindow up on screen the length is showing correct ( 35 ) - in
this case. Our viewxmlobject function is showing no xml. Shows xml
correctly after up on screen.
I have set the creationpolicy to "all". That did not help
either.
Any suggestions? Anyone. This is killing me. Spent two days
now trying to get back to working state.
private function SetSelectedValue_cbLocation(): void {
var xLocID:String = eLocationID.text;
//viewXmlObject( cbLocation.dataProvider )
for (var i : int = 0; i < cbLocation.dataProvider.length
; i++) {
//Alert.show( cbLocation.dataProvider
.locid, 'Location DataProvider', Alert.OK);
if ( xLocID == cbLocation.dataProvider.locid ){
cbLocation.selectedIndex = i;
break;
The combobox has the dataprovider set at design time.

opening a pop-up window (the title window)? If so, where is the
combo box located? In the main app or the titleWindow? What calls
the SetSelectedValue_cbLocation() function? -

How to get the selectedIndex from a combobox made by classFactory?
Dear All,
I am trying to get the selectedIndex or selecetedItem.banda_id when changing a combobox that is created by classFactory and it is inside a datagrid.
The code I have is:
MXML:

</mx:DataGrid>
Script:
private function getSalasFinHandler(event:ResultEvent):void
salas_fin_lst = new ArrayCollection(event.result as Array);
salas_fin_dg.dataProvider = salas_fin_lst;
myservice.getBandas();
combofac=new ClassFactory(ComboBox);
combofac.properties={dataProvider:bandas_lst, labelField:"banda_nome", prompt:"Selecione"};
I am using Remote Object to get the data from a DB, and it is working properly.
As I will update the datagrid cell values, I would like to update them on the DB.
In order to do that, I would need to access the banda_id value, that is part of the combofac dataprovider, I mean that this dataprovider has 2 columns, being banda_nome and banda_id.
The question is how to get the banda_id value, when I change the comobobox?
Many thanks in advance,
GinesDear harUI and kolinitcom,
Thanks for the your prompt response and guidelines.
I went to research a little bit more on the itemEditEnd and found a way to access the data inside the combobox.
The code for all application goes below. If you click on the button, it will show you all the datagrid data, plus the ID of the combobox when changed.
Thanks again,
Gines

Problems with linked ComboBoxes
Hi everyone, and thanks to those who will reply
It's been 3 days since i'm having the same problem :
I have 2 comboboxes in a JPanel, and the things to be displayed in the second one depends on the first (for example selecting 'Hewlett-Packard' in the first combo box display all HP model in the second one)
When i select a item in the first combobox, an actionPerformed is fired, and i can populate the second combobox. Unfortunately, the combobox disappear in my panel, but if i click on the place where it used to be, the popup list display correctly... !
I just want to know hox can i make it visible anyway. I've tried combobox2.repaint() method within the actionperformed method (combobox2 is the name of my second combo box as you've guessed), but it doesnt work...
Something else too : in my first list, if i select another vendor, the list in the second is not removed, but the list of workstation of the second-select manufacturer is appended... I've tried here the combobox2.removeall() method, but here again, no results....
this is my code :
public class DocPCConfig extends JFrame implements ActionListener, WindowListener

I've removed all the things I found useless, but maybe i've removed too much ;-) I hope that this code is enough.
Thanks for your help (can you send a copy of your answers at : [email protected] - if you're too lazy to do this that's not a matter, but i don't know how i can find my post in all these posts... so that'd be cool ;-)Thanks Martin
that makes sense now was driving me mad as I couldnt find anything saying it wasnt supported, makes sense seeing as its a flash server. Annoyning thing was it was playing in the content viewer locally when I previewd the folio you would think that would not be the case if it was not supported. Im going to try the rtmp links in a player in a web page and view it on the ipad out of curiosity and ill let you know. Out of interest have you done anyting with imported html into indesign as part of your folios ? I havent as yet but am curious to know how it holds up ?
Thanks again
Neil
