Working with Combo boxes in JTable in swings

Hello everyone,
I am working on swing components. We are designing a swing based platform for our company. I have a case where i have to use comboboxes in a jtable. I have seen a lot of topics on this but i have an issue with that. We have to implement a type ahead feature in these comboboxes where if we type any key the items in the table which start with that alphabet or sybol are selected. We can see this by default in regular comboboxes but i have been unable to implement this in the jtable. I have tried various ways like adding listeners etc. and none of them are working. This is my code for the cell renderers for these comboboxes
public class MyComboBoxRenderer extends JComboBox implements TableCellRenderer {
public MyComboBoxRenderer(Vector items) {
super(items);
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
if (isSelected) {
setForeground(table.getSelectionForeground());
super.setBackground(table.getSelectionBackground());
} else {
setForeground(table.getForeground());
setBackground(table.getBackground());
setSelectedItem(value);
return this;
public class MyComboBoxEditor extends DefaultCellEditor {
public MyComboBoxEditor(Vector items) {
super(new JComboBox(items));
Can anyone who has faced a similar issue help me regarding this.
Thanks in advance

Hi,
Have you tried the Swing forums at java.sun.com? This is the Java Studio Enterprise IDE Forum, so you probably won't get much response here.

Also, what IDE tools are you using?

Need help getting Apple Extreme to work with Be box

Anyone able to give an idiots guide to getting Apple Extreme to work with Be Box wireless modem?
Used to have Orange (Wanadoo) broadband with Livebox wireless router, which i had my AE wired up to and it worked fine. Signed up with Be* and managed to get their wireless router working and communicating with my Mac OK. When i hooked up AE the green light came on but i can't manage to get my Mac to find it.
Any help would be very appreciated.
Thanks.

Hello Orang Hutan. Welcome to the Apple Discussions!
What is your connectivity goal for the 802.11n AirPort Extreme Base Station (AEBSn)?
o Connect it directly to the Be Box wireless router via Ethernet, or
o Connect it wirelessly to the Be Box's wireless network?
If it is to go the wireless route, do you want the AEBSn to extend the wireless range of the Be Box?

Problem in event handling of combo box in JTable cell

Having trouble with combo box.

What im trying to do is put a string array into this combo box called jComboBoxParts how do i make it show? Right now when i load it, all i see is "Item1..."Item2...etc". Here is my code.
String[] partsString = { "oil can", "windshield", "tires", "v6 Cylinder head", "fuse"};
JComboBox[] jComboBoxParts = new JComboBox[partsString.length];
for(int i=0; i < partsString.length; i++)
jComboBoxParts[i] = new *JComboBox(*partsString);
with the bolded work i get an error. Please help.

That's ugly in so many ways...
This:
JComboBox[] jComboBoxParts = new JComboBox[partsString.length];does not do what you think it does. Instead, it creates an array of JComboBoxes initialized to the length of elements in your string array. So instead of a single JComboBox capable of holding 5 elements (which is what you were trying to do), you created 5 JComboBoxes capable of holding n elements.
What you want to do is something like this:
import javax.swing.*;
class Demo extends JFrame {
private JComboBox box;
public Demo() {
    initComponents();
private void initComponents() {
    String[] items = { "oil can", "windshield", "tires", "v6 cylinder head", "fuse" };
    box = new JComboBox(items);
    this.getContentPane().add(box);
    this.pack();
    this.setSize(200, 60);
    this.setLocationRelativeTo(null);
    this.setDefaultCloseOperation(EXIT_ON_CLOSE);
    this.setTitle("Combox Box Demo");
public static void main(String[] argv) {
    SwingUtilities.invokeLater(new Runnable() {
      public void run() {
        new Demo().setVisible(true);
}Another alternative, if you don't have the array of strings available when you instantiate your JComboBox, you could do something like this:
String items = { "oil can", "brakes", "windshield", "tail light", "something else", "blah", "more blah" };
for( String item : items )
myJComboBox.addItem(item);

Strange behaviour with combo boxes.

Has anyone else noticed strange behaviour of combo boxes with applets?
What happens is that on selecting the combo drop down, the dialogue the combo is sitting on moves behind its parent window. You just end up seeing the combo list, and no dialogue. Select a combo item, and sometimes the dialogue reappears, and sometimes it is still hidden.
I've only seen this whilst running an applet in browsers. In Eclipse I don't see the behaviour.
The behaviour is also very intermittent.
I'm using Java Plug-in 1.6.0_10-rc2, Using JRE version 1.6.0_10-rc2 Java HotSpot(TM) Client VM, on Windows Vista, Google Chrome browser.
I'd raise it as a bug, it certainly seems quite serious, but I don't have a reliable test case.
I have a work around, on all my dialogues with combo's on them, I have setAlwaysOnTop(true). Not really the correct behaviour though.

Drop down menu or combo box in jtable

Hi there I nee urgent help I have a jtable and I am collecting information to populate the table dynamically, the problem is I some of the strings that populate certain cells is longer the the width of the cell in a particular column, I thought I could use a combo box and split the strings up so I could have some type of drop down menu showing the information, but when I populate the combo box and instantiate the defaultcell renderer with the combobox it sets all cells in that column with the same information I would like to have it displaying the actual information for every row within that column
or if you can give me any ideas as to how I can avoid this happening or maybe an alternative method of showing these long strings in the table some kind of drop down.
Kind Regards Michael

the problem is I some of the strings that populate certain cells is longer the the width of the cell in a particular column,Set a tooltip to display the entire text of the cell. Here is a simple example;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class TableToolTip extends JFrame
     public TableToolTip()
          Object[][] data = { {"1234567890qwertyuiop", "A"}, {"2", "B"}, {"3", "C"} };
          String[] columnNames = {"Number","Letter"};
          JTable table = new JTable(data, columnNames)
               public String getToolTipText( MouseEvent e )
                    int row = rowAtPoint( e.getPoint() );
                    int column = columnAtPoint( e.getPoint() );
                    Object value = getValueAt(row, column);
                    return value == null ? null : value.toString();
          JScrollPane scrollPane = new JScrollPane( table );
          getContentPane().add( scrollPane );
     public static void main(String[] args)
          TableToolTip frame = new TableToolTip();
          frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
          frame.setSize(150, 100);
          frame.setLocationRelativeTo( null );
          frame.setVisible(true);
}If you want to get fancier than you could set the tooltip text only when the width of the text is greater than the width of the column. Here is an example of this is done with a text field. You would need to modify the code to refer the to table for the text string and the TableColumn for the width.:
JTextField textField = new JTextField(15)
     public String getToolTipText(MouseEvent e)
          FontMetrics fm = getFontMetrics( getFont() );
          String text = getText();
          int textWidth = fm.stringWidth( text );
          return (textWidth > getSize().width ? text : null);
textField.setToolTipText(" ");
I thought I could use a combo box and split the strings up so I could have some type of drop down menu showing the informationIf you want to proceed with this approach then check out this posting:

Combo Box in JTable

Is there a way to make one column in a JTable a ComboBox so that user can choose between 2-3 items?

Problem with Combo Box in a Dialog Box

I have a dialog box that includes a combo box.
For some reason the combo box shows up under the first text box. In other words, the combo box is not separate from the first field. It has the following:
ComboBox with Sequence showing, then Enter Identifyer
Textbox URL
Textbox Enter Resource 1
Textbox Enter Resource 2
Textbox Enter Resource 3
Textbox Enter Resource 4
Textbox Enter Resource 5
It's putting the combo box in the first text field...it should be
ComboBox with Sequence showing
URL Textbox

Enter Resource 1 Textbox
Enter Resource 2 Textbox...

Filtering my DataGridView with Combo Boxes

Hello everyone! I have recently started working with windows form application and I must say it is really
awsome! I have came up with a project but I came across a little problem and I hope some of you might help me!
I have established a local database and managed to connect it to a DataGridView, awsome I can see my database
in my windows form! I have also made 7 combo boxes, each with its strings in it, then i added a button that should filter the data grid view according to the strings the user selected in the combo boxes. My question is, how do i do that? I mean how do i make
the button fillter my DataGridView according to the strings selected in my combo boxes?
Hope for a quick answer, sorry for my english and lack of knowledge in windows form!

Maybe you could go this way:
Populate the combobox manually, first adding "All", then adding the items from industryGroupsDataSet.Tables[0].
Add a BindingSource between companiesDataSet.Tables[0] and dataGridView1.DataSource.
In the SelectedIndexChanged event of the combobox, alter the Filter property of the BindingSource. If the selected index is zero ("All"), set the Filter to null, otherwise set the filter to String.Format("groupID = '{0}'", cmbBxGroupFilter.SelectedValue).
You may also have a look at these too:

Trouble with combo box

I am using a combo box with the code below, but each time I
arrive on this
screen that displays cbTREATMENT, the combo box first draws
itself with the
default style, then applies my style, which looks a bit ugly
onscreen.
Anything I can do to rectify this?
Thanks.
cbTREATMENT.setStyle( "fontSize", "13" );
cbTREATMENT.setStyle( "color", "0x000000" );
cbTREATMENT.setStyle( "fontWeight", "bold" );
cbTREATMENT.setStyle( "fontFamily", "arial" );
cbTREATMENT.dropdown.rowHeight = 18;
cbTREATMENT.dataProvider=["","name1","name2","name3];
cbTREATMENT.text=vTREATMENT;

Thanks for the reply, but I'm not sure what you mean, can you
explain any
further?

Display issue with Combo Boxes and Logo

Hi All,
I am facing a couple of issues with my dashboard:
1. Combo boxes display - I have placed a series of combo boxes one below the other. During the preview, when I click on the first combo box, the values spread below. That is, the labels, and options of the next combo box are also visible. The options in the combo box are not seen clearly. I have tried many permutations and combinations with "Bring Forward +" and "Send Back -" but none of them seem to work. For example, keeping the first combo as bring forward and next one as send back etc. Can you please help me in this regard?
2. Logo - I have used image component and embedded a logo from my local system. Later I saved the xlf in the repository. When I import the xlf from the platform, it displays the logo fine. But however, this behavior is not constant. It sometimes doesn't show the image. Do I have to save the image also in the repository? or in a common shared folder? If I embed the logo does it not mean that the xlf hold the copy?
Any help in this regards is highly appreciated.
Thanks and regards,
Sandeep.

Hi:
For your question
1) Do you need your combox overlapped? I tried to overlap my comb box and preview it, seems works fine for me. it only chooses the first comb box. But I am suggesting that if you want to show/hide the different combox in the same position at run time, you can try to control the visibility by some other component.
2) The answer is NO, the image embedded in the image component will be saved to xlf file, there is no need to save it individually. Try to clean your cache files in your machine and do it again.
Hope it helps.

Help with combo boxes

I am currently building a site with flash / dreamweaver and
am attempting to add two or three combo boxe that will display data
and pictures from a database. Any ideas or assistance would be much
appreciated...
Many thanks in advance

Sunil,
I'm attempting to use the data binding technique but I'm perhaps not understanding exactly where this should go. For now I'm fine with having a static array that just lives locally on the page. Each of my combo boxes are being populated using the
mx:Array --> mx:Object logic.
I need to fire off an event to a function that is able to determine which selection(s) from the combination of the two combo boxes were chooses. I'm accomplishing that by using selectedIndex property of the combo boxes id. I then have 'n' number of unique Array Collections that are basically a three dimensional array containing the numeric percentage that I need to display graphically. I need my function to be able to choose the appropriate Collection based on the combination of selected index(es) and then update my column chart accordingly.
My other confusion is how to do use my data binding at the chart level. So my page is really nothing more than two combo boxes and chart that I need to change dynamically as the selections in the combo boxes changes. Eventually I will use a webservice to connect to a .jsp page that is using DAO to retrieve the values from the database but right now I'm fine with fetching them locally just so I'll know I'm on the right track.
If it would help I can include the snippet of the code that I'm working on.
Thanks for your help

Problem with combo boxes and the reset button in certain situations

Hi Everyone,
i have a problem to make the reset-button function properly in an what-if analysis dashboard.
The dashboard uses two combo boxes that are not visible at the same time. In my application the second combo box only appears when a dedicated menu (label based menu button) has been activated.
So i have combo box 1 when menu A is active an dand combo box 2 when menu 2 is active.
After starting the dashboard initial values are fine. If you then directly change to menu 2 (seeing combo box 2 with
the correct default value) and press the reset button, the dashboard returns to the initial view, showing
the menu 1 with the correct default value. If you now switch back to menu 2, you will see, that the combo box 2
is empty (i.e. nothing selected).
I also tracked the destination cells for the combo box value results as well as the source cells for the "selected item" and the
destination cells for the "Insert Selected Item". All this values seem to be correct. Therefore i assume that
this is an issue of event handling. Maybe the combo box 2 does not refresh its selected value because it is already
invisible when the values are restored.
This case can easily be simulated by placing two combo boxes and a push button (that changes the visibility of
the combo boxes) and the reset button on the canvas.
Maybe someone can help. I am able to provide a test xlf, if neccessary.
Thanks,
Oliver
P.S. I am using Xcelsius SP4 (Version 5.4.0.0)

Hello Debjit_Singha_86,
thank you for your support. At the moment i have the following setting:
label based menu
- General: Insertion Type "value" from a list of ID's for the menu-items to a dedicated cell (current menu ID, say tab1!$A$1)
- Behavior: Selected item (position) fixted to item 1
hidden combo box
- General: Insertion Type "position" to a dedicated cell with the current choice (say tab1!$B$1)
- Behavior: Selected item (position) to the same cell (tab1!$B$1)
Can you give me a hint on how to connect the two components according to your solution, so that the label based menu sets the default for the hidden combox box only in case, that the reset button is pressed?
Thanks,
Oliver
