Please help! How to add a combobox on a jtable

Hi, I have seen on google and here many codes to add a combobox in a jtable but none of them seem to work, I need the urgently.
My problem is that I must add a comboBox or a JComboBox to a cell inside a JTable on a predefined column. It means that on the column 2 I must add diferent comboboxes for eac row. How can I do it, please help.

The celleditor is the component shown and the cellrenderer is the first render of a component in the cell and dont have to be the same jcombo box?
The code on ther post does this:?
returning a diferent combobox for all the cells on the column depending on the row selected, but as long as only one cell can be selected at a time it seems to hace different jcomboboxes added a time?
Is there anyway to render any combobox with different values, my program must let the user chose the teacher it want to teach a definen subject, so the combo must have the teacher of a subject loaded on a database, the combos are not constants. I guess I can manage to use the way you showed me, but is there anyway to render a combo just by adding it to a cell! maybe doing changes to the tablemodel or things like that?

How to put a JPanel in a JTable

I have been having problems with using a JPanel in each cell in a column of a JTable. I have a class "myPanel" which extends JPanel and has an overridden paint() function. In each row I want the "myPanel" to be displayed in the cell.
I've read all the documentation(that I could find online), and have searched for a while, but have not found the right way to do this.
I currently have defined myPanel like this:
class myPanel extends JPanel implements TableCellRenderer{
public Component getTableCellRendererComponent( ... ) {
repaint();
public void paint(Graphics g) { ... }
So, In my paint function I am not sure which cell(in the table) needs to be painted, but in the getTableCellRendererComponent, I know the cell to be rendered but I can't actually paint anything(I dont have a Graphics object to paint on).
SO either I get my graphics painted into every cell in the column identically, or I don't see anything in the cells. How do I paint differently in different cells.
Should I be using the object passed into getTableCellRendererComponent directly?
And I don't think there is a default renderer for a panel which would display the panel.
Any hints would be wonderful, as I can't get this to work.

You should use your myPanel with the params row and column as if the panel in that row and that column is the one to paint and return it from the method getCellRendererComponent, like in this code.
public Component getTableCellRendererComponent(...){
//....set the properties of your panel/CellRenderer as needed
//for displaiing the cell located in the row and column you get as //parameters,
//even adding or removing buttons or other stuffs from your panel
return this;
// you return the CEllRenderer itself !!! The table will do the painting work !!
That's it !!!
Do not use paint or repaint, you don't need it !!!

Thanks in advance

But did u mean this as the next problem,Which I will come across..Yes, the second setVisible(true) seemed to be producing a smaller frame behind the main frame.
And your JMenuBar is declared twice, but not sure if this will affect the code - haven't read it all.

How to add an image to a JPanel ?

hi,
do you now how to add an image to a JPanel ?
thanks a lot !

You can either use the Graphics method drawImage from the panel's paintComponent(Graphics g) method, or you can create an ImageIcon, with your Image in its constructor. And then create a JLabel, passing that ImageIcon in its constructor. Then, you can simple use the panel.add() method to add that JLabel.
For using the paintComponent method, check out the thread already posted above (I'll type it in again just in case)
http://forum.java.sun.com/thread.jsp?forum=31&thread=288769
If you want to use a JLabel, you can do something like this:
Image img;
JLabel label = new JLabel(new ImageIcon(img));
JPanel panel = new JPanel();
panel.setLayout(new FlowLayout());
panel.add(label);Val

                        Table.addNotify();
              br.close();
             if possible give me some examples.
thank you.

For every row you need to create a new Vector and add the data to that Vector. Then the Vector is added to the TableModel.
If you add 6 items to the single Vector, then you will get 6 columns. So you need to create 6 Vectors and add a single item to each Vector and therefore you will end up with 6 rows with 1 column of data.

How to add JPanel in JComboBox?

Hi.
How to add JPanel in JComboBox...?
Regards
Bilal

I do not know much about Cardlayout.
As far as I know, it is a layout which let you assign a serveral 'card' and exist together. By consider the order of the card, you could change the view of each page by using method- first, last, next etc. However, I would like to know what if I got a number of buttons, say A B C D E F, and having cards called a b c d e f,I know I could change from a to b, but what if I want to change from c to e by pressing the button E (assuming it showing the c card now).
Actually, I was able to create the code now which adding one JPanel to another now. First create a JPanel with prefer size, min max size.
then add a JPanel into the CENTER of the above JPanel, both using borderlayout.
But having a little difficulties, could I add more JPanel into the CENTER such that one overlapping each other, by those Buttons, through action and event, hide those which I do not want to show?
Like A B C buttons, a b c panels. When press A hide b c and show a, so on.
Could I use method like movetofront(something like that, forgot detail which read in a book) to do this?
Cheers

How to add the JTable results to an Object to save it in a file?

Hi... After i created a SAVE button and allow the user to enter a file name to save the results in the JTable, it didnt work. After the user entered the filename, the file was not created.
What is the type of the file the user should enter? eg. file.txt, file.doc or wat type?
When i use Vector, i added the JTable into the vector and i write the code 'out.writeObject(vector);'. Is this the right way?? Should i use vector or Object?? If i am suppose to use Object, how do i add the things in the JTable to the Object??
Thanks.

thanks... the file is created but the results in the file is not readable... how do i solve this??
I use vector and i added the JTable into the vector and the results have squares and unreadable symbols....
Thanks again....

How do I add a JCheckBox to a JTable - URGENT HELP NEEDED

Hello All,
This is kicking my butt. I need to create a JTable that I can dynamically add and delete rows of data to and this table must contain a JCheckBox which I can read the value of. I've been able to find examples out there that provides the ability to have a JCheckBox in the JTable, but do not also provide the function to add / delete rows from the JTable. I need to have both funtions in my table. Can somebody out there please help me with this?
Here's a simple example that I'm working with as a test to figure this out. This example has the functionality to add rows of data.
Thanks in advance.

I got it, I added the public Class getColumnClass to new DefaultTableModel(). Here it is for your viewing pleasure.

How to add ComboBox in Jtable Header

Hello everyone,
I want to add a Combox box in JTable Header .Basically it works as central access to whole table e.g. by selecting delete row in combo box then it should delete the current selected row.If somebody has any idea please share it.
Thanks in advance.

The individual headers are not Swing components and therefore do not respond to mouse events in the same way as Swing components. Why don't you just have a popup menu that is positioned over the currently selected row? If you want to apply an action to all selected rows then have a set of buttons placed above the table header.
