Hi Guys,

I ussually dont post anything here often, just get everything off of everyone elses questions,
but I'm having a strange problem that im scratching my head over,

I have a JTable where I can Add and remove rows... This is just for testing purposes, I'm about to make a ingrediants program.
The thing is whenever I change one of the Comboboxes they all seem to change.. its really wierd,

Could Someone run this and help me out, this is probably a stupid mistake?

See my Code Below,

My Main

package doughtracker;

import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

/**

public class DoughTracker {

    static Dimensions dimensions;

    public static void main(String[] args) {
        dimensions = new Dimensions();
        try {
            // Set System L&F
            UIManager.setLookAndFeel("javax.swing.plaf.nimbus.NimbusLookAndFeel");
        } catch (UnsupportedLookAndFeelException | ClassNotFoundException | InstantiationException | IllegalAccessException e) {
            System.out.println(e);
        }

        Window window = new Window();
        window.window();

    }

}

At a quick look it seems that all the cells in Col 0 share exactly the same renderer and editor , so they should all look exactly the same all the time!

commented: That's how clones are made! +15

I am able to add and remove cells through, how would that work?

I noticed I deleted this when I posted the code,

This goes in table cell renderrer component.

Are you saying that the missing line was the fix for the problem (looks like it should be!), or do youy still have the problem with that line in place?

No I'm still having the exact same problem... the line was accidently removed when pasting to the forum.

I think you need to run it to understand what I mean. Like I said I'm more than likely making a stupid mistake but I don't know anymore

Sorry, I don't have the time to set up a multi-file project to try that...
Can you strip it down to a single small file that demonstrates the problem?

Quikly threw this together, run it click on the + button to add a few rows in the table and select somthing from 1 of the comboboxes,

They all change?

Renderer does not use latest value from model.

I thoought the actual value from the combobox is stored in the table model and can be obtained as any data stored in the table model itself?

OK, I've loaded and run your code.
The problem definitely seems to be in the shared renderer.
If you simply comment out the line (~135) that sets the renderer then the table uses a default text field renderer and everything works correctly.

When swing refreshes the table it uses your renderer (of which there is only one instance) to paint all the cells in col 0 that are not currently being edited. That renderer paints exactly the same thing into each of those cells.
You need the renderer to use the actual value from the table model, which is passed into the getTableCellRendererComponent method, but ignored in your code.

Just for fun I added a setSelectedItem(value);call into that method. That way the combo box has the right item selected when the renderer is called for each cell.

However it does not work when the cell hasn't had a value set yet. In that case you just get the value left over from the previous call, so to make it work you need to initialise each cell to a valid value from the combo box when the new row is added.

Man I'm Dumb,

Thanks,

How I have a question kinda related, How do i make the combobox disapear again if a user doesant finished selecting an item and does somthing else?

You need to click the table again for the combobox to dissapear...

Not sure exactly what behaviour you want, but if you set the editor but leave the default renderer then the combo box only shows when a cell is being edited and all the other cells just show their current value. That would be a normal behaviour in my opinion.

ps. Not dumb at all. We've all done stuff like that. Fortunately you could harness the power of castle DaniWeb.

Thank you for your help sir,
