Re: Add button to every new jtable row during runtime
 

Hi.

How about showing us the code you use to create your table, with your attempt at adding the button.

Here's hint - you are going to need two more columns in each row, one for add and one for update. That's one possible solution, but yours might differ.

In general, people won't help you unless you put in some effort, so at the very least, share your code, nobody will laugh at your efforts, they just want to see that you've really tried to do the work first.

Good luck,
Ewald

Hi.

I think you might be better served if you attached the code in a ZIP archive, that way whoever helps you can be sure to get it right.

You are going to have to put the buttons in some kind of ARRAY, or LIST : upload the code in the ZIP and I'll take a look at it.

Best regards,
Ewald

Awesome!

You are very close to an answer. I don't think giving you exact code is going to help you learn something, but I have a handy hint for you that's going to push you in the right direction:

The following section of code displays a main panel, filled with some buttons. If you click on one, it identifies itself. The buttons are added to a list at runtime, so, in theory, you can have as many buttons as you want. Using this, you can do the same in your code. Believe it or not, this piece of code creates 150 buttons :)

Please let me know if you managed to get your code working.

Best regards,
Ewald

no it didn't ring a bell :nonod::nonod:adding buttons is working fine .but giving them separate actionlister is difficult just give me hint where n how to put actionlistner in my code m stuck in it :embarasse.for example when i press the delete button of particular row it deletes it.and when i press the update button of particular row it should let me do hat i want to do... plz help me in a way that i should learn something . i agree with u that giving me exact code is not a good idea but atleast make me move in right direction .:confused:
