[Rob Camick]

You can try using: Table Button Column

[sohaib maroof]

i tried this but i didn't figured it out how to enable jbuttons in jtable to get clicked. when i click on them i got -1 as row no and -1 as column no . how can i set it right any one tell me please m stuck

[Rob Camick]

i tried this but i didn't figured it out how to enable jbuttons in jtable to get clicked.

Use the DefaultTableModel. All cells are editable by default.

Otherwise you need to override the isCellEditable(...) method of the TableModel to return true.

[sohaib maroof]

i m using defaultTableModel the problem is when i click on any row in jtable i get its column n row number but when i press on button i get -1-1 means its not getting pressed now postpartum another program i hope i get it from it what i want .

Object value = jTable1.getValueAt(row, column);

when the compiler comes to that point i get out of bound exception -1

[Rob Camick]

I gave you working code that deletes a row.

If you need more help post your SSCCE.

[sohaib maroof]

i do not know your site do not let me attach rar file .how should i attach my code?

[Rob Camick]

We don't want a .rar file or your application. We want a SSCCE.

Your SSCCE will be about 20 lines of code.

It will take a couple of lines of code to built a JTable with a few rows of data in it.

It will take a couple of lines of code to create an Action that displays the data in the row clicked.

Its takes one line of code to add the button editor to the column. (if somebody wants to test it, they will need to download the ButtonColumn class from the link given above).

It will take a few more line of code to create the Jframe and add the table to it.

[sohaib maroof]

hi can you please run my program in your netbeans please download my code from this link i will be very thank full to you http://www.megaupload.com/?d=TB719I1D

[sohaib maroof]

if you look at my code you will see its not deleting the particular code where as it should

[sohaib maroof]

i get this error when i press on delete button

any one here

[Rob Camick]

please help me for GOD sake

You get what you give.

You haven't given us a SSCCE to work with!!!

I am not going to debug your custom renderer and editor. It is not an easy task to create these classes.

I already gave you a link to my blog which has a working renderer/editor which took me days to get working by looking at various solutions posted around the web. The blog even gives code for deleting a row when using this class.

My patience has run out!

[sohaib maroof]

i dont what i did that ran your patient out . anyways thanks for help

[Rob Camick]

I dont what i did that ran your patient out

You ask for help.

I gave you working code.

You ignore working code!

[sohaib maroof]

i told you i used this code and its not working for me why would i ignore it .i do not know how to use the code in given in this site . for you editing my code isn't a big issue yet you not doing it but its your call i cant force you to edit my code .thanks anyways

[Rob Camick]

i told you i used this code and its not working for me

So why would I post code that isn't working? Do you think the problem might be your code? I suggested you post a SSCCE showing how you used this code. I even outlined the steps needed to produce the SSCCE.

You didn't post the SSCCE. Instead you added some more verbal description which didn't help. You then complained that nobody was helping.

I again asked for the SSCCE and you posted a SSCCE using your old code. I'm tired of making suggestion 2/3 times!!!

Good luck with your next question.

[Paul Clapham]

This is your problem?

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: Array index out of range: -1
at java.util.Vector.removeElementAt(Vector.java:558)
at javax.swing.table.DefaultTableModel.removeRow(DefaultTableModel.java:463)
at com.company.librarySystem.bm.ui.NewJFrame.selectedCol(NewJFrame.java:59)

Then renderers and editors have nothing to do with it. This just means that your code called the removeRow() method of DefaultTableModel and passed it a row number which wasn't in the table. The bottom line in that stack trace fragment indicates which line of your code was at fault. Start debugging there.

thank you i am checking on it and tell you how it went
