Hi
I have a JTable with 2 columns, there are other attributes of the JTable which are hidden from the user. Now,the second column values depend on all these other attribute values. For eg, one of them is a boolean, the other is a IPAddress value and the third a Date/ Time value. Depending on these values passed, the second column should be able to set its data.
Now what I need to know is :
1. I need to set up a combobox in the second column for the date/time attributes. How do I go about to do this ?!!
2. How do I manipulate the TextField of the JTable such that it can accept the format of an IP address ?!!
3. How do I get to set up a checkbox in the 2nd column if the dependent attribute is a boolean value ?!!
Basically, how do I make a single cell of the second column to accept different data types ?!!
Your help and suggestions are greatly appreciated !!
Thanks
Meghna

Meghna,
Read this excerpt from Brett Spell's book "Professional Java" and I guess it would help you answer your questions.
