Hello,
I was reading the HoverExample supplied by eclipse in the hope of
applying their example to my Table.
I want to have special popups for particular cells in a row. But I
notice that in their code they use the command ".setData(...)" on each
TableItem which corresponds to an entire row, and not one particular cell in
a row.
Is there a way to have special popups for specific cells within a row?
Syntactically, I was hoping there would be a command like ".setData(index)"
where I could specify the index of the column to add a hover object to.
But, ".setData()" seems to affect an entire TableItem which is equal to an
entire row, so the popup would affect all cells in a row (which is not what
I want).
Any suggestions, or examples of code which manipulate cells in a table?
Thanks....

You are confused (may be I am). The setData method associates an Object
with your Widget, so you can retrieve "context" objects later.
To change the visible content in a specific cell inside a TableItem, you
use setText(int column, String text)
If you want to launch a different popup for each row, there is no
relationship with the setData method (you can use it for anything you
want). What you need is to know at what column you are located. (AFAIU)
and launch the apporpiate popup there, which could be a global one or a
TableItem data set by setData, or anything you like.
Note that there is a setData with a key argument also.
