getting the selected cell, or other way of putting a link in a table cell [message #118376]

Hi,
I apologise for asking what appear to be very simple questions, but I
really am struggling to find an answer in google or the jfaces docs...

I would really like to be able to know which cell is selected in a
TableViewer or alternatively insert a link into the cell which I would
attached a listener to, but I can't find much on it...

Any ideas?

Thanks,

T

Tom,

the underlying table widget does not support the concept of cells.
To work around this, you could try to use mouse listeners and derive
the selected cell from the x/y coordinates. The CellEditor code does
something similar, look there for more info.
If the amount of data to display is rather small, you may be better
off with a custom widget, e.g. composed out of Link widgets with an
appropriate layout.

I made a custom table widget and i put links in it. I followed the
approach Rudiger mentioned. It also supports having text which scrolls
multiple lines. I have not had time to package it and genericize it but
works for me so far. Probably a bit of work for you to implement not sure.

To use it, you subclass this class:
http://code.google.com/p/inqle/source/browse/trunk/org.inqle .ui.rap/src/main/org/inqle/ui/rap/widgets/AScrolledTable.jav a

Also need to have this class:
http://code.google.com/p/inqle/source/browse/trunk/org.inqle .ui.rap/src/main/org/inqle/ui/rap/widgets/AScrolledWidget.ja va

An example implementation is here
