Hello,

I have a tableviewer with cells that are not-editable.
BY default cells in the first column can be selected. How do I make the table completely not selectable?

I can only find ways to select the entire row, or to select also other columns....(using SWT.FULL_SELECTION...etc..)

Thanks!!

The intuitive choice would be to set the enablement property of the
underlying widget to false.

If viewer.getTable().setEnabled(false) does not what you want to might
consider to effectively stop selection by transforming them in empty
selections, see e.g.

http://wiki.eclipse.org/index.php/JFaceSnippets#Snippet004Hi deSelection

for an example to start with (To realize what you want: Just call

v.setSelection(StructuredSelection.EMPTY);

*unconditionally* within the mouse-listener, i.e. remove the if-part.).

This would have the draw back that you can't even scroll the widget
which is very often not the desired behavior.

<nod>, I understand that, but the exact use-case of the OP was not clear
to me (which is often the case, if people are not describing more
precisely their intentions). Sometimes this is exactly what you want,
sometimes not. Therefore, and with the second situation in mind, I added
the

"If viewer.getTable().setEnabled(false) does not what you want"

part ;-)

Thank you both, that was so helpful.

So since my table needed scroll behavior and
viewer.getTable().setEnabled(false) works but it also locks the scrollbar I used
v.setSelection(StructuredSelection.EMPTY);
inside a mouselistener, which works with no problem

Thanks again!
