Two questions:

1) Unselecting all rows in a table
How can I unselect all rows in a table? If I just created the table,
getSelectionIndex() returns -1 indicating that no row is selected. After the
user has selected a row however, I was not succesful to unselect that row
again: setSelectionIndex(-1) seems to be ignored...

2) I want to use a Table just for displaying data and the user should not be
able to do any manipulation. When I call setEnabled(false) however, fore-
and background color get greyed out. Is there another way to achieve a
similiar behavior without setEnabled() where colors still work?

Thanks,
Thomas

Table#deselectAll() is the proper method (I think). Double check that one.

Tables are non-editable by default. In fact, you really need to go out of your way to make them editable. I'm not sure why you would be having problems with this. Perhaps you could clarify exactly what is happening which is undesirable?

Thank for your answer. I was looking for unselect() and did miss deselect().

I think you're right that I must clarify what I mean with editable. When a
table is enabled, the user can select one row of a table item which will be
displayed in another color. This should not be possible in my appliation.
What I am doing right now is to deselect the row just selected by the user
as soon the table gets the focus. So in fact I want to prevent the table
from getting the focus without getting enabled.

When I remember my Microsoft Access days, you had the possibility to set the
properties "locked" and "enabled" on UI elements to achieve the behavior
described. Is there a similar concept in SWT?

This is trick only - you can have property 'locked' and 'enabled'
and change colors of table when this properties change
