table that allows only one row [message #446834] Fri, 03 December 2004 15:28 Go to next message

Is it possible to create a table that only allows to add and to display
one row? I would like to have some kind of text field that can show three
values (like a table with three resizable columns), but I only want to
display one row. Is there another control I could use?
TIA, Mikael

Hi Mikael,

Why don't you just use a table?
Since you will have to add the table items to the table programmatically,
which is of course done using the constructor:

TableItem(Table parent, int style)

It is always up to you how many rows a table will have.
For example, when the user clicks on the add button (or whatever mechanism
that triggers the updating of table), just check the table for the number of
rows ( using Table.getItemCount() )
if the count is zero, just create the new TableItem. If the count is one,
clear up the table (using Table.removeAll()) and then add the row you want.

As far as I know, there is no control specially designed for that purpose
(It won't make sense, since the same thing is perfectly and easily
implementable using a Table!).
You might consider writing your own widget using a couple of Labels,
Composites and Sashes, yet the same result can be achieved much faster using
the table.

regards,

Mani

Actually, a SashForm with a bunch of Text widgets as children will do this
quite easily:

SashForm form = new SashForm(shell, SWT.HORIZONTAL | SWT.SMOOTH);
for (int i = 0; i < 3; i++) {
Text text= new Text(form, SWT.NONE);
text.setText("column "+i);
}

Yes, About the compsoite, I assumed that there would be a header visible for
each column (so that you have to combine the header AND the Text/Label in a
composite)...

thanks anyways,

Mani
