Multiple lines of text in one tablecell? [message #447953]

Hi!

I wonder if it is possible to display text in a table in several lines?

I want to use a table to display the comments a user made to a list of
elements. Of course, this works quite fine with the comments presented one
line, but with lengthier comments its not very readable.

Thanks in advance,

Frank

I had the same problem and could not find any way to use a variable height table.
 
 i ended up doing it in absolute code, hope it of some use. I also added a move and size listener which both call the layout method for when the size changes.
 
 Major problem is that is does not scroll so my view sets the composite provided in create part layout to fill layout and adds a scrolled composite. Then create a new composite and fill it up with the layout method shown below and then set that as the input of the scrolled composite.
 
     protected void layout(Composite panel) {
 
         // make sure we have something to layout
         if (quoteItem == null)
             return;
 
         // get the quote as that is where the data model is
         Quote quote = quoteItem.getQuote();
 
         // if not one then give up
         if (quote == null)
             return;
 
         // get the size of the area to fill up
         Rectangle client = panel.getClientArea();
 
         // going to allocate a quarter of it to the quote item name
         int col1 = client.width / 4;
         int col2 = client.width - col1;
 
         // start at the top
         int y = 0;
 
         // find out how many rows are in the table model
         ConfigWarning[] warnings = quote.getConfigWarnings();
 
         // each row has two columns, the first is the name
         // of the quote item, the next the problem description
         for (int i = 0; i < warnings.length; i++) {
             
             // build the name from the data cell
             Label name = new Label(panel, SWT.WRAP);
             name.setText(warnings[i].getQuoteItemName());
             name.setLocation(0, y);
             Point p1 = name.computeSize(col1, SWT.DEFAULT, true);
             name.setSize(p1.x, p1.y);
 
             // and the description
             Label desc = new Label(panel, SWT.WRAP);
             desc.setText(warnings[i].getWarningMessage());
             if (warnings[i].isLockPrevention())
                 desc.setForeground(red);
             desc.setLocation(col1, y);
             Point p2 = desc.computeSize(col2, SWT.DEFAULT, true);
             desc.setSize(p2.x, p2.y);
 
             // move down the number of pixels of the tallest
             // column
             if (p1.y > p2.y)
                 y += p1.y;
             else {
                 y += p2.y;
             }
         }
     }
