Hi there,
is it possible in RWT to have a table with multiline columns?
I've seen tutorials for SWT where this is done using PaintListeners and
thats not possible with RWT currently.
Thanks for any input on this.

Hello Austin,
I helped myself with the problem by implementing a ContentProvider and
LabelProvider which splits up the long text into multiple table rows.
The input is wrapped by the ContentProvider and then send as model-
elements to the table viewer. This aproach works quite well but it is not
possible to have TableEditors with this. That the only drawback we have.
But thanks for your input. :)

Hi Austin and Markus,
I also need a table with multiline columns, but I can't implement it.Can
you give me some hints or some exactly simple code?
Thanks,

Hi Cheney,
you could try a ContentProvider like this:
private static class MultilineContentProvider extends
ArrayContentProvider {
public Object[] getElements(final Object inputElement) {
if (inputElement instanceof List<?>) {
final List<Object> elements = new
LinkedList<Object>();
final List<Object> list = (List<Object>)
inputElement;
for (int i = 0; i < list.size(); i++) {
final Object pos = list.get(i);
final String[] lines = WordUtils.wrap
(pos.toString(),
100, "\n", true).split
("\n");
elements.add(lines[0]);
// Other lines
for (int j = 1; j < lines.length; j++) {
elements.add(lines[j]);
}
}
return elements.toArray();
}
return super.getElements(inputElement);
}
}
The code is not tested, since I removed the application specific party of
our application. So all places where Object is used was a business
specific class containing the data to present, but it should be quite
simple to adopt.
The WordUtils class is from commons-lang and wraps the content to display
at 100 characters.
