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.

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.
