Sorry I was being a trifle glib when I said about multi-line support. Labels
can be used to provide multi-line support. Here is a code snipet.
class MessageBox extends Dialog {
public MessageBox(Frame parent, String s) {
super(parent, "Message Dialog", true);
StringTokenizer st = new StringTokenizer(s, "\n");
Panel pl = new Panel();
pl.setLayout( new GridLayout(st.countTokens(), 1) );
while (st.hasMoreTokens()) {
pl.add(new Label(st.nextToken()));
}
add("Center", pl);
Panel p = new Panel();
add("South", p);
p.add(new Button("OK"));
resize(200, 175);
setResizable(true);
}
public boolean action(Event e, Object arg) {
hide();
return true;
}
}
Hope this helps.
