Actually, (and I'm not trying to be awkward!) I have a use case that
might involve an algorithm...
I came across the lack of multiple check boxes when seeing how I'd
duplicate the result of this JSP method in Wicket...
String generateServiceTable(List services, int colSize, String listName) {
int cols = (services.size() / colSize) + 1;
StringBuffer sb = new StringBuffer();
sb.append("<table >\n");
sb.append("<tr>\n");
for (int i = 0, rows = 0; i < services.size(); i++) {
Service service = (Service) services.get(i);
if (rows == 0) {
sb.append("<td valign=top width=\"" + 100 / cols + "%\">\n");
}
rows++;
sb.append(
"<input type=\"checkbox\" name=\"" + listName + "\" value=\"");
sb.append(service.getName());
sb.append("\"");
if (service.isFree()) {
sb.append(" checked");
}
sb.append(">");
sb.append(service.getName());
sb.append("<br>\n");
if (rows == colSize) {
sb.append("</td>\n");
rows = 0;
}
}
sb.append("</tr>\n");
sb.append("</table>\n");
return sb.toString();
}
It basically blocks the generated controls into columns, e.g. 10 per
column, with each column surrounded by a <td></td> pair. The approach
that comes to mind is to override getPrefix/getSuffix, but does a
better approach come to mind?
