Good idea - here's a very simple replacement and an example that uses it to handle
large tables.
/**
* Removes all of the rows except headers
*/
public void deleteBodyRows() {
// walk backwards - more efficient for ArrayList.remove
for (int i = rows.size() -1; i >= headerRows; i--) {
deleteRow(i);
}
}
ExampleLargeTable.java

This is more generally useful and faster. I'll make the change and post it. Thanks --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
