Filtering in Java Swing Table

Question

public void newFilter() {
    RowFilter<ListTable, Object> rf = null;
    //If current expression doesn't parse, don't update.
    try {
        rf = RowFilter.regexFilter(filterText.getText(), 0);
    } catch (java.util.regex.PatternSyntaxException e) {
        return;
    }
    sorter.setRowFilter(rf);

}

I'm using this filter from http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#sorting But this filter seems only able to filter int component on my table (Apart from the first col, all others are strings) . I simply want to create a Filter that leave any row with entered text. I'm relatively new to the language, Thanks very much for your help!

Wait, so your problem is that the filter is applied to the first column only? — Ordous, Jul 16 '14 at 10:27
Yes. The problem is Filter only apply to the 1st column http://stackoverflow.com/questions/1107911/how-can-i-filter-rows-in-a-jtable doesnt seems to help much — qkhanhpro, Jul 16 '14 at 11:57

Your filter is explicitly applied to column zero, the first column. As shown here, you can include all columns by omitting the indices parameter:

rf = RowFilter.regexFilter(filterText.getText());

Alternatively, you can include specified columns, e.g. columns one through three:

rf = RowFilter.regexFilter(filterText.getText(), 1, 2, 3);

A related example that combines filters is seen here.

Addendum: In helpful comments, @Ordous reminds me that correct usage hinges on the varargs feature, new in Java 5.

Thank you very much! I clearly didn't understand the use of filters well. – qkhanhpro Jul 16 '14 at 12:07
I'd give a +1 since the answer is correct, but I really don't like questions that are solvable by just quoting the Javadoc on the method *already used* by the OP... – Ordous Jul 16 '14 at 15:56
@Ordous: I tend to agree, but I also have a clear memory of stumbling over [varargs](http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html) when the feature was new to me. – trashgod Jul 16 '14 at 16:03
@trashgod True, it can be confusing. But if it says "indices of values to check" on an argument you supply, and you have a problem with some values not being checked, then that's the first place to look, possibly after the regex itself. – Ordous Jul 16 '14 at 16:17
