I\'m using DocumentFilter to restrict input as integer or decimal. And the code I post here is working well for that.

Can anybody help me about how to restrict the i

Answer 1

Based on MadProgrammer answer I tested editing his "replace" function in "MyIntFilter" class to:

    @Override
    public void replace(FilterBypass fb, int offset, int length, String text,
                AttributeSet attrs) throws BadLocationException {

    Document doc = fb.getDocument();
    StringBuilder sb = new StringBuilder(2);
    sb.append(doc.getText(0, doc.getLength()));
    sb.replace(offset, offset + length, text);

    if (test(sb.toString())) {
        if (sb.length() < maxLength + 1) { //test string size
            super.replace(fb, offset, length, text, attrs);
            }
        }
    } else {
        // warn the user and don't allow the insert
    }

}

it worked fine for me.
