Hi, Does anyone know of an easy way of validating the JTextfield input. I would like to only permit numbers in the JTextfield, and deleting any character strings the user have entered. If possible, preventing the string to be displayed at all. thanks in advanced for your help. Sarone
hi sarone, write a utility class which extends javax.swing.text.PlainDocument and override the insertString method and define it the way you want.Finally set the document for ur jtextfield. Thanks, Sai
I'm thinking about a new battle cry. Maybe "Not in the face! Not in the face!" Any thoughts tiny ad?
