Could someone point me in the right direction here please?
What is the best way to validate a text field which is for filenames? Should I just wait for entry confirmation and then validate or is it nice to create a general class which could be added as a listener to all appropriate text fields?
Also - in Eclipse when you create a new class it validates the filename on-the-fly -> you must enter a valid file/class name which doesnt already exist. Perhaps I would like to implement this - HOW??
