i have an applet with 10 fields in it. i need an action listener such that when you click on a particular field, a variable should be assigned to a value. once the cursor is out of the same field, the variable should be re assigned to the old/default value.
i am able to code the assigning part. please help in re-assigning the variable to old or default value once anything is clicked or selected out of that field.
If these are text fields, then the "action listener" you're looking for is a Focus Listener. The events it supports are "focus gained" and "focus lost", which are what you described. The tutorial is here: How to Write a Focus Listener.
