Retaining focus

Hi,

I have two required JTextFields with FocusListeners (I extend FocusAdapter). Before losing focus on the first field I want to check the value so my focusLost() performs a check and if it is unusually low (but still legal) I put up a JOptionPane.showConfirmDialog() asking to confirm the data YES or NO. If they click NO I want to retain focus so I perform a requestFocus() on the text field before returning to the focusLost() method but it doesn't work, focus still transfers to the next JTextField.

QUESTION - What is the proper way to retain focus?

Thank you, I will try to put some Duke Stars on this question.

yeah what your trying makes sense but doesn't work; I've tried it before.One suggestion would be to disable (setEnabled(false) everything else. Would that work for you?

Swing related questions should be posted in the Swing forum.You can use an IputVerifier. Check out this example from the Swing forum. It shows how to popup a dialog: http://forum.java.sun.com/thread.jspa?forumID=57&threadID=776107

Hi,

I tried to keep my example simple but I see now must reveal that there are other text fields and combo boxes on the screen. I am quite sure the user would subvert my logic by clicking on another field in the window after fixing the data and thus the next focus receiver would be different and I wouldn't know if or what object I had disable focus on previously. Does that seem like a trap to you as well?

Thank you.

Hi,

I will test this approach. I had some difficulty with this approach before but I was testing for the condition from within the shouldYieldFocus() method. I know I encountered the issue of putting up a dialog from within the verify() and turned off the verifier but I think a design flaw in the software kept me from being successful. I know a little more now and maybe I can get this to work this time. I'll reply again.

Thanks for responding.

I find that drinking Red Bull helps me retain focus or it makes me jittery I can never remember.PS.
