Hi.

it is a bit hard to explain what i am trying to do, but i will try.
I have a program i wrote, which is running all the time through a connection and calculate things.
And i want to open a JFrame for verificating a password for making some operations in it.
I have managed to create the JFrame with the user and password fields and the buttons.
but i have trouble making the main program / JFrame to wait for the user.

i am looking to make some sort of:
String inputValue = JOptionPane.showInputDialog("Please input a value");

or:
boolean verified = MyOptionPane.waitForVerification();
which opens a JFrame for the user to enter the user and password.

i hope i made myself clear enough here.

Thank you.

Use a JDialog instead of a JFrame, and

setModal( true ) ;

A modal dialog will freeze execution till you answer it :-)

Not sure why it's called "modal" the dictionary doesn't really help either...something about:

Modal : Something with logical Modality
Modality : The state of a Modal object

bah...language recursion ;-)

So if you set the dialog modal, the program will wait until that dialog is no longer visible (hide() or user closes it)

Good luck!

Tim.
