Question

I’ve got a JDialog that’s created and set to visible whenever the button is clicked.
My problem is that the button keeps the focus and doesn’t give it to the JDialog.

Is this a normal behaviour or there’s something wrong going on ?

Answer 1

JDialogs aren’t modal (are “modeless”) by default:

Creates a modeless dialog without a title and without a specified Frame owner.

Try constructing it as:

new JDialog(owner, title, ModalityType.APPLICATION_MODAL);

(Or the equivalent super() call if you’re subclassing JDialog. Or whichever modality type you want.)
