How to pause execution while JDialog is open

Question

How can I make my application pause when I open custom JDialog and after the dialog is closed to make continue again.

Answer 1

Simply use:

setModal(true);

I usually call it from within the constructor of the JDialog.

See the Javadocs on setModal(boolean).
http://java.sun.com/javase/6/docs/api/java/awt/Dialog.html#setModal(boolean)

That will cause execution to block on the current thread until the dialog box closes.

Alternatively, you can use:

setModalityType(Dialog.DEFAULT_MODALITY_TYPE);

It is equivalent to setModal(true) and technically the correct way to do it.

Answer 2

See the constructor of JDialog http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JDialog.html#JDialog(java.awt.Dialog,%20java.lang.String,%20boolean) . You can set the modality of this dialog. Setting modal=true will pause your application. you can also use the method 'setModal' http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Dialog.html#setModal(boolean)
