public void show()
If the dialog is modal and is not already visible, this call will
not return until the dialog is hidden by calling hide
or
dispose
. It is permissible to show modal dialogs from
the event dispatching thread because the toolkit will ensure that
another event pump runs while the one which invoked this method
is blocked.
