public void show(Desktop desktop,
                 boolean fill)
          throws java.lang.NullPointerException

Requests the dialog to be shown on the specified desktop.

The method does not return while the dialog is shown. During this period, all the input events are sent only to this dialog and its children. Beware that:

• If the current thread is used to read data or to communicate, these actions will not run until the dialog is hidden.
• If the current thread owns monitors, they will not be released. Other threads that need this monitor will wait until the dialog is hidden.

Overrides:

show in class Panel

Parameters:

desktop - the desktop

fill - true to fit the panel to the desktop size, false otherwise

Throws:

java.lang.NullPointerException - if desktop is null.
