Parameters:

evt - The action event that triggers an action. The ActionCommand of the event has to be an integer, encapsulated as a String, that identifies the event according to the modes in JaxoConstants.

Dispose the main frame and call JaxoLauncher.shutdown(exitStatus).

Parameters:

exitStatus - The exit status code.

updateSelectedTab

public void updateSelectedTab(JaxoTab old,
