Example 2 with WindowListener

use of java.awt.event.WindowListener in project android by JetBrains.

the class WelcomeScreenWindowListener method install.

    // That listener is an instance of anonymous class and our hack will stop working if
    // that class is removed or renamed. "DirectListener" is a fallback in case we don't
    // find an original listener.
