meka.gui.core.MaximizationFixWindowListener

All Implemented Interfaces:

WindowFocusListener, WindowListener, WindowStateListener, EventListener

extends WindowAdapter

Provides a work-around for platforms where the maximization of frames (eg JFrame) results in strange behaviors. Linux is such a platform, with popup menus (and the selectio) getting their coordinates completely wrong.
