Classes:

• Widget: This class is superclass for all jcurses widgets. For implementing a ne widget you must derive it. An jcurses widget is already used within a window. Its task ist to help it's WidgetContainer to layout itself, giving needed informations, to paint itself and to handle input. Handling input is needed only, if the widget has is an input widget ( examples are text input widget, list widget) and has currently focus, that is is selected by user to handle input. This selectig ocurrs by typing a special key (currenty 'tab') to switch between input widgets. All widgets are ordered in a hierarchy. An widget ...
• Window: This class is a jcurses implementation of an text based window. An window under jcurses is, differnt from other GUI libraries, not a widget, this contains a panel ( a the called root panel ), that contains all widgets. A window can, but doesn't must, have a border and a title. All windows under jcurses are managed in a stack, the topmost visible window window on the stack gets all input chars for handling, this is so called focus window. If an window are created, it gets automatically to the top of the stack and leaves the until an other window is created or explicitly brought to the top.
• BorderLayoutManager: This class is a layout manager that works like Swing's BorderLayout. Up to 5 widgets can be added to this layout at once, in the following positions: NORTH, SOUTH, WEST, EAST, and CENTER. Components in the outer positions are set to their preferred size, and the component in the CENTER is allocated the remaining screen area.
• PopUpMenu: This class implements a popup menu window. Such windows can be used for example to implemene menu bars ( currently not cantained in the library ). A popup menu window gives a user the possibility to select and ivoke an item from a list and is than closed. Separator items can be used as by MenuList described.
