Foil 54 Layout of Components in a Panel

From Java Tutorial - Spring 1997 Part 3:Graphics and the Abstract Windowing Toolkit Peking Tutorial, Web Certificate -- Spring-Summer 1997. by Nancy J. McCracken,Geoffrey C. Fox


1 The various panels in a container are laid out separately in terms of their subcomponents
2 One can lay components out "by hand" with positioning in pixel space
3 However this is very difficult to make machine independent. Thus one tends to use general strategies which are embodied in 5 LayoutMangers which all implement the LayoutManager Interface. One can expect further custom LayoutManager's to become available on the Web
4 setLayout(new FlowLayout()); // creates a basic flow layout in your panel -- actually unnecessary as default
5 Other available LayoutManager's are GridLayout(), BorderLayout() (default for Frame's), CardLayout() (Used for dynamic layouts) and GridBagLayout() (the most flexible)
