1.4 Frames
In Java terminology, a frame is a window with a title and a border. A frame may also have a menu bar. Frames play an important
role in the AWT because a GUI program normally displays a frame
when it's executed.

Learn More... |
1.15 SubMenu
SubMenu provides easy way of displaying menu items based on
SubMenuModel. Each item in a menu must belong to the MenuItem
class. It can be an instance of MenuItem, a submenu (an instance
of Menu), or a check box (an instance of CheckboxMenuItem). Learn More... |
1.16 NestedMenu
NestedMenu provides easy way of displaying menu items based on
NestedMenuModel. Each menu in a menu must belong to the Menu
class.and futher the nested menu must be belong to the menuItem
class .It can be an instance of MenuItem, a Nestedmenu (an
instance of Menu), or a check box (an instance of
CheckboxMenuItem). Learn More... |
1.17 Layouts in AWT
The layout of components within a container remains a
mystery.Layout manager classes are founded in the java.awt package
same as the classes used for displaying graphical components. Learn More... |
1.17.1 BorderLayout
The BorderLayout layout manager can handle up to five components.
Learn More... |
1.17.2 CardLayout
The CardLayout class lets you implement an area that contains
different components at different times.
Learn More... |
