-
-
-BorderLayout is the default layout for the window objects such as JFrame, JWindow, JDialog, JInternalFrame etc. BorderLayout arranges the components in the five regions. Four sides are referred to as north, south, east, and west. The middle part is called the center. Each region can contain only one component and is identified by a corresponding constant as NORTH, SOUTH, EAST, WEST, and CENTER.
-
-Constructors:
-
-BorderLayout(): It will construct a new borderlayout with no gaps between the components.
-BorderLayout(int, int): It will constructs a border layout with the specified gaps between the components.
-Commonly Used Methods:
-
-toString(): Returns a string which is representation of the state of border layout.
-getLayoutAlignmentX(Container parent): Returns the layout alignment along the X-axis.
-getLayoutAlignmentY(Container parent): It will returns the layout alignment along the Y-axis.
-removeLayoutComponent(Component comp): This method is used to remove the specified component from the borderlayout.
-getVgap(): Return the vertical gap between the components.
-getHgap(): Returns the Horizontal gap between the components.
-setHgap(int hgap): It is used to set the horizontal gap between the components.
-setVgap(int vgap): It is used to set the vertical gap between the components.
-Below Programs will illustrate the BorderLayout class:
-
-Program 1: The following program creates JButton components in a JFrame, whose instance class is “BorderLayoutDemo”. We create 5 JButton and then add them to the JFrame by using add() method. We will set the size and visibility of the frame by using setSize() and setVisible() method respectively. The layout is set by using the setLayout() method.
