JScrollPane scrollPane = new JScrollPane(tArea,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS) īelow are the methods in JscrollPane Class. The component position is controlled with a pair of scrollbars. JScrollPane(Component c, int vsPolicy, int hsPolicy)Ĭreates a scroll pane with the specified component. JScrollPane scrollPane = new JScrollPane(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS) Ĥ. JScrollPane(int vsPolicy, int hsPolicy)Ĭreates a scroll pane with the specified scroll policies. JScrollPane scrollPane = new JScrollPane(tArea) ģ. When the component content is larger than the view, then horizontal and vertical scrollbar appears. JScrollPane scrollPane = new JScrollPane() Ĭreates a scroll pane with the specified component.
It can have both vertical and horizontal scrollbars when needed.įtDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) JScrollPane( )Ĭreates an empty scroll pane (no viewPort). Constructors of JscrollPane class are of two types Parameterized and Non-Parameterized, they are further classified as below: 1. The dimensions of it are undermined by the input values to these constructors i.e. The Sole purpose of the constructor of this class is to create a scroll pane. columnHeading – Used to scroll vertically.rowHeading – Used to scroll horizontally.

We create 5 JLabel components named “l1”, “l2″… “l5” and then add them to the JFrame by the method this.add(). Program 1: The following program illustrates the use of FlowLayout by arranging several JLabel components in a JFrame, whose instance class is named as “Example”.removeLayoutComponent(Component comp): Used to remove the component passed as argument from the layout.īelow programs will illustrate the Example of FlowLayout in java.setAlignment(int align): used to set the alignment for this layout.getAlignment(): Returns the alignment for this layout.The title you want to set is passed as a string. setTitle(String Text): This Method is used to set Title of JFrame.JLabel(String text): It will create a JLabel instance with the specified text.FlowLayout(int align, int HorizontalGap, int VerticalGap ): It will Construct a new FlowLayout with given alignment, the given horizontal and vertical gap between the components.FlowLayout(int align) : It will Construct a new FlowLayout with given alignment.The horizontal and vertical gap will be 5 pixels.FlowLayout(): It will Construct a new FlowLayout with centered alignment.The horizontal and vertical gap will be 5 pixels.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.
