The following is an example to left align components vertically with BoxLayout − Example package my įtDefaultCloseOperation(JFrame. The reason all components are right aligned is that you reset the layout of the JFrame to FlowLayout.RIGHT here: FlowLayout three new FlowLayout (FlowLayout.RIGHT) setLayout (three) This supercedes the earlier call to center align components. After that set left alignment of components which are already arranged vertically using Component.LEFT_ALIGNMENT constant − JPanel panel = new JPanel() It is the default layout of the applet or panel. Constructors of FlowLayout class FlowLayout(): creates a flow layout with centered alignment and a default 5 unit horizontal and vertical gap. addLayoutComponent (): It adds the specific component to the layout. setTitle (String text): Sets the containers title using the provided text. The horizontalGap and verticalGap arguments specify the. getAlignment (): Returns the containers layouts alignment. The alignment argument must have the value FlowLayout.LEFT, FlowLayout.CENTER, or FlowLayout.RIGHT. The default options for FlowLayout are center alignment and. setAlignment (int align): Adjusts the alignment in accordance with the containers layout. When there are more components than there is an increase in the size window, Java by default allows FlowLayout to organize the components so that they fit in the windowpane. FlowLayout(LEFT) - left justified with default 5-pixel horizontal and. One of AWT's layout managers, FlowLayout, is used in applets to organize the components, from left to right. FlowLayout(int align, int hgap, int vgap). The Java FlowLayout class is used to arrange the components in a line, one after another (in a flow). FlowLayout(RIGHT) - right justified with default 5-pixel horizontal and vertical gap. The components are arranged from left to right in the order in which they appear, i.e., in the order they are added. Now, create a Panel and add some buttons to it. If the container is wider than the combined width of the objects, then the row of objects is left-aligned, centered, or right-aligned depending on the alignment. Swing library is an official Java GUI toolkit released by Sun Microsystems. * = new public class microGUI If you are asked to define a concrete class called Main that implements Inter3, what are the methods that have to be overridden: * (1 Point) O mi O mi, ma m1, m2, m3 Om1, m2, ma 11.09ġ7 1 3 The statement that needs to be used to show the red box around the above frame is? * (1 Point) setBorder(new LineBorder(Color.red, 15)) O setBorder(new TitledBorder(red, 15)) setBorder(new TitledBorder(Color.red, 15)) setBorder(new LineBorder(red, 15))ġ8 The statement that sets the font name for button "b1" to "Times New Roman", the font style to italic, and size to 20 is: * (1 Point) O b.Font(new Font("Times New Roman", Font.ITALIC, 20)) b.setFont(new Font("Times New Roman", Font.ITALIC, 20)) b.setFont(new Font("Times New Roman", ITALIC, 20)) b.setFont(Font("Times New Roman", ITALIC, 20)) ġ9 * An interface can extend more than one interface (1 Point) True FalseĢ0 Which of the following statements can correctly change the background color of the button "b1" to yellow * (1 Point) b1.setBackground("yellow") b1.setForeground("yellow") O b1.setForeground(Color.yellow) O b1.setBackground(Color.To align components vertically, use the BoxLayout − JFrame frame = new JFrame() įrame.getContentPane().setLayout(new BoxLayout(frame.getContentPane(), BoxLayout.Y_AXIS)) A class does not implements all the methods declared abstract in the super class A class implements more than one interface.įill in the blanks so that this program displays a Frame: import java.swing. import import import import import import. Each JPanel object is initialized to use a FlowLayout, unless you. * Be default, the components in the FlowLayout manger are (1 Point) O center-aligned right-aligned D left-aligned None of the given choicesġ2 A class has to necessarily be declared as abstract class if * (1 Point) thing A class overrides a method from super class. Although components can provide size and alignment hints, a containers layout.
