With the setLayout() functions, we are setting the layout as flowlayout. When creating the class instance, we need to see the buttons so adding the buttons to a container in the class constructor itself. In the above code, we had declared 3 buttons with the help of JButton as lb, rb, and cb. L.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) Main Method of Flowlayout in Java: import javax.swing.* Public void actionPerformed(ActionEvent event) This constructor will align by the specified align field as RIGHT, LEFT or CENTER and also provides the option for adding horizontal gap and the vertical gap between components.įollowing is an example of flow layout in java:. FlowLayout(int align, int horizontalGap, int verticalGap): Constructs a FlowLayout with a given alignment and with a given horizontal and vertical gap between the components. FlowLayout(int align): Constructs a FlowLayout with a given alignment with 5 pixels gap between the components. FlowLayout(): Constructs an instance of FlowLayout as center-aligned and with 5 pixels gap between the components. setTitle(String text): Sets the title of the container with the given text. addLayoutComponent(): Adds the particular component to the layout. getAlignment(): Gets the alignment of the layout of the container. setAlignment(int align): Sets the respective alignment to the layout of the container. There are many types of layout manager available, each with its own capabilities and specific tasks: Layout Manager: A layout manager is an object that implements the LayoutManager interface to determine the size and position of the components within the container. It contains a menu bar and title bar and can contain other components as well.ĥ. The panel does not contain a menubar or titlebar but can contain other components like textfield and buttons.Ĥ. It creates a space for an application where all the components can be fit in. public void setVisible(boolean status): defines the visibility of the component by default, it is false.ģ. public void setLayout(LayoutManager m): defines the layout manager for the component. public void setSize(int width, int height): sets the component’s width and height. public void adds (Component c): adds a component on this component. There are some basic components functions such as: to the right for the left to rightīefore deep-diving into FlowLayout in Java details, let us revise some basic topics required for FlowLayout : TRAILING: It will be at the trailing edge of the container, i.e. to the left for the left to right orientation. 
LEADING: It will be at the leading edge of the container, i.e.CENTER: It aligns components to the center.RIGHT: It aligns components to the right.LEFT: It aligns components to the left.
The “align” property determines the alignment. FlowLayout uses some default settings such as center alignment with five pixels gaps between components horizontally and vertically.
When you do not select any layout, then the layout will be set to flow.
FlowLayout is the default layout provided by the layout manager. Of components increases than the window size, then by default, Java enables FlowLayout to arrange the components to fit in the windowpane. FlowLayout is one of AWT’s layout managers used in applets to arrange the components in a manner from left to right, just like words in a paragraph.
