When we click on a button named “left” for left alignment, the buttons on the window-pane should be aligned to the left.

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) 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. 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:

Components: Components are the GUI objects such as buttons, label, textfield, checklist. Container: Container is a class that contains all the components such as button, textfield, titlebar, menubar, etc.Ģ. Some of the basic concepts regarding AWT hierarchy are as follows:ġ. Java AWT: AWT is an API for building GUI or window-based applications.
