When a component is added to the compartment, it is placed to the right of any components that were previously added to the compartment. If setLayout is not called, then the BorderLayout manager is used (because that's the default layout manager for a JFrame window).ĥ FlowLayout Manager 5 The FlowLayout class implements a simple one-compartment layout scheme that allows multiple components to be inserted into the compartment.

Import the appropriate package.Ĥ To assign a particular layout manager to a JFrame window, call the setLayout method as follows: setLayout(new () In the above code template, replace by one of the layout manager classes (e.g., FlowLayout, BoxLayout, BorderLayout, GridLayout), and replace by zero or more arguments. The BoxLayout class is in the javax.swing package. If a programmer adjusts a component's size (e.g., by changing a label's font size), the layout manager takes that into account and adjusts the layout accordingly.ģ Layout Managers The five most common layout manager classes:ģ The five most common layout manager classes: FlowLayout BoxLayout BorderLayout GridLayout GridBagLayout Except for BoxLayout, all of these layout manager classes are in the java.awt package. If a user resizes the window, the layout manager takes that into account and adjusts the layout accordingly. It then tries to fit the components neatly into the container. The layout manager looks at the size of its container and the sizes of the container's components.
