Run this code in Eclipse and we’ll get the following figure below. The code above shows the scenario when we use the X_AXIS layout. Set the window to be visible as the default to be false panel.add(Box.createRigidArea(new Dimension(0, 60))) Add buttons to the frame (and spaces between buttons) BoxLayout boxlayout = new BoxLayout(panel, BoxLayout.Y_AXIS) Set the Boxayout to be Y_AXIS from top to down Set the BoxLayout to be X_AXIS: from left to rightīoxLayout boxlayout = new BoxLayout(panel, BoxLayout.Y_AXIS) JFrame frame = new JFrame("BoxLayout Example X_AXIS") įtDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) * BoxLayout.X_AXIS, BoxLayout.Y_AXIS respectively. * A swing BoxLayout example with different Boxlayout axis parameters SwingBoxLayoutAxis.java package javaCodeGeeks The layout can be defined when the the the panel is added. After this operation, three buttons (Button1, Button2, Button3) are generated and added in the panel. Then a JPanel is added on this frame and we can set the accurate size of it. To compare the difference layout between these two settings, a JFrame needs to be created as the largest container. In X_AXIS, components are laid out horizontally from left to right, while in Y_AXIS vertically from top to bottom. In this example, we’ll compare the results of BoxLayout with two different axis options: X_AXIS and Y_AXIS. Swing BoxLayout example with different axis parameters Also, the alignment settings of different components will also have influence on the layout of the whole GUI. If you’re interested in the other two, you can refer to the official doc from Oracle here. As X_AXIS and Y_AXIS are more often used, we’ll show only examples with these two axes. For the axis, four different axes could be chosen: X_AXIS, Y_AXIS, LINE_AXIS, PAGE_AXIS. For the container target, it can be a frame, a panel or other containers to hold the components. Only one constructor is used by BoxLayout: BoxLayout(Container target, int axis), which will lay out components along the given axis. In BoxLayout, it puts components in a single row or a single column. In this article, we’ll focus on BoxLayout and go through the basic operation on it. In Java Swing and awt package, several layout managers are popularly used, such as BorderLayout, BoxLayout, CardLayout, FlowLayout and GridLayout. In Java Swing, layout manager is in charge of laying out different components in specific positions. In this article, we’ll discuss about Java Swing BoxLayout.
