![]() ![]() But if the components are wrapped they disappear: With a GridBagLayout it looks perfect with everything next to each other. With a BorderLayout and the JPanel placed in the center the buttons appear at the top because the JPanel expands to the size of the ContentPane of the JFrame: I have tried other LayoutManagers aswell, but I couldn't fix this problem yet. The problem is that the JPanel takes the lower half of the JFrame and the Glue the upper half: If the window is wide enough to fit both buttons next to each other, it almost seems centered:īut if its too small you can clearly see my problem: GetContentPane().add(Box.createVerticalGlue()) GetContentPane().setLayout(new BoxLayout(getContentPane(), BoxLayout.Y_AXIS)) SetDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) Here is a simple SSCCE, which demonstrates my problem, because i dont think i can explain it well: import javax.swing.* I tried to use a BoxLayout with a VerticalGlue, but it doesn't center it completely. MainFrame.I have a JPanel containing a few components, laying them out with a FlowLayout, so that they will wrap if necessary and i want to center this JPanel in a JFrame. StatusLabel = new JLabel("",JLabel.CENTER) HeaderLabel = new JLabel("",JLabel.CENTER ) MainFrame = new JFrame("Java SWING Examples") SwingLayoutDemo swingLayoutDemo = new SwingLayoutDemo() This class inherits methods from the following classes −Ĭreate the following Java program using any editor of your choice in say D:/ > SWING > com > tutorialspoint > gui > Returns a string representation of this FlowLayout object and its values. Sets the vertical gap between the components. Sets the horizontal gap between the components. Removes the specified component from the layout. Void removeLayoutComponent(Component comp) Returns the preferred dimensions for this layout given the visible components in the specified target container. Returns the minimum dimensions needed to layout the visible components contained in the specified target container.ĭimension preferredLayoutSize(Container target) Gets the vertical gap between the components.ĭimension minimumLayoutSize(Container target) Gets the horizontal gap between the components. Void addLayoutComponent(String name, Component comp)Īdds the specified component to the layout. For example, to the right in left-to-right orientations.Ĭonstructs a new FlowLayout with a centered alignment and a default 5-unit horizontal and vertical gap.Ĭonstructs a new FlowLayout with the specified alignment and a default 5-unit horizontal and vertical gap.įlowLayout(int align, int hgap, int vgap)Ĭreates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps. Static int TRAILING − This value indicates that each row of components should be justified to the trailing edge of the container's orientation. Static int RIGHT − This value indicates that each row of components should be right-justified. Static int LEFT − This value indicates that each row of components should be left-justified. ![]() For example, to the left in left-to-right orientations. Static int LEADING − This value indicates that each row of components should be justified to the leading edge of the container's orientation. Static int CENTER − This value indicates that each row of components should be centered. Class Declarationįollowing is the declaration for class −įollowing are the fields for class − The class FlowLayout components in a left-to-right flow. ![]()
