JFrame frame = new JFrame("MySpringDemp") įtDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) Ĭontainer contentPane = frame.getContentPane() It is used to calculates the preferred size dimensions for the specified container, given the components it contains. It is used to calculates the minimum size dimensions for the specified container, given the components it contains. It is used to calculates the maximum size dimensions for the specified container, given the components it contains. It Invalidates the layout, indicating that if the layout manager has cached information it should be discarded. It returns the constraints for the specified component. It returns the spring controlling the distance between the specified edge of the component and the top or left edge of its parent. GetConstraint(String edgeName, Component c) Has no effect, since this layout manager does not use a per-component string. Constraints, associates the constraints with the specified component.ĪddLayoutComponent(String name, Component c)
If constraints is an instance of SpringLayout. It specifies the width of a component's bounding rectangle.ĪddLayoutComponent(Component component, Object constraints)
It specifies the left edge of a component's bounding rectangle. It specifies the vertical center of a component's bounding rectangle. It specifies the bottom edge of a component's bounding rectangle. It specifies the top edge of a component's bounding rectangle. It specifies the horizontal center of a component's bounding rectangle. It specifies the height of a component's bounding rectangle. It specifies the right edge of a component's bounding rectangle. It specifies the baseline of a component. It is a Constraints object helps to govern component's size and position change in a container that is controlled by SpringLayout SpringLayout(): The default constructor of the class is used to instantiate the SpringLayout class. SpringLayout doesn't automatically set the location of the components it manages. If a constraint is added to create a new edge, than the previous binding is discarded. Every constraint is represented by a SpringLayout.Constraint object.Įach child of a SpringLayout container, as well as the container itself, has exactly one set of constraints associated with them.Įach edge position is dependent on the position of the other edge. Constraints are nothing but horizontal and vertical distance between two-component edges. MainFrame.A SpringLayout arranges the children of its associated container according to a set of constraints. 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.
