![]() The objects of Java's simplest layout manager are constructed from theĬlass FlowLayout in the package java.awt. Will only be creating and arranging buttons. Than one class of button our buttons are going to be objects constructedįrom the JButton class in the package javax.swing. Of the screen that can be "pressed" by clicking on a mouse. An object that is simple to create and display is a button, a region Here, however, we will examine only three.īefore we start to examine layout managers, we need something toĪrrange. Number of different layout managers and even allows you to create your Of these components can be controlled by a layout manager. If a container has more than one component, the position and size of each Lays out the container.13.3 Layout Managers 13.3 Layout Managers Public void layoutContainer( Container target) The minimum dimensions to lay out the subcomponents of the specified container Public Dimension minimumLayoutSize( Container target) The preferred dimensions to lay out the subcomponents of the specified container Public Dimension preferredLayoutSize( Container target) Removes the specified component from the layout. Public void removeLayoutComponent( Component comp) Public void addLayoutComponent( String name,Īdds the specified component to the layout. Sets the vertical gap between components. Sets the vertical gap between components and between the components and the borders of the Container. Gets the vertical gap between components. Gets the vertical gap between components and between the components and the borders of the Container. Sets the horizontal gap between components. Sets the horizontal gap between components and between the components and the borders of the Container. Gets the horizontal gap between components. Gets the horizontal gap between components and between the components and the borders of the Container Possible values areĪlign - one of the alignment values shown above Possible values are FlowLayout.LEFT, FlowLayout.RIGHT, FlowLayout.CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING. Vgap - the vertical gap between components Hgap - the horizontal gap between componentsĪnd between the components and the borders of the Container The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, ![]() Returns a string representation of this FlowLayout object and its values.ġ.2 Package-private pending API change approvalĬonstructs a new FlowLayout with the specified alignment and a default 5-unit horizontal and vertical gap. Returns the preferred dimensions for this layout given theĬomponents in the specified target container. Returns the minimum dimensions needed to layout theĬomponents contained in the specified target container. This value indicates that each row of components should be justified to the trailing edge of the container's orientation, 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.Ĭreates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.Īdds the specified component to the layout.Ĭomponents and between the components and the borders of the ContainerĬomponents and between the components and the borders of the Container. This value indicates that each row of components should be right-justified. This value indicates that each row of components should be left-justified. This value indicates that each row of components should be justified to the leading edge of the container's orientation, for example, to the left in left-to-right orientations. ![]() This value indicates that each row of components should be centered. Each line is centered.įor example, the following picture shows an applet using the flow layout manager (its default layout manager) to position three buttons:Ī flow layout lets each component assume its natural (preferred) size. It will arrange buttons left to right until no more buttons fit on the same line. The line alignment is determined by the align property. It arranges buttons horizontally until no more buttons fit on the same line. The flow direction is determined by the container's componentOrientation property and may be one of two values:įlow layouts are typically used to arrange buttons in a panel. Class FlowLayout įlow, much like lines of text in a paragraph.
