![]() Most applications do not call this method directly. The preferred height to lay out the container's components is the greatest preferred height of the components, plus twice the vertical gap, plus the top and bottom insets. The preferred width to lay out the container's components is the total preferred width of each of the components, plus (ncomponents + 1) times the horizontal gap, plus the left and right inset, where ncomponents is the number of components in the container. PreferredLayoutSize public Dimension preferredLayoutSize(Container target)ĭetermines the preferred size of the target container using this flow layout. Returns the minimum dimensions needed to lay out the subcomponents of the specified container. The minimum height needed to lay out the container's components is the greatest minimum height of the components, plus twice the vertical gap, plus the top and bottom insets. The minimum width needed to lay out the container's components is the total minimum width of each of the components, plus (ncomponents + 1) times the horizontal gap, plus the left and right inset, where ncomponents is the number of components in the container. MinimumLayoutSize public Dimension minimumLayoutSize(Container target)ĭetermines the minimum size of the target container using this flow layout. ![]() This method is called when a container calls its layout method. This method lets each component take its preferred size. Lays out the container argument using this layout. LayoutContainer public void layoutContainer(Container target) This method is not used by the flow layout manager. The alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, or FlowLayout.CENTER.įlowLayout public FlowLayout(int align, int hgap, int vgap)Ĭreates a new flow layout manager with the indicated alignment and the indicated horizontal and vertical gaps.ĪddLayoutComponent public void addLayoutComponent(String name, Component comp) This value indicates that each row of components should be right justified.Ĭreates a new flow layout manager with a centered alignment and a default 5-pixel horizontal and vertical gap.Ĭreates a new flow layout manager with the indicated alignment and a default 5-pixel horizontal and vertical gap. This value indicates that each row of components should be left justified. This value indicates that each row of components should be centered. ![]() Flow layouts are typically used to arrange buttons in a panel.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 take its natural (preferred) size.ĬENTER public final static int CENTER = 1 Public void removeLayoutComponent(Component comp) Ī Flow layout arranges components in a left-to-right flow, much like lines of text in a paragraph.
