![]() The following example will create 1 JPanel (main panel) contain 5 JPanel (item panel), Each item of this panel will be set FLowLayout with a different alignment and contains a JLabel (with text and icons) to demonstrate the alignment of their. We will consider 2 The following example: Khi ComponentOrientation là left-to-right This code shows how to create a Java FlowLayout that flows left and has horizontal spacing of ten pixels and vertical spacing of five pixels: FlowLayout flowLayout new FlowLayout (FlowLayout. In this article we will learn that.Įven our objects are arranged in Container (ComponentOrientation) là left-to-right/top-to-bottom, with FlowLayout it is left-to-right. When you use will not distinguish the difference between LEFT and LEADING, RIGHT và TRAILING. ![]() Use FlowLayout because it's quick and easy. When a container size is changed (eg, when a window is resized), FlowLayout recomputes new positions for all components subject to these constraints. If the component's orientation is RIGHTTOLEFT, the LEADING alignment means RIGHT. The LEADING alignment may mean either left or right it depends on the orientation of the component. It will arrange buttons left to right until no more buttons fit on the same line. The following five constants are defined in the FlowLayout class to represent the five different alignments: LEFT, RIGHT, CENTER, LEADING, and TRAILING. ![]() Flow layouts are typically used to arrange buttons in a panel. create and layout buttons that will control deckītLayout( new GridLayout( 2, 2 ) ) įor ( int i = 0 i < controls.As you already know how to align the objects in a Layout, namely at all FlowLayout mentioned it. arranges components from left-to-right and top-to-bottom, centering components horizontally with a five pixel gap between them. implements LayoutManager, Serializable A flow layout arranges components in a left-to-right flow, much like lines of text in a paragraph. It will arrange buttons left to right until no more buttons fit on the same line. JLabel label3 = new JLabel( "card three" ) Ĭard3.add( new JButton( "North" ), BorderLayout.NORTH ) Ĭard3.add( new JButton( "West" ), BorderLayout.WEST ) Ĭard3.add( new JButton( "East" ), BorderLayout.EAST ) Ĭard3.add( new JButton( "South" ), BorderLayout.SOUTH ) Ĭard3.add( label3, BorderLayout.CENTER ) ĭeck.add( card3, label3.getText() ) // add card to deck Flow layout is used to layout buttons in a panel. ![]() set up card3 and add it to JPanel deck return the alignment value for this layout see java.awt. JLabel label2 = new JLabel( "card two", SwingConstants.CENTER ) ĭeck.add( card2, label2.getText() ) // add card to deckThis layout gives you a lot more control than FlowLayout does in that you can: Align the components along a left, center, or right. CENTER, FlowLayout.LEADING, or FlowLayout.TRAILING.set up card2 and add it to JPanel deck ![]() JLabel label1 = new JLabel( "card one", SwingConstants.CENTER ) ĭeck.add( card1, label1.getText() ) // add card to deck set up card1 and add it to JPanel deck Public class FlowLayoutDemo extends JFrame You can align the components left, right or center (default). The value of the alignment argument must be one of FlowLayout.LEFT, FlowLayout.RIGHT, or FlowLayout.CENTER. This is the most basic layout manager, components are placed from left to right as they were added, when the edge is reached the components are put on the next line. unlike GridLayout each component size can vary and components can be added in any order. Allows components to be arranged left-to-right or top-to-bottom in a container ![]()
