Swing layout in java
Swing layout : In our simple Swing program, we specified the location of our various components inside the window with some constants: BorderLayout.CENTER , BorderLayout.SOUTH etc. In general, a window has a particular layout , and that when we add a component to the window, we add it in a particular position in that layout. BoxLayout BoxLayout arranges components either horizontally or vertically in a panel. You can control alignment and spacing of the components. Complicated layouts can be made by combining many panels, some with horizontal layout and some with vertical layouts. Several classes are typically used: javax.swing.BoxLayout , javax.swing.Box , and javax.swing.Box.Filler . To Create a JPanel with BoxLayout Choose either a horizontal layout ( BoxLayout.X_AXIS ) or vertical layout ( BoxLayout.Y_AXIS ) for a JPanel. JPanel p = new JPanel(); p . setLayout(new BoxLayout( p , BoxLayout.Y_AXIS)); p .add( some_component );
