JAVA布局（国外英文资料） GridBagLayout Set the component location free The pre-set layout is the setLayout () parameter empty, setLayout (null). Create a layout in the component (x, y) coordinates and width and height as parameters. The setBonds (int x, int y, int w, int h)) : the parameters are the coordinates and the width, the height. SetSize (int, int) sets the size of the component SetLocation (int, int) sets the coordinates of the component Example: Rectangle re = new Rectangle (10, 10, 50, 30); Button. The setBounds (re); FlowLayout The constructor: FlowLayout () : set up the order layout manager, by default the components on each row will be centered; FlowLayout (int) : specifies the alignment, no parameters, flowlayout.center, or 1: the components on each line will be centered; Parameter flowlayout.left or 0: left-aligned; Parameter FlowLayout. RIGHT or 2: RIGHT alignment. FlowLayout (int, int) : FlowLayout. LEFT LEFT, FlowLayout. Parameter 2: horizontal spacing between components, per pixel; Parameter 3: vertical spacing between components, per pixel. Methods: SetLayout () : associated the container with the layout manager; Getalize () : to get the alignment; Setaliting () : setting up the alignment; SetHgap () : set horizontal spacing; SetVgap () : set the vertical spacing. GridLayout The constructor: The GridLayout (int, int) parameter is the number of rows and the number of columns. If the number of rows, the number of columns and the actual discrepancy, satisfy the number of rows first. The GridLayout (int, int, int, int) parameter one, two: the number of rows and the number of columns; Parameter 3, 4: horizontal spacing and vertical spacing. The default horizontal spacing and vertical spacing are zero. Methods: SetHgap () : set horizontal spacing; SetVgap () : set the vertical spacing. Border layout The constructor: GridBagLayout () : creates a grid bag layout; GridBagConstraints () : creates a grid bag layout helper. Used to set the properties of the component
