Java: Summary - GUI Layouts 1 - FlowLayout, BorderLayout, GridLayout

Set the layout manager for a container p (usually a JPanel or Container) can be set with something like the following.

   p.setLayout(new FlowLayout());

Layouts (FlowLayout, BorderLayout, GridLayout)
FlowLayout - Arranges widgets left-to-right, top-to-bottom.
`flow =`	new FlowLayout();	Creates FlowLayout, centered with 5 pixel gaps.
`flow =`	new FlowLayout(align);	Specifies alignment (`FlowLayout.LEFT`, `FlowLayout.CENTER`, `FlowLayout.RIGHT`).
`flow =`	new FlowLayout(align, h, v);	Specifies alignment and horizontal (h) and vertical (v) gaps in pixels.
	p.add(widget);	Adds widget to the next left-to-right, top-to-bottom position.
BorderLayout - Lays out components in BorderLayout.NORTH, EAST, SOUTH, WEST, and CENTER sections.
`bord =`	new BorderLayout();	Creates BorderLayout. Widgets added with constraint to tell where.
`bord =`	new BorderLayout(h, v);	Creates BorderLayout with horizonal and vertical gaps sizes in pixels.
	p.add(widget, pos);	Adds widget to one of the 5 border layout regions, pos (see list above).
GridLayout - Lays out components in equal sized rectangular grid, added r-t-l, top-to-bottom.
grid =	new GridLayout(r, c);	Creates GridLayout with specified rows and columns.
`grid =`	new GridLayout(r,c,h,v);	As above but also specifies horizontal and vertical space between cells.
	p.add(widget);	Adds widget to the next left-to-right, top-to-bottom cell.
