public class IlvGridFlowLayout extends GridLayout implements SwingConstants
IlvGridFlowLayout
is an extension of GridLayout
that lays out the
components of a container in a rectangular grid. The container is divided into equal-sized
rectangles and one component is placed in each rectangle. The class IlvGridFlowLayout
automatically computes the number of rows and columns by first making the components flow
along either the horizontal or vertical axis. When no more components will fit along
the flow axis, the layout adds grid cells along the orthogonal axis as needed to
accommodate the overflow components.
The fact that IlvGridFlowLayout
has a preferred flow axis means that panels
using this layout work better in certain contexts than others. For example, a panel
with a horizontal IlvGridFlowLayout
will layout nicely when the panel is
placed in the north or south areas of a BorderLayout
. A panel with the same
layout will layout less nicely when it is placed in the east or west areas of a
BorderLayout
. Conversely, a panel with a vertical
IlvGridFlowLayout
will layout nicely when the panel is placed in the east or
west areas of a BorderLayout
, but will layout less nicely when placed in
the north or south areas of a BorderLayout
.BOTTOM, CENTER, EAST, HORIZONTAL, LEADING, LEFT, NEXT, NORTH, NORTH_EAST, NORTH_WEST, PREVIOUS, RIGHT, SOUTH, SOUTH_EAST, SOUTH_WEST, TOP, TRAILING, VERTICAL, WEST
