public class IGridView

extends View

implements LayoutManager, Target

IGridView consists of 9 panes; TOPLEFT (fixed size) TOPCENTER (horizontally scrollable, fixed height), TOPRIGHT (fixed size), MIDDLELEFT (vertically scrollable, fixed width), MIDDLECENTER (vertically and horizontally scrollable), MIDDLERIGHT (vertically scrollable, fixed width), BOTOTMLEFT (fixed size), BOTTOMCENTER (horizontally scrollable, fixed height), BOTTOMRIGHT (fixed size). A common Border separates the panes (default is BezelBorder.groovedBezel()).
