NAME

       The IconBox widget class

SYNOPSIS

       #include <Xm/IconBox.h>

DESCRIPTION

       The  Icon  Box widget lays out its children on a grid with each child forced to be the same size and with the location of each child speci-
       fied as an X and Y location on the grid.

       The size of the Icon Box, its children, and the number of cells displayed are calculated as described below. The general idea is  that  all
       children  are  always  be shown and should be given their desired size whenever possible. The user may add or delete cells by resizing this
       window using the window manager widget.

       o    The preferred size is calculated by using the maximum desired child height or width and making sure that these are no smaller than the
	    minimum sizes. This size is multiplied by the number of cells along the axis and properly padded to come up with a preferred size. The
	    number of cells is the maximum of the largest cellX or cellY value and the minimum number of horizontal or vertical cells.

       o    If the Icon box is forced larger than its preferred size more cells are added at the bottom-right of the widget while the children all
	    remain at their preferred sizes.

       o    If	the  Icon  box	is  forced smaller than its preferred size each cell is forced to be smaller in order to allow all children to fit
	    within the Icon Box. All children will be forced to the same smaller size.

Normal Resources
       Name			Class		  Type			Init. Value
       horizontalMargin 	Margin		  HorizontalDimension	4
       minimumHorizontalCells	DefaultCells	  Int			8
       minimumVerticalCells	DefaultCells	  Int			4
       minimumCellHeight	MinimumCellSize   VerticalDimension	10
       minimumCellWidth 	MinimumCellSize   HorizontalDimension	20
       verticalMargin		Margin		  VerticalDimension	4

       All resource names begin with XmN and all resource class names begin with XmC.

horizontalMargin
verticalMargin
       The amount of space between each cell and its neighbor or the edge of the Icon Box.

minimumHorizontalCells
minimumVerticalCells
       The minimum number of cells to display in the horizontal and vertical directions.  This number of cells will always be displayed.

minimumCellWidth
minimumCellHeight
       The smallest size the cells are allowed to be in the direction specified.

Constraint Resources
       Name    Class   Type    Initial Value
       cellX   CellX   Short   XmIconBoxAnyCell
       cellY   CellY   Short   XmIconBoxAnyCell

       All resource names begin with XmN and all resource class names begin with XmC.

cellX
cellY
       The location of this cell in cell space. These coordinates may be any positive integer. They determine where this  widget  will	be  placed
       relative  to  its neighbors.  Having two children at the same cell X and cell Y location will result in undefined behavior. To place a cell
       at any empty cell, set cell X and cell Y to the value XmIconBoxAnyCell.

Convenience Routines
XmCreateIconBox - Widget creation convenience routine
       Widget XmCreateIconBox(
	    Widget parent,     /* Widget id of parent for IconBox */
	    String name,       /* Name of the created widget */
	    ArgList args,      /* argument list */
	    Cardinal num_args  /* number of items in argument list */
	    )

       To find out if a cell in the icon box is empty use the XiIconBoxIsCellEmpty function:

       Boolean XmIconBoxIsCellEmpty(Widget w, Position cell_x, Position cell_y)

       w	      the icon box widget

       cell_x	      the x location of the cell to check

       cell_y	      the y location of the cell to check

       This function returns True if the specified cell has no child in it, and False otherwise.
