Constructor Summary

GridAllocator()

GridAllocator(int numCols, int numRows)
Constructor specifying the number of columns and rows.

GridAllocator(int numCols, int numRows, boolean make)

Method Summary

Region	createRegion(double x, double y, double width, double height)
protected RegionDescriptionInt	createRegionDescription(int i, int j)
void	make()
Region[]	rectRegions(double widthCM, double heightCM, double fontSize) Compute the cells as rectangular regions associated with this grid based on the dimensions of the container it serves, provided to as centimeters and font height.
RegionDescriptionInt	setDescription(java.lang.Object which, GraphicalComponentInt child, GraphicalContainerInt parent) General indexing, such as int[] for a GridAllocator, which is supported differently by the different allocators.
