Method Detail

getNodeDimensions

public abstract Rectangle getNodeDimensions(Object value,
                                            int row,
                                            int depth,
                                            boolean expanded,
                                            Rectangle bounds)

Returns, by reference in bounds, the size and x origin to place value at. The calling method is responsible for determining the Y location. If bounds is null, a newly created Rectangle should be returned, otherwise the value should be placed in bounds and returned.

Parameters:

value - the value to be represented

row - row being queried

depth - the depth of the row

expanded - true if row is expanded, false otherwise

bounds - a Rectangle containing the size needed to represent value

Returns:

a Rectangle containing the node dimensions, or null if node has no dimension
