Method Details

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
