Constructor Detail


public DateHeaderGrid(DateGrid trkGrid,
                      int primDim,
                      int[] rangeTypes,
                      GridLineSpecification gridLineSpec)

trkGrid - The grid to be a header for
primDim - The primary dimension if this header. Does NOT have to be same as for trkGrid!
rangeTypes - The different date ranges (E.g. DateRangeI.RANGE_TYPE_DAY for the label rows. One range type for every row. Number of rows will be rangeTypes.length. See MutableDateRange.roundExpand(int).
gridLineSpec - The specification for the grid lines in the primary and secondary dimensins. Not null.
Method Detail


public DateCellRange getMergeRange(int r,
                                   int c,
                                   boolean useStartDate)
Should return a range that is in some way interconnected. This can be compared to merging cells to pose as one.

The returned DateCellRange will have a userObject that is a ImmutableDateRange and that represents the date range of the returned DateCellRange.

Note that the returned range can in the horizontal OR vertical dimension, but not both. This means that cells can only be merged in one dimension.

r - The row
c - The column
useStartDate - If the start or end date of the cell row should be used. AtStart dates when left or top and end dates when lower or right of the tracked grid.
The range of merged cells that c and r hits. The range can be just one cell. Not null.


public ImmutableDateRange getCellDateRange(DateCellRange cellRange,
                                           boolean includeTemp,
                                           boolean useSt)
Returns the date range for the cell range.

cellRange - The cell range. Not null.
includeTemp - If the temporary union in cellRange should be included.
useSt - If the start or end date of the cell row shoule be used. start dates when left/top and end dates when lower/right of the tracked grid.
The date range for the cell range.
