Method Detail

hasCellSpans

boolean hasCellSpans(int rowIndex,
                     int columnIndex)

Returns true if has cell spans the specified cell at rowIndex and columnIndex.

Parameters:

rowIndex - the row index of the specified cell

columnIndex - the column index of the specified cell

See Also:

getCellSpans(int,int)

getCellSpans

Cell getCellSpans(int rowIndex,
                  int columnIndex)

Returns the cell that spans the specified cell at rowIndex and columnIndex.

Parameters:

rowIndex - the row index of the specified cell

columnIndex - the column index of the specified cell

Returns:

the cell that spans the specified cell

hasCellSpans

boolean hasCellSpans(int firstRow,
                     int lastRow,
                     int firstColumn,
                     int lastColumn)

Returns true if has some cells spans the specified cell area.

Note:Some cell spans the area can have row and column index out of the area index.

Parameters:

firstRow - the first row index of the specified cell area

lastRow - the last row index of the specified cell area

firstColumn - the first column index of the specified cell area

lastColumn - the last column index of the specified cell area

Returns:

true if has some cells spans the specified cell area

getCellSpans

Cell[] getCellSpans(int firstRow,
                    int lastRow,
                    int firstColumn,
                    int lastColumn)

Returns the cells that spans the specified cell area. Returns 0 length array if no such cells.

Note:Some cell spans the area can have row and column index out of the area index.

Parameters:

firstRow - the first row index of the specified cell area

lastRow - the last row index of the specified cell area

firstColumn - the first column index of the specified cell area

lastColumn - the last column index of the specified cell area

Returns:

the cells that spans the specified cell area

isSpannedCell

boolean isSpannedCell(Cell c)

Determines whether the cell is spanned cell.

Parameters:

c - the cell

Returns:

true if the cell has merged use the merge(com.zfqjava.swing.cell.Cell).

getSpannedCells

Cell[] getSpannedCells()

Returns all spanned cells.

Returns:

all spannned cells that merged use the merge(com.zfqjava.swing.cell.Cell).

merge

boolean merge(Cell c)

Merges the cell. Returns true if this model changes as a result of the call. (Returns false if this model already contains such spanned cell c or does not permit such operation.)

Parameters:

c - the cell

Returns:

true if this model changed as a result of the call

See Also:

split(com.zfqjava.swing.cell.Cell)

split

boolean split(Cell c)

Splits the cell. Returns true if this model changes as a result of the call. (Returns false if this model have not such spanned cell or does not permit such operation.)

Parameters:

c - the cell

Returns:

true if this model changed as a result of the call

merge(com.zfqjava.swing.cell.Cell)

addCellSpanListener

void addCellSpanListener(CellSpanListener l)

Parameters:

l - the CellSpanListener

removeCellSpanListener

void removeCellSpanListener(CellSpanListener l)

Removes a listener from the list that is notified each time a change to the cell span model occurs.

Parameters:

l - the CellSpanListener
