      com.jidesoft.grid.RowHeightChangeEvent

All Implemented Interfaces:

Serializable

public class RowHeightChangeEvent
extends EventObject

RowHeightChangeEvent is used to notify listeners that a table's row height has changed. Depending on the parameters used in the constructors, the RowHeightChangeEvent can be used to specify the following types of changes:

 RowHeightChangeEvent(source);              //  The data, i.e. all rows height changed
 RowHeightChangeEvent(source, 1);           //  Row 1 height changed
 RowHeightChangeEvent(source, 3, 6);        //  Rows 3 to 6 inclusive changed
 RowHeightChangeEvent(source, 3, 6, INSERT); // Rows (3, 6) were inserted
 RowHeightChangeEvent(source, 3, 6, DELETE); // Rows (3, 6) were deleted

source

Constructor Summary

RowHeightChangeEvent(RowHeights source)
All row data in the table has changed, listeners should discard any state that was based on the rows and re-query the RowHeights to get the new row count and all the appropriate values.

RowHeightChangeEvent(RowHeights source, int row)
This row of data has been updated.

RowHeightChangeEvent(RowHeights source, int firstRow, int lastRow)
The data in rows [firstRow, lastRow] have been updated.

RowHeightChangeEvent(RowHeights source, int firstRow, int lastRow, int type)
The cells from (firstRow, column) to (lastRow, column) have been changed.

Method Summary

int	getFirstRow() Returns the first row that is changed.
int	getLastRow() Returns the last row that changed.
int	getType() Returns the type of event - one of: INSERT, UPDATE and DELETE.

Constructor Detail

RowHeightChangeEvent

public RowHeightChangeEvent(RowHeights source)

All row data in the table has changed, listeners should discard any state that was based on the rows and re-query the RowHeights to get the new row count and all the appropriate values. The JTable will repaint the entire visible region on receiving this event, querying the model for the cell values that are visible. The structure of the table, i.e. the column names, types and order have not changed.

Parameters:

source - the source for the event.

RowHeightChangeEvent

public RowHeightChangeEvent(RowHeights source,
                            int row)

This row of data has been updated. To denote the arrival of a completely new table with a different structure use HEADER_ROW as the value for the row. When the JTable receives this event and its autoCreateColumnsFromModel flag is set it discards any TableColumns that it had and reallocates default ones in the order they appear in the model. This is the same as calling setModel(RowHeights) on the JTable.

Parameters:

source - the source for the event.

row - the row index.

RowHeightChangeEvent

public RowHeightChangeEvent(RowHeights source,
                            int firstRow,
                            int lastRow)

The data in rows [firstRow, lastRow] have been updated.

Parameters:

source - the source for the event.

firstRow - the first row index.

lastRow - the last row index.

RowHeightChangeEvent

public RowHeightChangeEvent(RowHeights source,
                            int firstRow,
                            int lastRow,
                            int type)

The cells from (firstRow, column) to (lastRow, column) have been changed. The column refers to the column index of the cell in the model's co-ordinate system. When column is ALL_COLUMNS, all cells in the specified range of rows are considered changed.

The type should be one of: INSERT, UPDATE and DELETE.

Parameters:

source - the source for the event.

firstRow - the first row index.

lastRow - the last row index.

type - the event type.

Returns the last row that changed.

Returns:

the last row that is changed.

getType

public int getType()

Returns the type of event - one of: INSERT, UPDATE and DELETE.
