Class TableModelFormat

java.lang.Object
  diamondedge.swing.grid.TableModelFormat

All Implemented Interfaces:

TableFormat, EventListener, TableModelListener

public class TableModelFormat
extends Object
implements TableFormat, TableModelListener

This class allows a mapping to be specified between the actual data value in the cell and a set of values. The actual value in the grid will correspond to the value in the TableModel for the selected row and the BoundColumn. The value displayed in the grid will correspond to the value in the TableModel for the selected row and the TextColumn. When editing in a DsGrid, a multi-column drop-down ComboBox will be used as the editor.

int	getTextColumn() Determines the column used as the value for the Text.
Object	getTextValue(int row) Returns the value for the display column at specified row.
Object	getValueAt(int rowIndex, int columnIndex) Returns the value for the cell at columnIndex and rowIndex.
boolean	isBoundColumnVisible() Determines whether the column used as the data value is visible.
void	loadTextData(Reader reader, int begRow, int begCol, int endRow, int endCol, boolean firstRowIsColHeader, char delim, boolean stripStringDelim, boolean convertData) Load data from a text stream.
void	setBoundColumn(int val) Determines the column used as the data value.
void	setBoundColumnVisible(boolean showBoundColumn) Determines whether the column used as the data value is visible.
void	setModel(TableModel dataModel) Sets the TableModel used to supply all data values.
void	setTextColumn(int val) Determines the column used as the value for the Text property which is diplayed in the text area of the ComboBox.
void	setValueAt(Object aValue, int rowIndex, int columnIndex) Sets the value in the cell at columnIndex and rowIndex to aValue.

TableModelFormat

public TableModelFormat()

Method Detail

getModel

public TableModel getModel()

Returns the TableModel used to supply all data values.

setModel

public void setModel(TableModel dataModel)

Sets the TableModel used to supply all data values.

loadTextData

public void loadTextData(Reader reader,
                         int begRow,
                         int begCol,
                         int endRow,
                         int endCol,
                         boolean firstRowIsColHeader,
                         char delim,
                         boolean stripStringDelim,
                         boolean convertData)
                  throws IOException,
                         ArrayIndexOutOfBoundsException

Load data from a text stream. The TableModel must have enough rows and columns to load the data or an exception will be thrown.

Parameters:

reader - stream that provides the data

begRow - row position in model to begin placing data

begCol - column position in model to begin placing data

endRow - ending row position in model to stop setting data. -1 means to load all data.

endCol - ending column position in model to stop setting data. -1 means to load all columns up to model.getColumnCount.

firstRowIsColHeader - the first row is used to set the column headers

delim - delimeter used to separate values. Pass in '\t' for tab delimeted and ',' for csv.

stripStringDelim - removes the " at the beginning and end of strings

convertData - attempt to parse the values into a Number, Boolean, Date in that order

Throws:

IOException

ArrayIndexOutOfBoundsException
