Method Detail

addEventListener

void addEventListener(IstiEventListener l)

Adds a listener to the list that's notified each time a change to the data model occurs.

Parameters:

l - the listener.

getColumnCount

int getColumnCount()

Returns the number of columns in the model.

Returns:

the number of columns in the model

See Also:

getRowCount()

getColumnName

java.lang.String getColumnName(int columnIndex)

Returns the name of the column at columnIndex. This is used to initialize the table's column header name. Note: this name does not need to be unique; two columns in a table can have the same name.

Parameters:

columnIndex - the index of the column

Returns:

the name of the column

getRowCount

int getRowCount()

Returns the number of rows in the model. A table uses this method to determine how many rows it should display. This method should be quick, as it is called frequently during rendering.

Returns:

the number of rows in the model

getValueAt

java.lang.Object getValueAt(int rowIndex,
                            int columnIndex)

Returns the value for the cell at columnIndex and rowIndex.

Parameters:

rowIndex - the row whose value is to be queried

columnIndex - the column whose value is to be queried

Returns:

the value Object at the specified cell

isCellEditable

boolean isCellEditable(int rowIndex,
                       int columnIndex)

Returns true if the cell at rowIndex and columnIndex is editable. Otherwise, setValueAt on the cell will not change the value of that cell.

Parameters:

rowIndex - the row whose value to be queried

columnIndex - the column whose value to be queried

Returns:

true if the cell is editable

See Also:

setValueAt(java.lang.Object, int, int)

setValueAt

void setValueAt(java.lang.Object aValue,
                int rowIndex,
                int columnIndex)

Sets the value in the cell at columnIndex and rowIndex to aValue.

Parameters:

aValue - the new value

rowIndex - the row whose value is to be changed

columnIndex - the column whose value is to be changed
