Method Detail

getInstance

public static BulletinBoard getInstance()
Get the BulletinBoard model instance.

Returns:
singleton BulletinBoard

showBulletinBoard

public static void showBulletinBoard()
Display the BulletinBoard window.


aprsMessageReceived

public void aprsMessageReceived(Message msg)
Process the next message received by YAAC that is an APRS message.

Specified by:
aprsMessageReceived in interface AprsMessageListener
Parameters:
msg - some subclass of Message containing the message contents; the message should have an AX25Frame connected to it
See Also:
AX25Frame, AX25Message.ax25Frame, AX25Message.getAx25Frame()

getRowCount

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

Specified by:
getRowCount in interface javax.swing.table.TableModel
Returns:
the number of rows in the model
See Also:
getColumnCount()

getColumnCount

public int getColumnCount()
Returns the number of columns in the model.

Specified by:
getColumnCount in interface javax.swing.table.TableModel
Returns:
the number of columns in the model
See Also:
getRowCount()

getColumnName

public java.lang.String getColumnName(int column)
Returns the localized name for the column.

Specified by:
getColumnName in interface javax.swing.table.TableModel
Overrides:
getColumnName in class javax.swing.table.AbstractTableModel
Parameters:
column - the column being queried
Returns:
a string containing the name of column

getColumnClass

public java.lang.Class<?> getColumnClass(int columnIndex)
Returns the data Class for the specified column.

Specified by:
getColumnClass in interface javax.swing.table.TableModel
Overrides:
getColumnClass in class javax.swing.table.AbstractTableModel
Parameters:
columnIndex - the column being queried
Returns:
the Class object for the column's data

isCellEditable

public boolean isCellEditable(int rowIndex,
                              int columnIndex)
Specified by:
isCellEditable in interface javax.swing.table.TableModel
Overrides:
isCellEditable in class javax.swing.table.AbstractTableModel

getValueAt

public java.lang.Object getValueAt(int rowIndex,
                                   int columnIndex)
Returns the value for the cell at columnIndex and rowIndex.

Specified by:
getValueAt in interface javax.swing.table.TableModel
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

getColumnWidth

public int getColumnWidth(int columnIndex)
Specifies the default initial width of a column from this model. Should only be queried at table creation time.

Specified by:
getColumnWidth in interface ColumnSizingTableModel
Parameters:
columnIndex - int index of the model's column whose width should be obtained
Returns:
the width, in the same units used by the TableColumn class's setWidth() method, or -1 to indicate the width should not be forced

isSizeToFit

public boolean isSizeToFit(int columnIndex)
Specifies whether setWidthToFit() should be enabled on this column

Specified by:
isSizeToFit in interface ColumnSizingTableModel
Parameters:
columnIndex - int index of the model's column whose width should be obtained
Returns:
boolean true if sizeWidthToFit() should be called on this column

compareRows

public int compareRows(int rowIndex1,
                       int rowIndex2,
                       int columnIndex)
Compare the selected column of the two rows.

Specified by:
compareRows in interface FastComparableTableModel
Parameters:
rowIndex1 - zero-based model row index of first row to compare
rowIndex2 - zero-based model row index of second row to compare
columnIndex - zero-based model column index of column to compare
Returns:
+1 if the 1st row's column is after the 2nd row's column, -1 if before, or 0 if equal precedence

fontChanged

public void fontChanged(java.lang.String category,
                        java.awt.Font newFont)
