Constructor Detail

DefaultTableViewModel

public DefaultTableViewModel()

constructs a empty table data model

DefaultTableViewModel

public DefaultTableViewModel(Vector columnNames)

constructs a DefaultTableViewModel without table data, only columnNames

Parameters:

columnNames - the vector which contains the columnNames

DefaultTableViewModel

public DefaultTableViewModel(Vector data,
                             Vector columnNames)

constructs a table data model with the data vector and the column names

Parameters:

data - the vector which contains the data

columnNames - the vector which contains the columnNames

DefaultTableViewModel

public DefaultTableViewModel(Vector data,
                             Vector columnNames,
                             boolean columnAutoCreated)

constructs a table model with the data as a Vector and columnnames as a Vector. with the third boolean parameter columnAutoCreated, you can determine if the visible columns (for display) should be automatically created or not. If columnAutoCreated=true, all the available columns will be showed in the table. To hide a column, use the method @see #removeColumn(String columnKey). If the parameter columnAutoCreated = false, there will be no visible columns automatically created. To show a column, pls use the method @see #addColumn(String columnKey)

Parameters:

data - the vector which contains the data

columnNames - the vector which contains the columnNames

columnAutoCreated - a boolean variable which determins if the visible columns should be automatically created or not.
