Questions on JTable

[Walter Tang]

Hello everyone,

When I display the data from database, how can I discard the previous display in JTable. Because, when I do the search the second time, the results are appended to the previous results. That makes user really confused on the table. I hope I describe my problem acurately. Thanks a billion for your help

It depends on your table model class (I assume you have one).

You can create a new table model for your new data and then re-register it with the view JTable.setModel(myTableModel)

Or better,

you can write or use an existing setData type method that replaces the models collection of records, then fire a AbstractTableModel.fireDataChanged or whatever it's called.

Hi,
You could also try TableModel.setDataVector()?

Hi,Walter

If you want to use AbstractTableModel .All methods in the interface must be implemented.
Usually,you need to provide three methods:

public int getRowCount();  
public int getColumnCount();
public int getValueAt(int row,int column);

You have still second selection - consider to use DefaultTableModel.

Hi Walter,

You can also use the TableModel interface. Can have more customization.
