JTable combobox editor

[awvvo]

I have a JTable with 17 columns. The last 15 columns contain airport
codes (this is used
for entering a flight schedule). The application uses a list of 5000
airport codes.

When I do:
column.setCellEditor(new MyComboBoxEditor(airportValues));

for each column it is very slow.

Is it possible to only use 1 combobox and reuse and activate it as a
celleditor when I click on a particular cell?

Can someone give me a hint how to do this?

regards
john

You could build a static JComboBox, populate it, and just add/remove
it as needed.

I assume MyComboBoxEditor extends TableCellEditor?

Subclass the JTable and override the TableCellEditor getCellEditor(int
row, int column) method. Like this:

public class MyJTable extends JTable
{
private MyComboBoxEditor comboEditor =
new MyComboBoxEditor(airportValues);

// ...

public TableCellEditor getCellEditor(int row, int column)
{
if(column > 2)
{
// if necessary, change the comboEditor values
return comboEditor;
}

return super.getTableCellEditor(row, column);
}
}

Customize to suit your needs.
