JSpinner Update
I creates a dataTable and cellEditor form one column. This column is simple jSpinner. I have the following problem. When I enter some value in the spinner and select the another row, the value in the previous row won't be changed. If I press , it'll done. If I select or button, it will done too. But if I enter value and change selection, it won't be done. Help, please. Here is the CellEditor code.
public class DurationTableCellEditor extends AbstractCellEditor implements TableCellEditor{
final JSpinner spinner = new JSpinner();
// Initializes the spinner.
public DurationTableCellEditor() {
spinner.setModel(new SpinnerNumberModel(1,1,50000,1));
}
// Prepares the spinner component and returns it.
public Component getTableCellEditorComponent(JTable table, Object value,
boolean isSelected, int row, int column) {
spinner.setValue(new Integer(value.toString()).intValue());
spinner.setCursor(null);
return spinner;
}
// Enables the editor only for double-clicks.
@Override
public boolean isCellEditable(EventObject evt) {
if (evt instanceof MouseEvent) {
return ((MouseEvent)evt).getClickCount() >= 1;
}
return true;
}
// Returns the spinners current value.
public Object getCellEditorValue() {
return spinn开发者_JAVA技巧er.getValue();
}
}
It's not clear how you're updating your data model, but one approach would be to implement ChangeListener
in your CellEditor
, much as this example implements ItemListener
. For reference, see How to Use Tables: Using Other Editors. In particular, look at fireEditingStopped()
. Finally, you'll need a corresponding TableCellRenderer
.
do commitEdit()
// Returns the spinners current value.
public Object getCellEditorValue() {
spinner.commitEdit();
return spinner.getValue();
}
