我有一个 TableView,它使用 ColorPicker 来(显示/编辑)单元格中的颜色。该表在所需字段中显示颜色选择器,但编辑不起作用。
TableColumn<SeriesPreferences, Color> c2 = new TableColumn<SeriesPreferences, Color>("Color");
c2.setCellValueFactory(new PropertyValueFactory<SeriesPreferences, Color>("color"));
c2.setCellFactory(new Callback<TableColumn<SeriesPreferences, Color>,
TableCell<SeriesPreferences, Color>>()
{
@Override
public TableCell<SeriesPreferences, Color>
call(final TableColumn<SeriesPreferences, Color> param)
{
TableCell<SeriesPreferences, Color> cell =
new TableCell<SeriesPreferences, Color>()
{
@Override
public void updateItem(Color c, boolean empty)
{
if(c != null)
{
final ColorPicker cp = new ColorPicker();
cp.setValue(c);
setGraphic(cp);
cp.setOnAction(new EventHandler<javafx.event.ActionEvent>()
{
public void
handle(javafx.event.ActionEvent t)
{
getTableView().edit(getTableRow().getIndex(), param);
commitEdit(cp.getValue());
}
});
}
}
};
return cell;
}
});
c2.setOnEditCommit(new EventHandler<CellEditEvent<SeriesPreferences, Color>>()
{
@Override
public void handle(CellEditEvent<SeriesPreferences, Color> t)
{
((SeriesPreferences) t.getTableView().getItems().get(t.getTablePosition().
getRow())).setColor(t.getNewValue());
}
});
当我更改颜色选择器中的颜色时,没有调用编辑事件处理程序,有什么想法吗?
