    Question QComboBox inside QTableWidget

    Hi to all
    I've a question;

    I want to be more precise:

    when I select the QComboBox "cell" in my TableWidget
    myTable->currentRow() returns me a 0xffffff value

    Question QTableWidget::currentRow ()

    Hi to all,
    Why in my QTableWidget with a ComboBox cell the function QTableWidget::currentRow () doesn't work ???????

    the function returns the correct int value only if i select the other colums (QTableWidgetItems)

    Thanks in advance

    Well, interacting directly with the combo box does not change the "current" item in the table (unless you do it programmatically).

    For example with an event filter..
    Install this for all cell widgets in you table:
    Qt Code:
    1. bool MyTableWidget::eventFilter(QObject *obj, QEvent *event)
    2. {
    3. if (event->type() == QEvent::FocusIn && obj->isWidgetType())
    4. {
    5. QWidget* widget = qobject_cast<QWidget*>(obj);
    6. if (widget)
    7. {
    8. QTableWidgetItem* item = itemAt(widget->pos());
    9. if (item)
    10. {
    11. setCurrentItem(item);
    12. }
    13. }
    14. }
    15. return QTableWidget::eventFilter(obj, event);
    16. }
    To copy to clipboard, switch view to plain text mode

    Sorry but I haven't understood very well your example

    with this function i can analyze the object (for me is a certain cell ?) and an event, but which is the reason of that return (it's a recursive function ?)

    Sorry for my late answer
    Thanks
    Bye

    Unhandled events are passed to the base class's eventFilter() function, since the base class might have reimplemented eventFilter() for its own internal purposes.
