Problem with KeyPress event and QTableView

[ranna]

Hi,

I have an issue with moving next cell in a QTableView by pressing Key_Return. In some cases like a cell has dropdown list box as its item and from that cell if i press Enter/Return key it throws a exception while exetuing this->setCurrentIndex(Index).

this refers to a object of QTableView
and Index refers to a QModelIndex.

The exception is

ASSERT: "VisualRow != -1" in file itemviews\qtableview.cpp line 932. (I am using Qt 4.4).

sample code segment

{
    const QModelIndex& Index = this->moveCursor(QAbstractItemView::MoveNext, Qt::KeypadModifier);
    if(Index.isValid())
        this->setCurrentIndex(Index);
}

{
    const QModelIndex& Index = this->moveCursor(QAbstractItemView::MoveNext, Qt::KeypadModifier);
    if(Index.isValid())
        this->setCurrentIndex(Index);
}

To copy to clipboard, switch view to plain text mode 

the problem only occurs if the current cell itself has a ComboBox or other QWidgets

Please share your ideas to solve ths issue.

The assert you're referring to is actually in QTableView::moveCursor(). Anyway, could you provide a minimal compilable example that reproduces the problem?
