QDateEdit in QTableWidget

[ceddy]

With the following code Put a DateEdit in a Cell of a TableWidget:

QDateEdit *dateEdit = new QDateEdit();
    dateEdit->setDate(QDate::currentDate());
    ui->twHomeworkList->setCellWidget(ui->twHomeworkList->rowCount()-1,1,dateEdit);

QDateEdit *dateEdit = new QDateEdit();
    dateEdit->setDate(QDate::currentDate());
    ui->twHomeworkList->setCellWidget(ui->twHomeworkList->rowCount()-1,1,dateEdit);

To copy to clipboard, switch view to plain text mode 

Now I tied to read the Date fromt the Edit:

QString x= static_cast<QDateEdit*>(ui->twHomeworkList->cellWidget(1,y))->date().toString();

QString x= static_cast<QDateEdit*>(ui->twHomeworkList->cellWidget(1,y))->date().toString();

To copy to clipboard, switch view to plain text mode 

But the application just crash.
Can somebody help me?

You need some more parentheses, something like :

QString x = (static_cast<QDateEdit*>(ui->twHomeworkList->cellWidget(1,y)) )->date().toString();

QString x = (static_cast<QDateEdit*>(ui->twHomeworkList->cellWidget(1,y)) )->date().toString();

To copy to clipboard, switch view to plain text mode 

That is because you need to cast what is returned by cellWidget(...) and then call the date() function from a QDateEdit pointer.

//you are safer if you use dynamic_cast first, check to be different then null and only then call functions using the pointer, static_cast should be faster, but you need to be absolutely sure that it doesn't fail

LE: Forget the parenthesis - it should work as you write it... debug your code and make sure that you access and cast the correct coordinates (1, y) that hold the QDateEdit.

Also dynamic_cast with check for returded null pointer is safer.

Thanks for the answer, but it doesn't changed anything

Yes, see the "later edit"

One issue is that you insert DateEdit on last row, and when you try to access it you always get the "QWidget*" from the first row //and the cast fails

Sorry doesn't mind that
