QTimer Lambda

Hello,

I am trying to use the new Lambda method for a static QTimer call.
C++11 is enabled in the .pro file and I am working with Qt 5.5.1.

I am getting a segfault on line 6 when I try to use the following code snipped.
From my understanding this should generally use references to local variables except for the item pointer.
Since I manipulate the item, the lambda function has to use the mutable keyword.

Code:

---

void myWidget::modelItemChanged(QStandardItem *item)
{
    QBrush brush = item->background();
    item->setBackground(Qt::blue);
    QTimer::singleShot(1000, [&, item]() mutable {
        item->setBackground(brush);
    });
}

---

Would appreciate your help.

Your lambda captures "brush" by reference.
"brush" is destroyed when the modelItemChanged() method ends.
The lambda tries to access a destroyed object.

Cheers,

ouch, thats stupid.
