Determining class of icon in Draggable Icons example

In the Draggable Icons examples, there is a mouse press event with this code:

Code:

---

void DragWidget::mousePressEvent(QMouseEvent *event)
 {
     QLabel *child = static_cast<QLabel*>(childAt(event->pos()));
     ...
 }

---

How would I change it so that I can determine what class the object childAt(event->pos()) is? I looked at the QWidget documentation, and I couldn't find a function similar to something like getClass() or getObjectType(). Any help would be appreciated.

I don't find anything either... what about setting a objectName (QObject property) each time you create a QWidget, or maybe setAccessibleDescription with the type?

Hi, if you have a limited number of possible classes, you can use QObject::qobject_cast for this. It returns zero if childAt(event->pos()) is not of the type you tried to cast it to.

please do not an set object name.

Ask the childAt for its metaObject. It should answer all your question. There is className, inherits and so in the metaObject.
