[QT/C++]Creating objects of class through its name stored in a string?

Question

Can I create an object of a class at runtime, by extracting the class name stored in a string?

eg: I want to create and object of class QButton like

QString strClassName = "QButton";
QButton *pBtn = new strClassName();

I want to read an xml file of all the controls and instantiate them at runtime using this way.

Thanks!

Answer 1

Maybe you are looking for the functionality provided by QUiLoader (http://doc.trolltech.com/4.6/quiloader.html)?

Answer 2

In general, you might want to look at these. As another poster pointed out, this functionality exists in Qt for (at least) Qt classes.
