[Qt-interest] What is the Use of QPlugin Loader

[Malyushytsky, Alex]

I am not sure I understand the question.
I believe http://doc.qt.nokia.com/latest/qpluginloader.html
is clear :

"The QPluginLoader class loads a plugin at run-time"

...A Qt plugin is stored in a shared library (a DLL) and offers these benefits over shared libraries accessed using QLibrary<http://doc.qt.nokia.com/latest/qlibrary.html>:

 *   QPluginLoader checks that a plugin is linked against the same version of Qt as the application.
 *   QPluginLoader provides direct access to a root component object (instance<http://doc.qt.nokia.com/latest/qpluginloader.html#instance>()), instead of forcing you to resolve a C function manually."

Hi All,
I want to know why QPluginLoader is used.
For what purpose we use QPluginLoader.
QLibrary is mainly used to resolve symbols. But i dono y QPluginLoader mainly used for.
instance() method in QPluginLoader  returns QObject Pointer.

I need some idea.
