[Qt-interest] QWidget: Must construct a QApplication before a QPaintDevice

[Santhosh Y]

Hi,

I am facing a problem saying "QWidget: Must construct a QApplication 
before a QPaintDevice",
when I am invoking a GUI-application (which is in .dll form) in my 
application.

======================================
Scenario is as follows:
======================================
- I developed a  GUI application using Qt (my first application)
- In the development of second application, I integrated my first 
application as a DLL in to the second application
- I launched the second application as we usually do. (QApplication 
creation ...). I am able to show all GUI widgets
       specific to my second application.
- When I am trying to invoke my first application, from second 
application, it is showing the message
     "QWidget: Must construct a QApplication before a QPaintDevice" and 
exiting from that point.


Can anyone suggest me what is wrong here?
