Where to get QtSigleApplication class

[ashukla]

i am using Qt in windows i searched in QtGui directory there is no such file,

First search qtsingleapplication.h exists or not using with windows Search tool. After that

#include <qtsingleapplication.h>

#include <qtsingleapplication.h>

To copy to clipboard, switch view to plain text mode 

Did you included like this. if not try it. My means is not which you understand. you search the file location and its current parent directory as QTextEdit Exits in QtGui.
