Where to get QtSigleApplication class

[ashukla]

I included QtSigleApplication, while compiling i am getting

Cannot open include file: 'QtSigleApplication': No such file or directory

it means there is no file named QtSingleApplication in my Qt include directory,

is there any seperate download is required for QtSingleAplication class ,

Still i am using Qt commercial version i don't have QtsingleApplication,

How to get that ?

There is a some problem of include first you search the file with

locate QtSingleApplication

locate QtSingleApplication

To copy to clipboard, switch view to plain text mode 

and then give the absolute path or like this
#include <QtGui/QTextEdit> Search its parent directory. Some times direct include cause problem.
