Just include the header as

Code:

---

#include <QtSingleApplication>

---

and use it. Why do you want to find it source code. In Unix you can locate any file using with locate <filename> command. After building the Qt; all the src code deleted. So, you should search on fresh copy for it to extract the source code of it.

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 ?

The QtSingleApplication component is available to customers only and can be downloaded from here: http://trolltech.com/products/qt/add...leapplication/

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

Code:

---

locate QtSingleApplication

---

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

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

Code:

---

#include <qtsingleapplication.h>

---

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.

Guys, how hard it is to read one post?
QtSingleApplication is NOT in the commercial Qt distribution. It has to be downloaded separately from the URL I posted earlier.

Yes! I am saying same thing. You can search in a system for that file if not exists; then load from as you have specified earlier.

If he didn't download it, how could it exist? Solutions are a separate component series for each you have to pay separately.

ok thank you for your information.

From your post i am understanding there is different download for QtSingleApplication.

if i am wrong correct me.

How to order for this ?

Take a look at post #4 in this thread.
