Use QThread in qt-3.1

Message 1 in thread

hi,

Good morining.


I want to use Qthread in my .ui.h  file like as follows,


class GuiThread:public QThread
{
public:

 void run()
 {


 }



};


When compiled the project with QT_THREAD_SUPPORT, it will me error like

/usr/lib/qt-3.1/include/qthread.h:60: parse error before `void'


What's the problem???




Thanks and Regards,
Niranjan

What's exactly in line 60? I don't have Qt 3.1 available right now.

Are you using qmake and *.pro files? If so, add to the *.pro file:
	CONFIG += thread

It appears you want to use this new thread class for GUI things. Be 
careful with that, in Qt most GUI elements can be accessed from only 
from one thread - the thread that runs the event loop.
