how to avoid command prompt while reunning EXE ?

Hi all,

I created GUI Application Exe . If I run the exe . One command prompt is comming with

this in Windows. How to avoid this Command prompt window ?

If you are using MinGW then refer to

I am using VS compiler

Do you use a .pro file? If so, remove CONFIG+=console from it. If not, access your Qt VS integration module and disable the console there.

I am using cmake to compile my application .

Then read cmake ml or documentation :)

I added WIN32 in ADD_EXECUTABLE of CMake


But I am getting the following error,


error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup


:)

Did you forgot to add QT_QTMAIN_LIBRARY to target_link_libraries ?

Make clean (or at least delete main.o) and rebuild. Sources haven't changed so you need to force a rebuild by hand.

I did clean and then build ,still i am getting same error.

I am suspecting my main implementation,

i am using main like below,

Code:

---

int main(int argc,char* argv[])
{
                QApplication myApp(argc,argv);
 
	MyMainWindow mainWnd;
 
	mainWnd.show();
 
	return myApp.exec();
}

---

MyMainWindow is derived from QMainWindow.

Is my main implementation correct ?

Yes, it's fine. Your project file has to be incorrect.

Now I solved by adding following Lines in the CMakeLists.txt File.

IF(WIN32)
LINK_LIBRARIES(
${QT_QTMAIN_LIBRARY}
)
ENDIF(WIN32)

IF(WIN32)
ADD_DEFINITIONS(-DQT_DLL)
ENDIF(WIN32)


and then ,

WIN32 in ADD_EXUCUTABLE

No need to add this for WIN32 only. ${QT_QTMAIN_LIBRARY} is just empty on linux and QT_DLL is ignored (why do you need it at all?)
