Qt application removes CMD when it runs independently

Qt_crazyer

After packing programs in release mode, every running program always opens the Windows console before the display of my program. How should I close the console？
I learned that this might be related to my use of testlib. Because in my application, I call

QTest:: qWait ();

I don't know how to correctly modify the pro file, here is it:

QT       += core gui
QT       += testlib
QT       += multimedia

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = iass
TEMPLATE = app

DEFINES += QT_DEPRECATED_WARNINGS
DEFINES += QT_MESSAGELOGCONTEXT

CONFIG += mobility

RESOURCES += \
    image.qrc

RC_ICONS = Password.ico

SOURCES += \
        main.cpp \
        mainwindow.cpp
HEADERS += \
        mainwindow.h

Qt Creator 5.9.1 on windows10
MSVC2015 64bit complier
Thanks for any advice.

Hi
well you have template = app
so it seems not to be a console app.
QTest:: qWait () is for unit testing. (normally)

What do you need qWait for ?

Qt_crazyer

@mrjj
My application is a Qt Widgets Application.
I use the qWait just for a delay of time. I don't know much about unit testing.

mrjj

@Qt_crazyer
But have you tested that removing qWait() also removes the
console window?

@Qt_crazyer Remove

QT       += testlib

mrjj

@jsulm
and then also QTest:: qWait () , i assume ? or ?

jsulm

@mrjj Yes, there are better ways to wait (if you really want to) :-)

mrjj

@jsulm
100% agree. :)
Well QThread::wait wont work the same so i guess some refactoring is needed to
work again without QTest

I rewrote a function with QTimer for a delay of time. Remove the testlib. Now it works well, without the console.
Thanks you.

@Qt_crazyer said in Qt application removes CMD when it runs independently:

and by the way, a timer is much better than a delay :)
