Why when running .exe file has 2 windows pop up

DQUY05

Hi,

I run the application for desktop, when I run it on Qt IDE, there is no problem, but when I run the .exe file directly (or build with inno to run on another computer), two windows appear, I don't know what is this black window (win1),
While my other apps are normal
Please help everyone

Many thanks !

Looks like you have CONFIG += console in your pro file

Dear Sir,

This is my .pro file, absolutely no CONFIG += console

Thanks !

QZXing.pri

Maybe in there.

You can remove a config option with

CONFIG -= debug

Add this just before your SOURCES +=

Thank Sir !

I don't speak English well, am I doing this right, it still doesn't work

QT += core gui
QT += testlib
QT += multimedia multimediawidgets
QT += printsupport

CONFIG += staticlib
CONFIG += qzxing_qml
CONFIG += qzxing_multimedia
CONFIG -= debug
include(QZxing-master/src/QZXing.pri)

@DQUY05 As I already said maybe CONFG += console is added in QZXing.pri, so removing it before including the pri-file will not help at all...

@Christian-Ehrlicher

Dear Sir,

Even if I don't use QZXing, the error is still the same
Could it be due to another reason?

Thanks !

#CONFIG += staticlib
#CONFIG += qzxing_qml
#CONFIG += qzxing_multimedia

Hi, if you build it for Release (not Debug) do you still get 2 windows?

DQUY05

@hskoglund

Yes Sir,

That's probably because that QT += testlib
Qt test should only be used in unit testing, not in real application.

@Bonnie
Thank Sir,

indeed it was caused by QT += testlib, I'm glad the problem is solved
