@Koljasha
Heh ok then flat win 10 style is pretty not exciting :)

Hmm that is a bit odd.

What was the version you upgraded from ?

@mrjj today I download Qt 5.7.1 for Linux 64-bit (729 MB)
It's free install. Now Qt 5.7.1, QtCreator 4.2
Earlier was 5.7.0

@mrjj I used to so never encountered ...
and today was puzzled :-)

mrjj · 15 Dec 2016, 12:48

Oh
So it changed between 5.7.0 and 5.7.1 ?

Koljasha · 15 Dec 2016, 12:59

@mrjj yes!
maybe it's just me ...

@Koljasha
Maybe the .user file was damaged
and the setting did not really work.
Before you reset it.

@mrjj I specifically removed ~/.config/QtProject
still must disable/enable "Run in terminal"
work at least now there is a solution on the forum :-)

@Koljasha
Hi
in the project folder
there is a .user file
same name as the .pro
Did u try delete that?
(not sure it does anything. just to check)

Koljasha · 15 Dec 2016, 13:22

@mrjj No...
It is not work. I delete .user file....
It's something in new Qt ot QtCreator.... and maybe only in Linux...
Tomorrow I will try to install on Windows, and then write ...

@Koljasha
Yes it could be as its different on win / linux with the "console"
Good test :)

@mrjj Hello!
I try on two my PC with Windows 10 (home and work). And everywhere I must recheck (turn off/on) "Run in terminal". It's bug in new version.

@Koljasha
Ok. let me see if i get bug when upgrading. :)

Koljasha · 29 Oct 2021, 01:46

@mrjj OK.
It is very interesting. I use clean installation on Ubuntu and Windows.
And for exemple free C++ project and free Qt console project.
In C++: cout << "Hello" << endl;
In Qt: qDebug() << "Hello";

@mrjj hi I have the same problem, too
It seems that qt creator didn't write the "run in terminal" option
<value type="bool" key="Qt4ProjectManager.Qt4RunConfiguration.UseTerminal">true</value>
in the pro.user file after the project created by the wizard

the "UseTerminal" line above will be writed into the pro.user file only if I manually uncheck and check this option in the project setting .

I tried to find a config file of Qt4Project in the qtcreator to correct its behavior but failed,.
Could you please give me some advice to fix this problem?
Thanks in advance.

@raymanT
Does sounds the same. Flip flopping the settings makes it save it.
I upgraded via maintenance tool but here the settings does seems to work.

raymanT · 23 Dec 2016, 08:53

@mrjj
Hello
I just found that if using Qbs I will not encounter this problem, maybe it is the problem of qt4projectmanager, now I just use Qbs in my project for workaround.

@raymanT
Ok. If it is a bug it most likely get fixed in next release. I have not
tried yet to fully reproduce it. Seems not to happen every time.

@Koljasha Hi, I got a doubt related to console output. I suppose the console output appears in the compile output section of the Qt Creator. Please confirm.

Suppose , In Qt , QString myQuote= "Hello";
Can I write qDebug()<< myQuote to get Hello in my console output?

Thanks !
