How to use the new QtCreator for console input/output?

[Koljasha]

Hello!

Sorry for my english, I am using a translator!

Today updated Qt. Now Qt 5.7.1, QtCreator 4.2
I can not understand how to use it is now :-)

A simple console application in pure C++.
Previously, when I run the application appeared a separate console. In it I had stdin (cin >>) and stdout (cout <<).
Now stdout is written directly into QtCreator box below. And how to use stdin I can not understand (((

Hi
Can you try this ?

Click "Run in terminal" to ON

[Koljasha]

@mrjj Great thank you!!!!
In the new version a bit redesigned, but the problem is solved in this way !!!

Hi
Yes there are many new things :)

Also note if using on win 10, there is new flat look to match win 10.

"Sorry for my english, I am using a translator!"
Seems to work pretty well :)

@mrjj I use Ubuntu :-)
and about "Run in terminal" - maybe it's a bug in my.
"Run in terminal" enabled by default, but it does not work. I have to turn off / on and then works properly. In previous versions, this was not ...

@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 ?

[Koljasha]

@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

[Koljasha]

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

[mrjj]

Oh
So it changed between 5.7.0 and 5.7.1 ?

[Koljasha]

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

[mrjj]

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

[Koljasha]

@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]

@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 ...

[mrjj]

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

[Koljasha]

@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.

[mrjj]

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

[Koljasha]

@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.

[mrjj]

@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.

@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.
