Hi, and welcome! @Akash-Shanmugaraj said in Application Output not Visible in Qt Design Studio: I accidentally clicked some button which disabled the Application Output (for designing app) completely. Your Application Output pane is right there in the middle of your screenshot. It's the other panes that have been hidden. You can bring them back by clicking View > Views > Form Editor, for example.

@Kyeiv OK, but please put the error checking code in anyway. With OS commands you never know what might go wrong (just like you discovered), so it's important to check for & report all errors! And especially if you are going to be distributing this....

These messages aren't critical, you can ignore them. What's important is, that you don't crash the application anymore.

Hello from the future. 5 years later and still not a feature, but here's a ugly workaround I have been using to some degree of satisfaction: On the main Qt Creator window: pull up the bottom panel divider all the way up covering as much of the window as possible select <no document> open a new window(s) form the "split" icon, and use that as the main editor window This way, I have a window just for the output separated from the code editing. Anyway, not pretty, but gets the job done.

Hi, Might be a bit of short answer but… AFAIK, no you can't.

@BluTiGeS I'm using http://funq.readthedocs.org/ for something similar.

@kolegs Thanks a lot dear kolegs. Very good reply ;)

Hi @AnantAgrawal, Just just launch your app from the console. qDebug, qWarning etc. will be printed to the console too (stdout/stderr). Make sure you don't define QT_NO_DEBUG_OUTPUT -- see http://doc.qt.io/qt-5/debug.html for more info.
