Something in Qt broke and I can't compile anymore. QVBoxLayout doesn't name a type. [solved]
-
The problem is - everything was working fine, then I changed QVBoxLayout to QGridLayout after that if I include <QGridLayout> or any other Layout related stuff I get this kind of errors (they appear in projects that were builing just fine before)

Thanks for response.

You are probably just missing:@QT += widgets@
in your pro file.

Nope, just checked to be sure. It's even appears on freshly created QtWidget program, as soon as you write #include <SomethingRelatedToLayout> somewhere. And it compiles on my notebook just fine. (and compiled before "something" happened to Qt/Creator). -
Can you check that the header hasn't been modified accidentally ?

In mingw48_32\include\QtWidgets all headers haven't been modified since installation. I guess I'll have to reinstall my Qt. I want to know what caused this sort of behavior, though. -
Search/Replace on the wrong set of files, gremlins… There's a lot of possibilities

Probably gremlins. Haven't touched any of qt files.
Was just playing around in simple test widget project. Decided to change VBox to Grid and that happened. -
You might have had one or more of Qt's header file opened and did a search/replace on all opened documents and bam, there's your gremlins playing hell on your setup

Is where a way to fix it without re-downloading all of the Qt?

You can try downloading only the sources, and replace the headers with those from the sources

Thanks. That helped. -
You're welcome !
If you have everything working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)
