No qwt objects in UI designer on Windows

**Khaine** · 22nd March 2016, 17:19

I just recently compiled and installed qwt in my QtCreator. I can compile and run examples provided in package, so I assume that it's probably installed correctly. Unfortunately there are no qwt objects in UI designer. I have CONFIG += qwt in .pro file of course. What did I miss?

Form editor says, that it's "It is not a valid win32 application".

Did you read: http://qwt.sourceforge.net/qwtinstall.html#USEPLUGIN

The problem was with compilation. I have no idea why, but I had to completely recompile qwt from a scratch again and suddenly designer plugin started to work.
