Muhtemelen belirli örnekler için .pro dosyalarını açarak tüm qt demolarını çalıştırmak / oluşturmak isteyeceksiniz.

Qtcreator içinde textures.pro dosyasını açarak opengl / textures örneğini oluşturmaya gittiğimde, projeyi otomatik olarak yapılandırdı, ancak varsayılan olarak QT4'e işaret ediyordu. Ben qt4 kullanarak inşa etmeye çalışırken QtWidgets bulamadığını söyledi garip bir hata var. Derleme aracı olarak Qt5 ile sorun ortadan kalktı.
Qtcreator'da varsayılan olmadığından, hata ayıklama / serbest bırakma için proje derlemesi olarak QT5'e NOKTADAN emin olun. Aksi takdirde bina yaparken garip hatalar alırsınız. Bu sorun, qt5 include ve qt5 libs yollarını göstermesi gereken derleme çıktısında kolayca belirlenebilir.
