Re: [Interest] QFile::write(const QByteArray&) does not write all data?

Are you sure your QByteArray has the correct size? If your constructed it from a const char* and did not give the size, it may contain only data up to the first zero byte. helmut -Ursprüngliche Nachricht- Von: Interest [mailto:interest-bounces+helmut.muelner=gmail@qt-project.org] Im

[Interest] Qt3D, QtQuick, Windows 10, VS-2017 64 bit, Qt-5.10.0: Program not working

Hi all, I have a program with a QtQuick UI, a backend in C++ including a custom Entity derived from Qt3DCore::QEntity that is display in a Scene3D. The program works with Qt-5.9.3. But with precompiled Qt-5.10.0 (“Using Qt version 5.10.0 in C:/Qt/5.10.0/msvc2017_64/lib”) I get the same

[Interest] Qt3D, custom mesh and materials

Another question for the Qt3D experts: I created a custom mesh by defining the following attributes: position, normal, index, texCoord. If I use a PhongMaterial, the mesh displays nicely: auto material = new Qt3DExtras::QPhongMaterial(); material->setAmbient(QColor(85, 85, 128));
