Qt for Tizen: 1.0 Alpha 4 Release
- No Virtual Keyboard support. Planned for Alpha 5, it will be either integrated with default Tizen’s keyboard or implemented with Qt.
- No screen orientation changes on emulator. Screen orientation handling is based on orientation sensor – it looks like it returns confusing values on emulator.
- No JIT Qml support on RD-PQ (It is transparent for developers – application starts a little slower). JIT support will be added when 5.2 will be released.
- Emulator – crashes when closing QtQuick appllication. Problem is related to corrupt OpenGL stack on emulator. As QtQuick Scene Graph uses OpenGL it has impact on QtQuick application ran in emulator.
