Qt Mobile Development Nokia Devices - Getting started with Nokia Qt SDK (part 3/3)
summary
Demonstrates building a mobile Qt app end-to-end: designs UI in Qt Designer, implements logic with signals and slots (synchronous, order unspecified), compiles for desktop, Qt Simulator and devices, and debugs on-device via TRK. Uses Smart Installer to check for and download missing runtimes (example: Qt 4.6.3 and Qt Mobility 1.0.2); only ~7 devices supported now, ~20 promised by year end. Shows a working BMI app that runs on desktop, simulator and after device configuration, and notes N8 ships with Qt 4.6.4 and OpenVG hardware acceleration.
