“Qtopia is Trolltech’s development framework, graphics
framework, and application stack for Linux-based mobile devices of
all kinds. Initially popularized on Sharp’s Zaurus PDA, Qtopia

system — important considerations for resource-constrained
battery-powered mobile devices. thousands of commercial and open
source Qtopia applications have appeared through the years.”
