The reference image includes a second HMI, also written with Qt, that demonstrates how to run a single,
monolithic HMI without packaging apps into Blackberry ARchive (BAR) files.
The Full Screen HMI has a simple user
interface and doesn't use the
Application and Window Management components, such as the
Authorization Manager (
authman) or
Application Launcher
(
launcher). To display the simple HMI instead of the Home screen, change the
following line in the
/var/etc/services-enabled file using
elvis or
vi:
QTHOMESCREEN:true
to
QTHOMESCREEN:false
Then, save the
services-enabled file and
restart your board. After the board restarts, the simple HMI showing the QNX logo and the target's IP
address appears:
Note: It's expected that developers write their own Full Screen HMI, as the sample provided is intended just to
demonstrate how to start Qt runtime and its dependencies (e.g., graphics/Screen,
multimedia/mm-renderer).
