You can replace the QNX full screen HMI with one you have developed using the QNX Qt Development Framework.
SLM launches the full screen HMI via a script, qthmi-start.sh. This action is configured in $QNX_DEPLOYMENT_WORKSPACE/target/product/AnM/etc/slm-config-all.xml:
<SLM:component name="hmi"> <SLM:command>/base/scripts/qthmi-start.sh</SLM:command> <SLM:stop stop="signal">SIGTERM</SLM:stop> <SLM:envvar>APP_MEDIA_KB_PATH=/base/usr/anm/bin/keyboard</SLM:envvar> <SLM:envvar>APP_MEDIA_ASSET_PATH=/base/usr/anm/share/appmedia11</SLM:envvar> <SLM:envvar>QQNX_PHYSICAL_SCREEN_SIZE=150,90</SLM:envvar> <SLM:depend>symlink_hmi</SLM:depend> <SLM:depend>symlink_base</SLM:depend> <SLM:depend>iopkt</SLM:depend> <SLM:depend>pps</SLM:depend> <SLM:depend>calib-done</SLM:depend> <SLM:depend>keyboard</SLM:depend> <SLM:depend>screen-ready</SLM:depend> </SLM:component>
The qthmi-start.sh script is located in $QNX_DEPLOYMENT_WORKSPACE/target/product/AnM/scripts/. It invokes the executable called QtSimpleHMI, which is located in the base_dir/target/qnx6/architecture/usr/anm/bin directory.
The QtSimpleHMI is included in the basefs.anm.qt.xml fileset in the $QNX_DEPLOYMENT_WORKSPACE/infra/product/AnM/filesets/ directory.
