Qt Safe Renderer Indicators: Creating Safety-Critical UI

C

Qt Safe Renderer Examples

After you have installed Qt Safe Renderer, you find the Qt Safe Renderer examples under <Qt installation directory>/Examples. You can build the examples with CMake or qmake (legacy feature).

Qt Safe Renderer provides the following examples:

Example	Target platform(s)	Example path	Description	How to use	MIRSA Compliance
Indicators	A host platform, QNX, INTEGRITY, Embedded Linux	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/indicators	Indicators demonstrates how you can create a safety-critical UI and how you can test it on your target platform.	A standalone example. You can use Indicators together with the Monitor example. On the target device, you also need the Message Proxy example.	The Monitor library is MISRA compliant.
Monitor	A host platform , QNX, INTEGRITY, Embedded Linux	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/monitor	Monitor demonstrates how you can verify the rendering output of the Indicators example.	Use always together with the Indicators example. On the target device, you also need the Message Proxy example. Does not work as a standalone example	No.
Localization	A host platform, QNX, INTEGRITY, Embedded Linux	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/localization	Localization demonstrates how you can localize content in safety-critical QML elements.	A standalone example	No
Event Sender	A host platform, QNX, INTEGRITY, Embedded Linux	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/eventsender	Event Sender demonstrates a real life use case by sending messages about status changes and events into two different application.	Use always together with the Qt Cluster and Telltales examples. On the target device, you also need the Message Proxy example. Does not work as a standalone example. See Testing Safety-Critical Rendering and Events.	No
Telltales	A host platform, QNX, INTEGRITY, Embedded Linux	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/telltales	Telltales demonstrates how you can include Qt Safe Renderer into an application that contains both safety-critical UI elements and non-safety UI elements. Telltales also demonstrates how the safety-critical rendering is done on a separate process. The example uses Qt Cluster's layout files.	Use together with the Qt Cluster and Event Sender examples. On the target device, you also need the Message Proxy example. Does not work as a standalone example. See Testing Safety-Critical Rendering and Events.	No
Qt Cluster	A host platform, QNX, INTEGRITY, Embedded Linux	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/qtcluster	Qt Cluster demonstrates rendering on QNX and INTEGRITY and recovery from the main UI failure.	Use always together with the Telltales and Event Sender examples. On the target device, you also need the Message Proxy example. Does not work as a standalone example. See Testing Safety-Critical Rendering and Events.	No
Message Proxy	The python script runs on a host platform, the message proxy is installed on the target device (QNX, INTEGRITY, Embedded Linux).	<Qt installation directory>/Examples/QtSafeRenderer-<version>/saferenderer/messageproxy	With Message Proxy, you can test the Qt Safe Renderer messaging interface by sending messages to your device via a python script.	Use together with the Telltales and Qt Cluster examples. Use together with the Monitor and Indicators examples. Does not work as a standalone example.	No

In order to build and run the examples, you must have Qt 6.5.x and Qt Creator 10.0.x or later installed on the host platform.
