SafeRenderer::QSafeEventOutputVerificationStatusReply	Send as reply to the EventOutputVerificationStatusRequest request
SafeRenderer::QSafeEventOutputVerificationStatusRequest	Used to request the output verification results
SafeRenderer::QSafeEventOutputVerificationVerifyItem	Used to update the output CRC value of the single safe item
SafeRenderer::QSafeEventSender	Abstract communication interface to the safe renderer processes
SafeRenderer::QSafeEventSetText	Changes the text in layout
SafeRenderer::QSafeEventSystem	Sends the system event state change

SafeRenderer::QSafeFontCache	Caches a font
SafeRenderer::QSafeFontLoader	Loads a specified font
SafeRenderer::QSafeLayout	Abstract class for accessing the Qt Safe Renderer layout data
SafeRenderer::QSafeLayoutFileReader	Reads the layout data from a file
SafeRenderer::QSafeLayoutResourceReader	Reads the layout data from the Qt's resource structure
SafeRenderer::QSafePoint	Holds the x-coordinate and y-coordinate
SafeRenderer::QSafeRect	Defines a rectangle in the plane
SafeRenderer::QSafeRenderer	Renders the safe layout
SafeRenderer::QSafeSize	Holds the height and width variables
SafeRenderer::QSafeStateFileReader	Loads the state definition from the file
SafeRenderer::QSafeStateLoader	Loads the state definition file
SafeRenderer::QSafeStateResourceReader	Loads the state definition from the resource data
SafeRenderer::QSafeString	Contains functions for the string manipulation
SafeRenderer::QSafeTextLayout	Contains functions for the text layout manipulation
SafeRenderer::QSafeTouch	Contains parameters that describe a touch event
SafeRenderer::QStringSplitter	Splits the string
SafeRenderer::SafeWindow	Implements the AbstractWindow interface
SafeRenderer::SafeWindowException	Abstract exception class for SafeWindow
SafeRenderer::StateManager	Maintains the state of the indicators
SafeRenderer::TestVerifier	The output verifier implementation for the Qt GUI adaptation
SafeRenderer::VerifyRegion	API to monitor graphics output

Note: The implementation of the safety requirements concerns only content inside the SafeRenderer namespace.

Deprecated Qt Safe Renderer classes

The following Qt Safe Renderer C++ classes are now obsolete. Obsolete classes are no longer maintained. They are provided to keep old source code working, but they can be removed in a future release. We strongly advise against using these classes in new code.

Note: You can use QML states for changing the color and event positions. For more information, see Changing States and Important Concepts in Qt Quick - States, Transitions and Animations.
