Description

Graphics-lifecycle sample app extends the rne-triangle sample app to support rt and suspend/resume. The following key features are demonstrated:

How to use wayland and OpenGL ES to render graphics
How to get keyboard/remote input
How to get screen resolution
How to setup and register an object with rt
How to handle suspend/resume

Member Function Documentation

◆ suspend()

rtError GraphicsLifeCycle::suspend ( )

@brief This API is called by the app manager to suspend the currently running application.

Apps when suspended should free all graphics and AV resources. Uses minimal CPU and RAM while running in the background. The app manager invokes suspend call from the app through rt.

@return Returns RT_OK on success, appropriate error code otherwise.

Definition at line 47 of file LifeCycle.cpp.

◆ resume()

rtError GraphicsLifeCycle::resume ( )

This API is used to resume the application suspended by the app manager.

Returns: Returns RT_OK on success, appropriate error code otherwise.

Definition at line 53 of file LifeCycle.cpp.

◆ setRtUtils()

void GraphicsLifeCycle::setRtUtils ( RtUtils * rtUtils )

This initializes the rt object, sets the event listeners and also set the remote ready flag.

Parameters

[in] rtUtils rt object.

Returns: Returns RMF_SUCCESS on success, appropriate error code otherwise.

Definition at line 37 of file LifeCycle.cpp.

◆ setCallbacks()

void GraphicsLifeCycle::setCallbacks ( const Callbacks & cb )

@brief This API sets the callback functions.

Apps should support a suspend and resume option if needed so they can start quickly and stay running in the background.

@param[in] cb   Callback functions to set.

@return Returns RMF_SUCCESS on success, appropiate error code otherwise.
