Sleeping	The application is sleeping. The OpenGL graphics context is destroyed.
Quitting	The application is in the process of quitting without errors.
Error	The application has encountered an error and exits immediately.

Constructor & Destructor Documentation

kanzi::Application::Application ( )

explicit

Constructs the application object.

virtual kanzi::Application::~Application ( )

virtual

Destructs the application object.

Member Function Documentation

void kanzi::Application::initialize ( const SystemProperties & systemProperties )

Initializes the application to a consistent state.

This is the first function called by the application framework after constructing the application. This function tries to read the file application.cfg and shouldn't be called before the file system of the operating system has been initialized.

The default behavior can be changed by overriding initializeOverride().

Parameters

systemProperties Command line parameters of the program.

void kanzi::Application::uninitialize ( )

Uninitializes the application.

This is the last function called by the application framework before destruction.

The default behavior can be changed by overriding uninitializeOverride().

void kanzi::Application::initializeGL ( )

Initializes the graphics language subsystem.

This function is called by the application framework before entering the program main loop, but after a GL context has been activated. It initializes OpenGL-related subsystems.

The default behavior can be changed by overriding initializeGLOverride().

void kanzi::Application::uninitializeGL ( )

Uninitializes the graphics language subsystem.

This function is called by the application framework after exiting the program main loop, but before a GL context has been deactivated. It undeploys all GPU resources.

The default behavior can be changed by overriding uninitializeGLOverride().

void kanzi::Application::suspendGL ( )

Suspends the graphics language subsystem.

This function is called by the application framework during application suspension, on systems where the graphics language resources are not guaranteed to be retained until the application resumes. It undeploys all GPU resources and reschedules them for redeployment.

When your applications suspends, the GPU resources not stored in a .kzb file become invalid. Destroy these resources and recreate them on resume. Make sure that after recreating a resource the pointers are correct. Kanzi automatically restores all other resources.

The default behavior can be changed by overriding suspendGLOverride().

void kanzi::Application::resumeGL ( )

Resumes the graphics language subsystem.

This function is called by the application framework during application resume, if suspendGL() was called during suspension. It deploys GPU resources that were undeployed during suspendGL().

The default behavior can be changed by overriding resumeGLOverride().
