Member Function Documentation

◆ handle()

virtual PlatformHandleType STK::OpenGLContext::handle ( ) const
pure virtual

Get unique handle based on the underlying GL Context object, for example EGLContext.

Implemented in StkQt::OpenGLContext, STK::EglOpenGLContext, and STK::TestOpenGLContext.

◆ initialize()

bool STK::OpenGLContext::initialize ( )
virtual

Returns false if GL function setup or platform-specific initialization fails.

Reimplemented in STK::EglOpenGLContext.
