Detailed Description

Each display must have a renderer, even if it is the NoRenderer, the NoRenderer is for situations where the control is performed exclusively by a remote device.

Constructor & Destructor Documentation

~MenuRenderer()

virtual MenuRenderer::~MenuRenderer ( )

inlinevirtual

virtual destructor is required by the language

Member Function Documentation

initialise()

virtual void MenuRenderer::initialise ( )

pure virtual

This is called when the menu manager is created, to let the display perform one off tasks to prepare the display for use

Implemented in tcgfx::BaseGraphicalRenderer, BaseMenuRenderer, and NoRenderer.

tryTakeSelectIfNeeded()

virtual bool MenuRenderer::tryTakeSelectIfNeeded ( int  currentReading, RenderPressMode  press  )

pure virtual

Allows the select key to be overriden for situations such as dialogs and other special cases.

Parameters

held	true when the select was held down.

Returns

true to indicate we consumed the event, otherwise false.

Implemented in NoRenderer, and BaseMenuRenderer.

getDialog()

virtual BaseDialog* MenuRenderer::getDialog ( )

pure virtual

Gets the dialog instance that is associated with this renderer or NULL if this renderer cannot display dialogs (only NoRenderer case).

Implemented in tcgfx::BaseGraphicalRenderer, and NoRenderer.

getBuffer()

char* MenuRenderer::getBuffer ( )

inline

Gets the buffer that is used internally for render buffering.

getBufferSize()

uint8_t MenuRenderer::getBufferSize ( )

inline

Gets the buffer size of the buffer

getRendererType()

RendererType MenuRenderer::getRendererType ( )

inline

Returns if this is a no display type renderer or a base renderer type.
