Detailed Description

interface to the underlying SDL_VideoSurface

Member Enumeration Documentation

enum Wt::SDLDisplay::DefaultSurface

Enumerator:

defaultWidth
defaultHeight
defaultDepth

Constructor & Destructor Documentation

Wt::SDLDisplay::SDLDisplay	(	int	w = defaultWidth,
		int	h = defaultHeight,
		int	depth = defaultDepth,
		int	flags = 0
	)

Initialize the target screen surface.

Wt::SDLDisplay::SDLDisplay

(

SDLSurface &

[protected]

copy constructor takes ownership. It is called from load()

void Wt::SDLDisplay::resize	(	int	w,
		int	h
	)

resize the SDL window

Note:

first we delete our reference to VideoSurface before SDL frees it under our feet SDL proctects us from deleting the Display surface and auto deletes it in case we call SDL_SetVideoMode, However SDL does not protect against deletion of the previous VideoSurface.

Reimplemented from Wt::SDLSurface.

int Wt::SDLDisplay::setGamma	(	float	red,
		float	green,
		float	blue
	)

int Wt::SDLDisplay::setGammaRamp	(	const std::vector< Uint16 > &	red,
		const std::vector< Uint16 > &	green,
		const std::vector< Uint16 > &	blue
	)

???

int Wt::SDLDisplay::toggleFullScreen

Update a region on the surface.

void Wt::SDLDisplay::update

(
