Member Function Documentation

◆ notifyResize()

void iOSGraphicsManager::notifyResize	(	const int	width,
		const int	height
	)

overridevirtual

Notify the graphics manager about a resize event. This happens on iDevices when switching to portrait mode or landscape mode.

Implements iOSCommonGraphics.

◆ getState()

virtual iOSCommonGraphics::State iOSGraphicsManager::getState ( ) const

overridevirtual

Gets the current state of the graphics manager.

Implements iOSCommonGraphics.

◆ setState()

virtual bool iOSGraphicsManager::setState ( const iOSCommonGraphics::State & state )

overridevirtual

Sets up a basic state of the graphics manager.

Implements iOSCommonGraphics.

◆ setSystemMousePosition()

void iOSGraphicsManager::setSystemMousePosition	(	const int	x,
		const int	y
	)

inlineoverrideprotectedvirtual

Sets the position of the hardware mouse cursor in the host system, relative to the window.

Parameters

x	X coordinate in window coordinates.
y	Y coordinate in window coordinates.

Implements WindowedGraphicsManager.

◆ loadVideoMode()

bool iOSGraphicsManager::loadVideoMode	(	uint	requestedWidth,
		uint	requestedHeight,
		const Graphics::PixelFormat &	format
	)

overrideprotectedvirtual

Set up the requested video mode. This takes parameters which describe what resolution the game screen requests (this is possibly aspect ratio corrected!).

A sub-class should take these parameters as hints. It might very well set up a mode which it thinks suites the situation best.

requestedWidth This is the requested actual game screen width.

Parameters

requestedHeight	This is the requested actual game screen height.
format	This is the requested pixel format of the virtual game screen.

Returns: true on success, false otherwise

Implements OpenGL::OpenGLGraphicsManager.

◆ refreshScreen()

void iOSGraphicsManager::refreshScreen ( )

overrideprotectedvirtual

Refresh the screen contents.

Implements OpenGL::OpenGLGraphicsManager.
