Member Function Documentation

◆ loadVideoMode()

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

inlineoverridevirtual

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 LibretroOpenGLGraphics::refreshScreen ( )

overridevirtual

Refresh the screen contents.

Implements OpenGL::OpenGLGraphicsManager.

◆ setSystemMousePosition()

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

inlineoverridevirtual

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.

◆ gameNeedsAspectRatioCorrection()

bool LibretroOpenGLGraphics::gameNeedsAspectRatioCorrection ( ) const

inlineoverrideprotectedvirtual

Returns: whether or not the game screen must have aspect ratio correction applied for correct rendering.

Reimplemented from OpenGL::OpenGLGraphicsManager.

◆ handleResizeImpl()

void LibretroOpenGLGraphics::handleResizeImpl	(	const int	width,
		const int	height
	)

overrideprotectedvirtual

Backend-specific implementation for updating internal surfaces that need to reflect the new window size.

Reimplemented from OpenGL::OpenGLGraphicsManager.

The documentation for this class was generated from the following file:
