Member Function Documentation

◆ notifyEvent()

bool OpenGLSdlGraphicsManager::notifyEvent ( const Common::Event & event )

overridevirtual

Notify the observer of an incoming event.

An observer is supposed to 'eat' the event, with returning true, when it wants to prevent other observers from receiving the event. A usage example here is the keymapper: If it processes an Event, it should 'eat' it and create a new event, which the EventDispatcher will then catch.

Parameters

event The event that is incoming.

Return values

true	If the event should not be passed to other observers, false otherwise.

Implements Common::EventObserver.

◆ notifyVideoExpose()

void OpenGLSdlGraphicsManager::notifyVideoExpose ( )

overridevirtual

Notify the graphics manager that the graphics needs to be redrawn, since the application window was modified.

This is basically called when SDL_VIDEOEXPOSE was received.

Implements SdlGraphicsManager.

◆ notifyResize()

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

overridevirtual

Notify the graphics manager about a resize event.

It is noteworthy that the requested width/height should actually be set up as is and not changed by the graphics manager, since otherwise it may lead to odd behavior for certain window managers.

It is only required to overwrite this method in case you want a resizable window. The default implementation just does nothing.

Parameters

width	Requested window width.
height	Requested window height.

Reimplemented from SdlGraphicsManager.

◆ loadVideoMode()

bool OpenGLSdlGraphicsManager::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 OpenGLSdlGraphicsManager::refreshScreen ( )

overrideprotectedvirtual

Refresh the screen contents.

Implements OpenGL::OpenGLGraphicsManager.

◆ handleResizeImpl()

void OpenGLSdlGraphicsManager::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:

backends/graphics/openglsdl/openglsdl-graphics.h
