Functions

◆ blit()

void PvrEglScreen::blit	(	const QImage &	image,
		const QPoint &	topLeft,
		const QRegion &	region
	)

virtual

Copies the given region in the given image to the point specified by topLeft using device coordinates.

This function is called from the exposeRegion() function; it is not intended to be called explicitly.

Reimplement this function to make use of Adding an Accelerated Graphics Driver to Qt for Embedded Linux{accelerated hardware}. Note that this function must be reimplemented if the framebuffer format is not supported by Qt for Embedded Linux (See the Qt for Embedded Linux Display Management{Display Management} documentation for more details).

See also: exposeRegion(), solidFill(), blank()

Reimplemented from QScreen.

Definition at line 169 of file pvreglscreen.cpp.

 {
     QGLScreen::blit(img, topLeft, region);
     sync();
 }

◆ chooseContext()

bool PvrEglScreen::chooseContext	(	QGLContext *	context,
		const QGLContext *	shareContext
	)

virtual

Initializes the context and sets up the QGLWindowSurface of the QWidget of context based on the parameters of context and based on its own requirements.

Since: 4.3

The format() of context needs to be updated with the actual parameters of the OpenGLES drawable that was set up.

shareContext is used in the same way as for QGLContext. It is the context with which context shares display lists and texture ids etc. The window surface must be set up so that this sharing works.

Returns true in case of success and false if it is not possible to create the necessary OpenGLES drawable/context.

Since 4.4.2, this function will be not be called if options() indicates that a native window or pixmap drawable can be created via the functions in the surfaceFunctions() object.

This function is obsolete in Qt 4.5 and higher. Use surfaceFunctions() instead.

     ::close(ttyfd);
     ttyfd = -1;
 }

◆ connect()

bool PvrEglScreen::connect ( const QString & displaySpec )

virtual

This function is called by every Qt for Embedded Linux application on startup, and must be implemented to map in the framebuffer and the accelerated drivers that the graphics card control registers.

Note that connect must be called before the initDevice() function.

Ensure that true is returned if a connection to the screen device is made. Otherwise, return false. Upon making the connection, the function should read out the parameters of the framebuffer and use them as required to set this class's protected variables.

The displaySpec argument is passed by the QWS_DISPLAY environment variable or the -display command line parameter, and has the following syntax:

[screen driver][:driver specific options][:display number]

For example, to use the mach64 driver on fb1 as display 2:

Mach64:/dev/fb1:2
