Constructor & Destructor Documentation

EQ_API eq::qt::Window::Window	(	NotifierInterface &	parent,
		const WindowSettings &	settings,
		QScreen *	screen,
		QThread *	thread
	)

Create a new window using Qt.

The actual window will be a QWindow or a QOffscreenSurface depending on the window settings. The window won't be realized until configInit is called.

Parameters

parent	The eq::Window parent window interface that uses this system window.
settings	The window settings. The GL context format will be derived from these.
screen	the Qt screen to create the window on.
thread	the Qt thread running the window.

Version: 1.9

EQ_API eq::qt::Window::~Window ( )

final

Destruct this Qt window.

Version: 1.7.3

Member Function Documentation

EQ_API void eq::qt::Window::configExit ( )

overridevirtual

Version: 1.7.3

Implements eq::SystemWindow.

EQ_API bool eq::qt::Window::configInit ( )

overridevirtual

Initialize this window for the Qt window system.

The window will be only usable by the thread that invokes this functions. Otherwise Qt thread affinity constraints will be violated.

Returns: true if the initialization was successful, false otherwise.

Version: 1.7.3

Implements eq::SystemWindow.

EQ_API void eq::qt::Window::doneCurrent ( ) const

overridevirtual

Version: 1.10

Reimplemented from eq::GLWindow.

EQ_API QOpenGLContext* eq::qt::Window::getContext ( ) const

The context won't be ready to be used until configInit is called.

Returns: the Open GL context used by this window.

Version: 1.9

EQ_API QObject* eq::qt::Window::getEventProcessor ( )

Use this object to make Qt events reach eq::Config when using this window for offscreen rendering with shared context mode (e.g.

to embed Equalizer output into a Qt GUI).

Don't send events directly to the object unless you know what you're doing, use QApplication::postEvent instead.

Returns: the object to which forward Qt events.

Version: 1.9

EQ_API void eq::qt::Window::joinNVSwapBarrier	(	const uint32_t	group,
		const uint32_t	barrier
	)

overridevirtual

Version: 1.7.3

Reimplemented from eq::GLWindow.

void eq::qt::Window::moveContextToThread ( QThread * thread )

Move OpenGLContext object to given thread.

Version: 1.10

EQ_API bool eq::qt::Window::processEvent	(	EventType	type,
		QEvent *	qEvent,
		SizeEvent &	event
	)
