Detailed Description

Class representing a QNX EGL window.

Constructor & Destructor Documentation

◆ QnxEGLWindow() [1/2]

kanzi::qnx::QnxEGLWindow::QnxEGLWindow	(	const QnxContext &	qnxContext,
		optional< windowing::Size >	windowSize,
		int	bufferCount,
		int	usageFlags,
		optional< int >	pipelineID,
		optional< int >	selfLayout )

explicit

Constructor.

Parameters

qnxContext	QNX context.
windowSize	Window size.
bufferCount	Amount of buffers to create for a window.
usageFlags	Usage flag bit mask to use for a window.
pipelineID	QNX Screen pipeline ID.
selfLayout	QNX window self layout option.

Since: Kanzi 3.9.11 Added windowSize and pipelineID parameters.; Kanzi 3.9.14 Added selfLayout property for the window.

◆ QnxEGLWindow() [2/2]

kanzi::qnx::QnxEGLWindow::QnxEGLWindow	(	const QnxContext &	qnxContext,
		const EGLDisplay &	eglDisplay,
		const EGLConfig &	eglConfig,
		optional< windowing::Size >	windowSize,
		int	bufferCount,
		int	usageFlags,
		optional< int >	pipelineID,
		optional< int >	selfLayout )

explicit

Constructor.

Parameters

qnxContext	QNX context.
eglDisplay	EGL display.
eglConfig	EGL config.
windowSize	Window size.
bufferCount	Amount of buffers to create for a window.
usageFlags	Usage flag bit mask to use for a window.
pipelineID	QNX Screen pipeline ID.
selfLayout	QNX window self layout option.

Since: Kanzi 3.9.11 Added windowSize parameter.; Kanzi 3.9.14 Added selfLayout property for the window.

Member Function Documentation

◆ makeCurrent()

bool kanzi::qnx::QnxEGLWindow::makeCurrent	(	const EGLDisplay &	eglDisplay,
		const EGLContext &	eglContext )

inlinenoexcept

Binds a window surface to a context and the current thread.

Parameters

eglDisplay	EGL display connection of the EGL context.
eglContext	EGL context to bind to.

Returns: True on success, false on failure.

◆ swapBuffers()

bool kanzi::qnx::QnxEGLWindow::swapBuffers ( const EGLDisplay & eglDisplay ) const

inline

Posts rendering results.

Implicitly flushes the rendering pipeline and executes all received rendering commands before posting.

Parameters

eglDisplay EGL display connection.

See also: swapInterval().

Returns: True on success, false on failure.

Postcondition: egl::getError() returns EGL_SUCCESS.

◆ show()

bool kanzi::qnx::QnxEGLWindow::show ( )

inlinenoexcept

Shows this window.

Returns: True on success, false on failure.

◆ tryGetSize()

KZ_NO_DISCARD optional< windowing::Size > kanzi::qnx::QnxEGLWindow::tryGetSize ( ) const

inlinenoexcept

Tries to get the size for this window.

Return values

nullopt Getting the size failed.

Returns: Window size in pixels.

◆ setSize()

bool kanzi::qnx::QnxEGLWindow::setSize ( windowing::Size windowSize )

inlinenoexcept

Sets size for this window.

Parameters

windowSize Window size to set in pixels.

Returns: True on success, false on failure.

◆ setPosition()

bool kanzi::qnx::QnxEGLWindow::setPosition ( windowing::Position windowPosition )

inlinenoexcept

Sets position for this window.

Child window and embedded window positions are relative to their parent window positions.

Parameters

windowPosition Window position to set in pixels.

Returns: True on success, false on failure.

◆ setUsageFlags()

bool kanzi::qnx::QnxEGLWindow::setUsageFlags ( int usageFlags )

inlinenoexcept

Sets usage flags for this window.

Parameters

usageFlags Usage flag bit mask to use.

Returns: True on success, false on failure.

◆ setZOrder()

bool kanzi::qnx::QnxEGLWindow::setZOrder ( int zorder )

inlinenoexcept

Sets z-order for this window.

Parameters

zorder Z order to set.

Returns: True on success, false on failure.

◆ setTitle()

bool kanzi::qnx::QnxEGLWindow::setTitle ( string_view windowTitle )

inlinenoexcept

Sets a window title.

Parameters

windowTitle Window title to set.

Returns: True on success, false on failure.

◆ createBuffers()

bool kanzi::qnx::QnxEGLWindow::createBuffers ( int bufferCount )

inlinenoexcept

Creates buffers for this window.

Parameters

bufferCount Amount of buffers to create.

Returns: True on success, false on failure.

◆ trySetPropertyDisplay()

bool kanzi::qnx::QnxEGLWindow::trySetPropertyDisplay ( const QnxDisplay & qnxDisplay )

inlinenoexcept

Sets the display for this window.

Parameters

qnxDisplay Display to set.

Returns: True on success, false on failure.

◆ getNativeWindowHandle()

KZ_NO_DISCARD optional< QnxWindow::NativeHandleType > kanzi::qnx::QnxEGLWindow::getNativeWindowHandle ( ) const

noexcept

Gets the associated window handle.

Return values

nullopt Error has occured.

Returns: Native window handle.

◆ getNativeSurfaceHandle()

KZ_NO_DISCARD optional< void * > kanzi::qnx::QnxEGLWindow::getNativeSurfaceHandle ( ) const

noexcept

Gets associated native EGL surface handle.

Return values

nullopt Error has occured.

Returns: The handle of associated surface object.
