		const EGLDisplay &	eglDisplay,
		const EGLConfig &	eglConfig,
		int	bufferCount,
		int	usageFlags
	)

explicit

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.

◆ setPropertyDisplay()

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

inlinenoexcept

Sets the display for this window.

Parameters

qnxDisplay Display to set.

Returns: True on success, false on failure.
