Struct qt_gui::QSurface

#[repr(C)]pub struct QSurface { /* fields omitted */ }

The QSurface class is an abstraction of renderable surfaces in Qt.

C++ class: QSurface.

C++ documentation:

The QSurface class is an abstraction of renderable surfaces in Qt.

The size of the surface is accessible with the size() function. The rendering specific attributes of the surface are accessible through the format() function.

Methods

impl QSurface

pub unsafe fn copy_from(
    &self,
    other: impl CastInto<Ref<QSurface>>
) -> Ref<QSurface>

The QSurface class is an abstraction of renderable surfaces in Qt.

Calls C++ function: QSurface& QSurface::operator=(const QSurface& other).

C++ documentation:

The QSurface class is an abstraction of renderable surfaces in Qt.

The size of the surface is accessible with the size() function. The rendering specific attributes of the surface are accessible through the format() function.

pub unsafe fn format(&self) -> CppBox<QSurfaceFormat>

Returns the format of the surface.

Calls C++ function: pure virtual QSurfaceFormat QSurface::format() const.

C++ documentation:

Returns the format of the surface.

pub unsafe fn size(&self) -> CppBox<QSize>

Returns the size of the surface in pixels.

Calls C++ function: pure virtual QSize QSurface::size() const.

C++ documentation:

Returns the size of the surface in pixels.

pub unsafe fn static_meta_object() -> Ref<QMetaObject>

This is supported on cpp_lib_version="5.12.2" or cpp_lib_version="5.13.0" or cpp_lib_version="5.14.0" only.

Returns a reference to the staticMetaObject field.

pub unsafe fn supports_opengl(&self) -> bool

Returns true if the surface is OpenGL compatible and can be used in conjunction with QOpenGLContext; otherwise returns false.

Calls C++ function: bool QSurface::supportsOpenGL() const.

C++ documentation:
