[−][src]Struct qt_gui::QOpenGLContextGroup

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

The QOpenGLContextGroup class represents a group of contexts sharing OpenGL resources.

C++ class: QOpenGLContextGroup.

C++ documentation:

The QOpenGLContextGroup class represents a group of contexts sharing OpenGL resources.

QOpenGLContextGroup is automatically created and managed by QOpenGLContext instances. Its purpose is to identify all the contexts that are sharing resources.

Methods

impl QOpenGLContextGroup[src]

pub unsafe fn current_context_group() -> QPtr<QOpenGLContextGroup>[src]

Returns the QOpenGLContextGroup corresponding to the current context.

Calls C++ function: static QOpenGLContextGroup* QOpenGLContextGroup::currentContextGroup().

C++ documentation:

Returns the QOpenGLContextGroup corresponding to the current context.

See also QOpenGLContext::currentContext().

pub unsafe fn meta_object(&self) -> Ptr<QMetaObject>[src]

Calls C++ function: virtual const QMetaObject* QOpenGLContextGroup::metaObject() const.

pub unsafe fn qt_metacall(
    &self,
    arg1: Call,
    arg2: c_int,
    arg3: *mut *mut c_void
) -> c_int[src]

Calls C++ function: virtual int QOpenGLContextGroup::qt_metacall(QMetaObject::Call arg1, int arg2, void** arg3).

pub unsafe fn qt_metacast(&self, arg1: *const c_char) -> *mut c_void[src]

Calls C++ function: virtual void* QOpenGLContextGroup::qt_metacast(const char* arg1).

pub unsafe fn shares(&self) -> CppBox<QListOfQOpenglContext>[src]

Returns all the QOpenGLContext objects in this share group.

Calls C++ function: QList<QOpenGLContext*> QOpenGLContextGroup::shares() const.

C++ documentation:

Returns all the QOpenGLContext objects in this share group.

pub unsafe fn static_meta_object() -> Ref<QMetaObject>[src]

Returns a reference to the staticMetaObject field.

pub unsafe fn tr(
    s: *const c_char,
    c: *const c_char,
    n: c_int
) -> CppBox<QString>[src]

Calls C++ function: static QString QOpenGLContextGroup::tr(const char* s, const char* c, int n).

pub unsafe fn tr_utf8(
    s: *const c_char,
    c: *const c_char,
    n: c_int
) -> CppBox<QString>[src]

Calls C++ function: static QString QOpenGLContextGroup::trUtf8(const char* s, const char* c, int n).
