Detailed description

!=

Signature: [const] bool != (const QElapsedTimer other)

Description: Method bool QElapsedTimer::operator!=(const QElapsedTimer &other)

==

Signature: [const] bool == (const QElapsedTimer other)

Description: Method bool QElapsedTimer::operator==(const QElapsedTimer &other)

MachAbsoluteTime

Signature: [static,const] QElapsedTimer_ClockType MachAbsoluteTime

Description: Enum constant QElapsedTimer::MachAbsoluteTime

Python specific notes:
The object exposes a readable attribute 'MachAbsoluteTime'. This is the getter.

MonotonicClock

Signature: [static,const] QElapsedTimer_ClockType MonotonicClock

Description: Enum constant QElapsedTimer::MonotonicClock

Python specific notes:
The object exposes a readable attribute 'MonotonicClock'. This is the getter.

PerformanceCounter

Signature: [static,const] QElapsedTimer_ClockType PerformanceCounter

Description: Enum constant QElapsedTimer::PerformanceCounter

Python specific notes:
The object exposes a readable attribute 'PerformanceCounter'. This is the getter.

SystemTime

Signature: [static,const] QElapsedTimer_ClockType SystemTime

Description: Enum constant QElapsedTimer::SystemTime

Python specific notes:
The object exposes a readable attribute 'SystemTime'. This is the getter.

TickCounter

Signature: [static,const] QElapsedTimer_ClockType TickCounter

Description: Enum constant QElapsedTimer::TickCounter

Python specific notes:
The object exposes a readable attribute 'TickCounter'. This is the getter.

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

assign

Signature: void assign (const QElapsedTimer other)

Description: Assigns another object to self

clockType

Signature: [static] QElapsedTimer_ClockType clockType

Description: Static method QElapsedTimer::ClockType QElapsedTimer::clockType()

This method is static and can be called without an instance.

create

Signature: void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

destroy

Signature: void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

destroyed?

Signature: [const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

Use of this method is deprecated. Use _destroyed? instead

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

dup

Signature: [const] new QElapsedTimer ptr dup

Description: Creates a copy of self

Python specific notes:
This method also implements '__copy__' and '__deepcopy__'.

elapsed

Signature: [const] long long elapsed

Description: Method qint64 QElapsedTimer::elapsed()

hasExpired

Signature: [const] bool hasExpired (long long timeout)

Description: Method bool QElapsedTimer::hasExpired(qint64 timeout)

invalidate

Signature: void invalidate

Description: Method void QElapsedTimer::invalidate()

isMonotonic?

Signature: [static] bool isMonotonic?

Description: Static method bool QElapsedTimer::isMonotonic()

This method is static and can be called without an instance.

isValid?

Signature: [const] bool isValid?

Description: Method bool QElapsedTimer::isValid()

is_const_object?

Signature: [const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

Use of this method is deprecated. Use _is_const_object? instead

This method returns true, if self is a const reference. In that case, only const methods may be called on self.
