Member Function Documentation
[protected] QRemoteObjectPendingCall::QRemoteObjectPendingCall(QRemoteObjectPendingCallData *dd)
Default constructs an instance of QRemoteObjectPendingCall.
QRemoteObjectPendingCall::QRemoteObjectPendingCall(const QRemoteObjectPendingCall &other)
Default constructs an instance of QRemoteObjectPendingCall.
QRemoteObjectPendingCall::QRemoteObjectPendingCall()
Default constructs an instance of QRemoteObjectPendingCall.
QRemoteObjectPendingCall &QRemoteObjectPendingCall::operator=(const QRemoteObjectPendingCall &other)
Copy-assignment operator.
QRemoteObjectPendingCall::~QRemoteObjectPendingCall()
Destroys the instance of QRemoteObjectPendingCall.
QRemoteObjectPendingCall::Error QRemoteObjectPendingCall::error() const
Returns the error, if any, from the remote call.
[static] QRemoteObjectPendingCall QRemoteObjectPendingCall::fromCompletedCall(const QVariant &returnValue)
bool QRemoteObjectPendingCall::isFinished() const
Returns true if the remote call has finished, false otherwise.
A finished call will include a returnValue or error.
QVariant QRemoteObjectPendingCall::returnValue() const
Returns the return value of the remote call.
returnValue will only be valid when the remote call has finished and there are no errors.
bool QRemoteObjectPendingCall::waitForFinished(int timeout = 30000)
Blocks for up to timeout milliseconds, until the remote call has finished.
Returns true on success, false otherwise.
