## Member Function Documentation

### QRemoteObjectPendingCall::Error QRemoteObjectPendingCall::error() const

Returns the error, if any, from the remote call.

### 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.
