QDBusPendingCall露

PyQt5.QtDBus.QDBusPendingCall: Inherited by QDBusPendingCallWatcher, QDBusPendingReply.

Description露

The QDBusPendingCall class refers to one pending asynchronous call.

A QDBusPendingCall object is a reference to a method call that was sent over D-Bus without waiting for a reply. QDBusPendingCall is an opaque type, meant to be used as a handle for a pending reply.

In most programs, the QDBusPendingCall class will not be used directly. It can be safely replaced with the template-based QDBusPendingReply, in order to access the contents of the reply or wait for it to be complete.

The QDBusPendingCallWatcher class allows one to connect to a signal that will indicate when the reply has arrived or if the call has timed out. It also provides the waitForFinished() method which will suspend the execution of the program until the reply has arrived.

Note: If you create a copy of a QDBusPendingCall object, all information will be shared among the many copies. Therefore, QDBusPendingCall is an explicitly-shared object and does not provide a method of detaching the copies (since they refer to the same pending call)

Methods露

__init__(QDBusPendingCall): Creates a copy of the other pending asynchronous call. Note that both objects will refer to the same pending call.

@staticmethod fromCompletedCall(QDBusMessage) → QDBusPendingCall

Creates a QDBusPendingCall object based on the message msg. The message must be of type ErrorMessage or ReplyMessage (that is, a message that is typical of a completed call).

This function is useful for code that requires simulating a pending call, but that has already finished.
