System.ObjectMethodSystem.VoidSet this ModuleCallback as a temporary handler. will be called on the same thread as the gnome-vfs operation that invokes it. The temporary handler is set per-thread. removes the most recently set temporary handler. The temporary handlers are treated as a first-in first-out stack.Use this function to set a temporary callback handler for a single call or a few calls. You can use to set a callback function that will establish a permanent global setting for all threads instead.MethodSystem.VoidRemove the temporary handler set with . If another temporary handler was previously set on the same thread, it becomes the current handler. Otherwise, the default handler, if any, becomes current.The temporary handlers are treated as a first-in first-out stack.MethodSystem.VoidSet this as the default handler. will be called on the same thread as the gnome-vfs operation that invokes it. The default value is shared for all threads, but setting it is thread-safe.Use this function if you want to set a handler to be used by your whole application. You can use to set a callback function that will temporarily override the default on the current thread instead. Or you can also use to set an async callback function.MethodSystem.VoidSet as a temprary async handler. will be called from a callback on the main thread. It will be passed a response function which should be called to signal completion of the callback. The callback function itself may return in the meantime.The temporary async handler is set per-thread. removes the most recently set temporary temporary handler.

These properties are only valid during the callback activation.
