void moveToThread( QThread *thread );
|

%Docstring
|
|
Moves the pipe to another ``thread``.
|
|
|
|
This effects all QObject derived interfaces in the pipe, and follows the
|
|
same behavior as QObject.moveToThread. Specifically, it is permitted to
|
|
PUSH the pipe from the current thread to another thread, but NOT to PULL
|
|
a pipe from another thread over to the current thread. Pulling is only
|
|
supported by first pushsing the pipe from its current thread to a
|
|
``None`` thread, and then later pulling to the current thread. See
|
|
QObject documentation for more details.

Inserts a new known interface in default place or replace interface of

the same role if it already exists.

Known interfaces are:

For other interfaces the position of the interface in the pipe must be
|
|
explicitly specified using the :py:func:`~QgsRasterPipe.insert` method.
