Use a Timer to react to events in another thread
|
||
|
|
------------------------------------------------
|
||
|
|
|
||
|
|
You should never modify Blender data at arbitrary points in time in separate threads.
|
||
|
|
However you can use a queue to collect all the actions that should be executed when Blender is in the right state again.
|
||
|
|
Pythons `queue.Queue` can be used here, because it implements the required locking semantics.
