container removeInstance goal of the option postpone_emit

[Cuq 172]

Hello,

 

I don't quite understand the effect of the postpone_emit option on the removeInstance function in Cura's management for the ContainerStack ? If someone could enlighten me on this point it would be nice. @nallath ?

If you remove an instance of a setting from a container, a signal is emitted to update the container, which causes other signals to emit, and a whole set of effects start to happen. If you want to remove multiple instances, then it would cause a lot of unnecessary signals being emitted inbetween. The postpone_emit option basically tells Cura to perform the change to the container, but wait before telling the rest of Cura until you are done with the last manipulation of the container.
