Player and expansion communication......

[Lindon]

@David-Healey said in Player and expansion communication......:

@Lindon If you set the current expansion to "" that will trigger the unload action, so you can respond to that. I'm not sure if that reruns the player's on init but you could test.

I think a timer and polling on the message thread is the way to go, the timer won't run when the interface is minimised anyway.

Yeah its the expansion that will be setting the current expansion to "" - so I'm not sure how the player responds to that....I cant see a expansion changed callback or listener...

ExpansionHandler.setExpansionCallback() Not sure if it works in this scenario the way you need but give it a try.

Long time that I worked on this, but setting an empty expansion in a full player plugin should get you back to the shell - it's onInit callback should be compiled too again.

Im not sure I understand what you mean, no actually I clearly dont understand what you mean....

I load the player - its init executes,
I load an Full instrument expansion from the player - its init executes
I unload the instrument, from within the instrument, the player reloads.... does its init execute? Or does it some how magically retain its own state ?

does its init execute?

We think yes but try it and see

[Lindon]

@David-Healey Ok will do but assuming YES...

Problem #2:

Just before I unload I save a file....so this:

myFile.saveObject(myJSON);
myExpansionHandler.getCurrentExpansion("");

What happens?
Is the file save async? or better still blocking?
is it running in a differnt thread?
will it even happen?
Will it get aborted?
How will I know when its finished?

[Lindon]

@Lindon or do I have to do this....

myFile.saveObject(myJSON);
runSomeShittyTimerToDoTheUnload();

As you may surmise - I dont find it "elegant"

[David Healey]

@Lindon Pretty sure it's synchronous because it's calling JUCE's replaceWithText function and returning a bool.

So you could probably do something like

if (f.writeObject(myJson))
    unloadTheExpansion

@David-Healey yup sync

@David-Healey yup sync

Good news then.. thanks.
@David-Healey and thanks to you too.
