Post init callback

[Oli Ullmann]

@Lindon
You could load a default preset when you load the plug-in. Create a Preset hander and set the post load callback:

UserPresetHandler.setPostCallback(var presetPostCallback)

Maybe this works?

All the best

@Oli-Ullmann well even if it does it will p**s off the user base - every time they start the plugin - like in loading an already saved project in their DAW - we get the wrong preset loaded..or at least teh risk of that.

No what we need here is a post init call back.

@Lindon
Perhaps you could use if(Engine.getCurrentUserPresetName() != "") to
check whether a preset is loaded. If not, load the Init preset.

Regardless of whether a preset is loaded by the saved DAW project or by your script, the post callback is always executed.

It is even much easier!

In the HISE settings you can define exactly this behavior under “Default User Preset”. Then you don't even have to script!

Might be able to do it using this - https://docs.hise.audio/scripting/scripting-api/userpresethandler/index.html#isinternalpresetload

really none of this is much use, I have a panel with some data in it - it might be empty it might not.

if its not empty I want to draw the path it describes in a panel, on init. But on init (no matter the preset you are loading) the data panel load takes longer than the init processing AND any post-load processing(so anything in your post-preset callback)....so it never draws itself...

What I'm looking for is a "proper" post init call back that accounts for any panel data load scenario...

the data panel load takes longer than the init

Could you provide more detail about what you're doing?

[Lindon]

@d-healey sure:

See that grey circle inside the XY pad? Thats a path, its held in a Panel.data object, when I load this preset the data is passed to an array and from there it gets drawn correctly in the paint routine..., but on init - it all goes too fast and it doesnt get drawn - the array holding the Panel data object = 0.....

[d.healey]

@Lindon What's the reason for storing this in the panel's data object? And why do you need a path to draw a circle, I assume there is more going on?

So its not always a circle its whatever the user draws (see the Record button in there?)- this is just one of the pre-loadable shapes.... when the user hits Play the XY pad follows this path and this modulates volume in the voices....

Every preset needs to save its own "XY path shape".

I would add an video showing you - but the forum wont let me load mp4 files.

Ah I understand now. Are you able to store the path as a base64 string? Perhaps that will speed up the loading. Do you have some method to be able to test when the loading is complete?

not really and no in that order - especially the last bit - thats where the problem is - there is no notification that the data is loaded, if there was a callback for this I could do the repaint then...

[d.healey]

@Lindon Can you make a minimal snippet I can play with? Something that just draws one of these stored paths on a panel and takes too long to load.

Well I will try and make the time to do that - but Im in delivery crunch right now.....

[Oli Ullmann]

@Lindon
Ok, if I have understood correctly, the panel is drawn before it has the correct data. Correct?

Have you ever tried a ComponentValue-Broadcaster? This then sends a repaint command as soon as the value of the panel has changed.

I think you would then have to use the value of the panel and not a panel data object...

Something like that:

@Oli-Ullmann thank - I already have a work around - what Im asking for is a post-init callback - as David did right at the start of this thread.
