@ustk @Christoph-Hart Could this be the cause of the issue?

@d-healey I don't think so. In fact I had it working and I can draw anything like an ellipse for instance. But I stopped because I don't know how to draw a path which I thought would have been more trivial...

In fact I'd like to put a path in the data property so we don't need an image. I have made pretty much all the necessary modifications but got stuck at one point and I don't have much time atm.

This gives an idea if you want to give it a go:

@d-healey In the end it would be even better if we can set a path from API like FloatingTile.setPath(path) but that would be even harder to implement. So placing it in the data property might still be a good workaround, but not a conventional one I confess.

[Christoph Hart]

@ustk It won't work like that. The load path from data expects a consecutive memory block of 8bit integers (char or uint8) and the var type is much bigger so casting a pointer will make it interpret garbage.

If you're converting the path with the SVG converter in HISE you also get the ability of using a Base64 encoded string instead of the number array (which is recommended anyway because it will be shorter so the Javascript parser has much less to do in the onInit BTW). With this string it could work, then all you need to do is to create a MemoryBlock and parse the Base64 string

var propertyFromJSON("2124.dlaklasdf8laksdjh32fkaldshfasjdfsfd");
    
String funkyPath = propertyFromJSON.toString();
     
MemoryBlock mb;
mb.fromBase64Encoding(funkyPath);
    
Path p;
p.loadPathFromData(mb.getData(), mb.getSize());

otherwise you would have to convert it to a new Array<uint8> manually by iterating over the Array<var> and push each value after casting it to a uint8. Then you can use Array<uint8>::getRawDataPointer() to get a pointer to the byte-aligned data for the path.

@Christoph-Hart awesome! I'll give this a second chance then :)

[ustk]

@Christoph-Hart Alright so I'm trying this direct approach in the paint routine to "get more chance" but I feel idiot it does not work...

Maybe I need to scale the path... Please bring me to school Chris :)

Oh wait I almost got it to work! I forgot to scale the path in the resized function...
But it looks a bit weird for now so stay tuned

[ustk]

Gotcha!

@ustk @Christoph-Hart If interested, I posted an efficient, working and configurable MIDI indicator widget a couple months back.
