will do thankx

If anyone still interested in experiments with Kotlin/Native and libui, here is very basic but working wrappers: https://github.com/msink/kotlin-libui

@msink Very nice 🙂 How complete is libui these days?

@edvin development resumed (was frozen for two years). Tables and Trees still "in next version", maybe in month or two.

@msink Interesting 🙂

I built a neural network from scratch(ish) and used TornadoFX for the training/predicting UI. https://github.com/thomasnield/kotlin_simple_neural_network

So I think recreating this in TornadoFX is going to be my next major home project, complete with animations. https://m.youtube.com/watch?v=SC5CX8drAtU#

@thomasnield Very cool! Would be interesting to see if we could create a generic UI component from your work!

There was just an issue raised on the samples project about a login screen not rendering correct on Windows 7. I'm guessing a really old JDK to go with the really old OS, but we'll see. Anyone else still running Windows 7?

Turns out the issue was an old JDK, not Windows 7 itself.

@edvin I am sure I'll be using something Gerrit built

@thomasnield Ah, I was unsure if there were any UI components that would satisfy your requirements out there already 🙂

@edvin the problem is really just finding the shortest path across all points. It just looks more useful when it is overlayed on a geographic map. I may just use the standard javafx shapes

What's interesting about the traveling salesman problem is it shows how limited neural networks really are, as they cannot solve computationally complex problems like this one. Old school operations research algorithms are still king in this space.

Hey all: quick question on JavaFX canvas. I'm probably abusing it, but I'm getting like... 15-20 FPS when I draw a bunch of images to it. It looks like all the CPU time is spent in com.sun.javafx internals.

Am I missing something?

To give you some idea of the scene that's being drawn: https://imgur.com/mQRwXXz

Are those blue things an image each?

No.

One texture.

But it would be lovely if I could just set pixels.

I mean, efficiently. I know I can use TextureWriter.

@jo are you calling Canvas.drawImage ?

@carlw No. I have a graphics context on which I'm calling drawImage.

sorry...that's what i meant

Oh.

canvas.gc.drawImage

Yes.

is the problem that the fps is not consistent? it looks like 30-40 fps in your screenshot but you mentioned 15 fps
