callback seems to be the only sensible option

but i guess mouse move events could also have info on them if there is a drag and where it started

i guess this would still nto be good enough to get very fine relative drags without implementing some tracking yourself.. but most püeople will nto need it anyways

@Nikky I added simple API for dragging. You can try it - https://github.com/xal/data2viz/tree/events.

cool

Usage & API

Any feedback will be helpfull

Interesting…

Hey 👋 Is there a way to size an element based on screen size? So for example I could have a rect that takes half of the screen.

Hi @Fudge, The strategy to use depends on your visualization and platform. It’s challenging to have a solution that meets every case. For instance, on Android, you would use all the screen size but should decide how to adapt to a rotation of the screen. Are you going to apply a ratio to the whole viz to fit in the screen or are you going to clip it? In any case, it’s possible on all platform to get the size of the containing window. You can then set the viz to that size and draw a rectangle of half the width.

is there any release planned ? since 0.7.2-RC1 is quite old by now and still does now contain events or maybe a sample of how to use jitpack with d2v if possible ?

btw i tried to check out the project and run

./gradlew publishToMavenLocal

but that fails with error like

Could not determine java version from '11.0.2'.

ande even after fixing those (gradlew wrapper older than 5.0) there was errors from actual defs. missing in some modules and it just.. failed

Hi @Nikky, I’ve been exhausted by switching from too many projects. I had to focus on fewer ones, and data2viz suffered from this. It’s better now, and I can go back on the project. I will release a new version this week and have a look at the

publisthToMavenLocal

problem.

well i just ran into some really weird crash with glyphcache or so? https://gist.github.com/NikkyAI/809525ed3466ec8ea179019dd3c41a2a

i started playing with

PathNode

, i did not figure out how to move one around, os instead i just clear the path and redraw it when stuff resizes or pieces are moved at least the rescaling and clearing seems to work fine on first glance but sometimes that exception throws and the whole jfx window goes funky it could alos be a sideeffect of updating to 0.8.0-RC1 ofc and this is completely unrelated to paths i also use some utf8 geometric symbols in strings now, could jfx have a issue with rendering those ?

i think it was utf8 characters after all, i ended up using them in their written long form instead

Hi @Nikky, I did the release yesterday, but didn’t have the time to notify you. To use events you have to call in the context of a viz:

//add event listener
		val handle = on(KPointerMove) { evt ->
			println(evt.pos)
		}
		
		//remove event listener
		handle.dispose()

yeah i have that all figured out, i used the event branch before and after that just the names changed

the previously mentioned thing, game, gui etc.. its going somewhere: the left side is all koolui, i am using PathNode.path.svgPath, then stick some extra string on there and then use koolui's svg image handling to draw the player shapes on the left all kinds of sizes do not quite match and the rules as website also do not look great.. but its going somewhere multiplatform also the other "tabs" are the default tests i left in

btw koolui is thanks to @josephivie its a far shot from perfect, but it gets me quite a lot further than i initally thought

@Nikky and the right side is what?

data2viz @gaetan

eventually it would be even nicer if i can embed data2viz in koolui, but i am not sue if all things will even be supported, like mouse hover and drag events might be hard

I’m not sure of what you will gain using it. It depends on the number of widgets and interaction you need. I would start a first version in plain JavaFx for exemple, to be sure of the UI design, before trying a complete multiplatform version.

@gaetan turns out you can do a lot with it and writing new components and widgets that are made up of others is easy this is my game in html, the jfx version looks even better this is with data2viz canvas added as a koolui component, so i can have it wherever

later i will add more d2v views that have preset games with visual annotations like arrows and popups for people to learn the game and rules

🎉👍

Thanks for the info.
