Opinionated JavaFX 8
Speaker: Adam Bien
How to build an app with Java FX? WYSIWYG or manual hacking? How to integrate with Java EE backend? What is a Presenter, Controller or a View? Do we need data binding?
In this virtual session I would like to introduce you to Java FX 8 from the application perspective with focus on structure, architecture and (software) design.

17:09 <justjavadevelope> lol
17:09 <radcortez> hi guys
17:09 <Guest64796> I do not hear anything and to the left I only see a window with ‘Now I have a problem factory’ (I clicked on ‘Live Session)
17:09 <sjmaple> hmmm, try a refresh of the page if you’re having problems – let me know if you’re still having issues now
17:10 <slaskawi> Surendra: https://java-champions.java.net/
17:10 <Handir_> Try the Youtube Stream: https://www.youtube.com/watch?v=W-ezZqeGQ6Y
17:10 <theotown> Try refreshing the page
17:10 <carljokl> I am hoping to use JavaFX potentially as a cross platform UI api for Open Wonderland if it is practical to do so
17:10 <carljokl> Or at least a subset of it
17:10 <Guest64796> I look at youtube. thank you!
17:10 <Marcszy> Already shared, hoping to have 4 joiners within the weekk.
17:10 <carljokl> Birthday…will there be cake……iBake….
17:10 <Marcszy> *week
17:10 <lawpro> any body having audio problems?
17:10 <Marcszy> no, I’m good
17:10 <FatLorenzo> audio works perfect for me too
17:10 <carljokl> I have good audio
17:10 <radcortez> hum adam face is covered with the hangout faces 😛
17:11 <sjmaple> Guest64796: ahhh, probably an older cache… maybe this link will be better- http://virtualjug.com?no-cache
17:12 <sjmaple> radcortez: hmm, I wonder if that’s something I can change here…
17:12 <gravadlax> yep
17:13 <gravadlax> go away faces
17:13 <theotown> I saw “feces” at first. Mini freakout avoided…
17:13 <justjavadevelope> adam, maybe move 30cm to your right!
17:13 <radcortez> lol
17:13 <gravadlax> sometimes we can see his eyes
17:13 <carljokl> Censorship…reminds me of Mike on Monster’s Inc
17:13 <theotown> I’ll be leaving soon folks, that might help!
17:15 <Marcszy> yay!
17:15 <carljokl> Yay
17:15 <gravadlax> wooo!
17:15 <carljokl> Video has cut out for me
17:15 <FatLorenzo> oh 🙁
17:15 <Marcszy> me too
17:15 <gravadlax> lost here
17:15 <carljokl> Did it for anyone else?
17:15 <Handir_> me too
17:15 <lawpro> yep yuep
17:15 <jshickey> me too
17:15 <gravadlax> +1
17:16 <gravadlax> Somebody reboots Hangouts
17:16 <carljokl> *kicks the box*
17:16 <sjmaple> trying to reboot now
17:17 <carljokl> What we need is some kind of Champion to save the day
17:17 <carljokl> I see Simon
17:17 <huxendupsel> ok is see simon
17:17 <lawpro> where is Adam?
17:17 <vasouv> can see and hear
17:18 <slaskawi> sjmaple: Yes, we can
17:18 <FatLorenzo> jepp
17:18 <jshickey> can hear and see
17:18 <justjavadevelope> yep
17:18 <dennisk1718> see you
17:18 <huxendupsel> reboot was good,
17:18 <rarchibald> Can see and hear
17:18 <dennisk1718> still ugly as ever 😉
17:18 <gravadlax> 🙂
17:18 <huxendupsel> 😀
17:18 <carljokl> Not that you are bad to look at or anything
17:18 <carljokl> But…JavaFX
17:18 — gravadlax is preparing diner
17:19 <huxendupsel> click, click sounds promissing
17:19 <gravadlax> no pressure… only 50+ people watching
17:19 <keuleJ> take it easy
17:19 <FatLorenzo> when he’s connected again his javafx app is fully implemented;-)
17:19 <keuleJ> these things happen…
17:20 <Surendra> I can hear and see you Simon
17:20 <carljokl> How long is this session by the way?
17:20 <amorfis2> It’s _virtual_ JUG, so it can always happen.
17:20 <huxendupsel> make a pone call 😀
17:20 <keuleJ> maybe call an IT guy 😉
17:21 <carljokl> I don’t know if anyone is interested in coming to my session afterwards
17:21 <carljokl> It is a bit niche interest though
17:21 <gravadlax> skype?
17:21 <manocha_ak> joined late… looks like I havent missed anything???
17:21 <FatLorenzo> which session @carljokl?
17:21 <sjmaple> we’re back – few!
17:21 <justjavadevelope> whats ur session about carl?
17:21 <carljokl> http://blogs.openwonderland.org/2014/08/17/mobile-strategy-community-meeting/
17:22 <carljokl> I am talking about the future of Open Wonderland particularly developing new mobile clients for it
17:22 <carljokl> I would actually like to use JavaFX APIs for cross platform UI if it is feasible to do so.
17:23 <carljokl> I am not sure if licencing restrictions around using JavaFX might prevent creating my own implementation
17:23 <carljokl> Especially given Oracle vs Google lawsuits
17:23 <keuleJ> Nice to see you Adam!
17:24 <amorfis2> @carljokl JavaFX was meant for cross-platform, but I don’t know if this ideas are implemented.
17:24 <sjmaple> carljokl: Adam might know, I’ll ask at the end
17:25 <manocha_ak> javafx is being supported on MAC Windows and Ubuntu 10+ as I know
17:25 <carljokl> That is why I favour JavaFX
17:25 <carljokl> Sun originally designed it to “Run across all the screens of your life”
17:25 <hendrikebbers> there are ports for Android and iOS: http://javafxports.org
17:25 <carljokl> Therefore it was designed to be platform / device agnostic
17:26 <carljokl> Cool
17:26 <carljokl> Worth considering
17:26 <FatLorenzo> and also for iOS via RobotVM as far as I know
17:27 <carljokl> No lawsuit problems or cease and desists?
17:28 <psychollek> I wasn’t listening enough, but is this injector part of afterburner ?
17:29 <hendrikebbers> yes
17:29 <manocha_ak> why view needs to have more than one controller ? are you hinting toward single page app?
17:29 <manocha_ak> dektop app*
17:29 <huxendupsel> is there a mechanism in javafx, which layouts the gui pixel independent, so that changing the screen size doesn’t have any impact?
17:30 <psychollek> at least in 1.0 you could use svg for layouting 😛
17:30 <carljokl> I guess it never hurts to “Consult the Oracle”
17:31 <sjmaple> that sometimes hurts the most 😉
17:31 <carljokl> Ok true
17:31 <carljokl> They might try and sell me Exadata but I really can’t afford one anyway
17:32 <vasouv> well that’s why my single controller is huge, 3 different panels but one controller to rule them all…
17:32 <sjmaple> mwahaha
17:32 <vasouv> i’ll follow the multi-controller notion
17:34 <keuleJ> yes, does javaFx support HiRes displays?
17:34 <hendrikebbers> Mac Retina is supported
17:37 <sjmaple> any other questions at the moment?
17:39 <keuleJ> did you ever have problems in your project with the xml-handling?
17:39 <keuleJ> e.g. did you have to edit the xmls by hand ?
17:40 <hendrikebbers> you can use sceneBuilder
17:40 <keuleJ> and no way to mess it up? so that you have to “repair ” it?
17:45 <manocha_ak> slightly offtopic may be… so how to go about using javafx with afterburner in an alreay existing swing project?
17:46 <hendrikebbers> JavaFX provides a component called JFXPanel. You can add any JavaFX scene graph in a swing app by using this wrapper
17:47 <tocsa> That archetype is great
17:48 <carljokl> I will probably need to sneak off soon
17:48 <carljokl> *sneaking*
17:51 <amorfis2> From JavaFX you create executable file, right? Can you also create an applet, and embed it on html page?
17:52 <amorfis2> (Actually, I _know_ you can embed it, but is it really an applet? Or smth else? )
17:55 <FatLorenzo> what does ::add mean – I’ve never seen it in Java code before
17:56 <sjmaple> it’s a method reference
17:56 <amorfis2> Java 8 feature
17:56 <sjmaple> can be used in lambdas
17:56 <sjmaple> Check out some of our previous sessions afterwards to see more about them… I’ll find a link
17:56 <FatLorenzo> ah ok – I’m a poor guy I’ve to use Java 1.4.2 at work
17:57 <FatLorenzo> thanks
17:57 <keuleJ> @FatLorenzo: not even Java 5?!
17:57 <sjmaple> http://virtualjug.com/project-lambda-functional-prog-constructs-and-simpler-concurrency-in-java-se-8-by-simon-ritter/
17:58 <FatLorenzo> @keuleJ hopefully beginning at October
17:58 <keuleJ> We have Java 7 for Client and Java 6 for Server
18:00 <amorfis2> @FatLorenzo I once worked for an African bank, and I can’t imagine more rigid institution. But we used java 6 there. I wonder where do you work…
18:00 <FatLorenzo> that’s the reason why I’ve joined vJUG to learn new fancy things 😀
18:01 <FatLorenzo> the reason is the platform which I’m developing for is java 1.4.2 based and the vendor has it’s own jvm implementation
18:01 <keuleJ> Is it no Problem to create JavaFx components on otther threads than the javafx application thread?
18:01 <sjmaple> mmmm, IBM 🙂
18:02 <FatLorenzo> almost SAP
18:02 <sjmaple> close enough 🙂
18:02 <FatLorenzo> lol
18:03 <lawpro> would the code for the hack be avaialble somewhere?
18:04 <sjmaple> any other questions right now?
18:05 <amorfis2> Can you embed JavaFX on html pages?
18:06 <amorfis2> Is it an applet then?
18:06 <vasouv> how are the properties files used? let’s say read values instead of the user inputting them?
18:07 <dennisk1718> any thoughts on JSR 365
18:07 <tocsa> Starred the github
18:08 <sjmaple> https://github.com/adambien/afterburner.fx
18:10 <Struppy> What is needed on the Client to run JavaFX in the browser?
18:10 <amorfis2> So you can control DOM elements from JavaFX app? Ok, but JavaFX scene is not DOM element, is it? So how can you show it?
18:11 <dennisk1718> CDI
18:13 <sjmaple> hah, thanks dennis 🙂
18:16 <dennisk1718> Thank You
18:16 <sjmaple> np, any final questions?
18:16 <keuleJ> Everything singleton:
18:17 <keuleJ> You could have multiple tabs, which show the same view
18:17 <keuleJ> with different data
18:19 <JonasHavers> Do you have any suggestions for creating responsive layouts or a responsive design in JavaFX applications?
18:20 <keuleJ> @JonasHaves: good question
18:21 <Struppy> As far as I saw the JavaFX plugin in the browser is an applet. Is this correct?
18:21 <keuleJ> Is JavaFx the right tool for writing enterprise applications with lots of forms and tables?
18:23 <JonasHavers> @Adam: No, never asked it before 😉
18:24 <sjmaple> :
18:24 <sjmaple> 🙂
18:25 <JonasHavers> Thanks @ sjmaple for asking!
18:25 <vasouv> very nice session, thank you 🙂
18:25 <dennisk1718> Thanks again
18:26 <Milan> Great presentation. Thanks!
18:26 <huxendupsel> thank you it was great
18:26 <sjmaple> thanks for joining everyone!
18:26 <tocsa> Lots of info to interpret on my part
