edvin
08/26/2017, 7:11 PMWe could make it as simple as this: - e
edvin
08/26/2017, 7:11 PMfun EventTarget.addChildIfPossible(node: Node, index: Int? = null) { if (FX.addChildInterceptor(node, index)) return - e
edvin
08/26/2017, 7:11 PMThen let it be possible to install an addChildInterceptor that would replace the default (which always just returns false) - e
edvin
08/26/2017, 7:11 PMAny objections or better ideas? - e
edvin
08/26/2017, 7:30 PMThe name sucks. - e
edvin
08/26/2017, 7:31 PMWe need a better one. It's an interceptor that can veto the
call, which is used by the builders to add children to their parent.addChildIfPossible - d

08/26/2017, 7:32 PMLooks good to me. - e
edvin
08/26/2017, 7:33 PM@devanand I can add it, then you can try it to see if it works for you. If it doesn't do what you need it to, we'll rethink and remove if needed. - d

08/26/2017, 7:33 PMSure. - e
edvin
08/26/2017, 7:34 PMThis would be the default: - e
edvin
08/26/2017, 7:34 PMvar addChildInterceptor: (parent: EventTarget, node: Node, index: Int?) -> Boolean = { _, _, _ -> false } - e
edvin
08/26/2017, 7:41 PM@devanand You can try something like this: - e
edvin
08/26/2017, 7:41 PMFX.addChildInterceptor = { parent, node, index -> if (parent is MigPane) { parent.add(node, CC()); true } else false } - e
edvin
08/26/2017, 7:42 PMAdded now, even with documentation 🎉 - e
edvin
08/26/2017, 7:57 PM@devanand I'm publishing a snapshot to Sonatype now. - e
edvin
08/26/2017, 7:59 PM@devanand Check it out and let me know how it works for you. - d
devanand
08/26/2017, 8:05 PMThat's awesome - d
devanand
08/26/2017, 8:05 PMI will try it - d

08/27/2017, 12:55 PMHi, I want to send a model instance (which is bound to an ItemViewModel) as payload in a POST call whenever the property inside the model changes. I have the following setup:Copy code
Butclass MainControl : JsonModel { val controlProperty = SimpleDoubleProperty(0.0) var control by controlProperty override fun toJSON(json: JsonBuilder) { with(json) { add("controlValue", control) } } } class MainControlModel : ItemViewModel<MainControl>() { val mainControl = bind(MainControl::controlProperty) } class MainController : Controller() { private val api: Rest by inject() private val control: MainControlModel by inject() init { with(api) { baseURI = "<http://localhost:8090>" } control.mainControl.addListener { _, _, _ -> LOG.debug("{}", control.item) <http://api.post|api.post>("control", control.item) } } }
is always null? How can I do this?control.item - m

08/27/2017, 1:31 PMI want to implement the following scenario: whenever a sliders value is changed, the value gets sent to a backend component via a REST call. - e
edvin
08/27/2017, 1:32 PM@matthjes You'd have to either make the mainControl property autocommit, or you have to commit the model when the slider changes. - e
edvin
08/27/2017, 1:32 PM@User uploaded a file: Make mainControl autocommit on change - e
edvin
08/27/2017, 1:33 PMThe alternative would be to listen to changes to the valueProperty of the slider and call model.commit, possibly by passing it just the mainControl property if you just want to commit that. That kind of defeats the purpose, so it looks like autocommit is what you want. - e
edvin
08/27/2017, 1:33 PMHowever, you still need to set an item into the viewmodel, it doesn't magically get filled with an instance of MainControl. - e
edvin
08/27/2017, 1:34 PMIf you want your ViewModel to always contain an underlying item, you can add one in the ViewModel constructor: - e

matthjes
08/27/2017, 1:35 PMAh, this looks good 🙂 I've already added an instance of my model to the constructor of the ViewModel, but I did not commit the change.
