What's the purpose of the null item?

I want to be able to select and bind null 1 sec

the other items are currently String?

I have a "Contact" with e.g. Salutation that can be null. Salutation is another object in Contact. So I have a list of objects bind to the combo:

And I would like to select null in this combo box

Could something along these lines work?

@carlw I haven't read it yet, checking now 🙂

@kastork I currently load the Objects from a database and the salutations are also saved there. So I load a list of salutations and a list of contacts, then I link from the contact to the salutation. Currently that only works with Objects per table... I also don't want to add a null fake value to the observable list... In case I want to edit/add salutations I don't want to see the fake value. So my current Idea is to have an observableList connected to the observableList of all salutations that adds the null value for the combo.

@carlw I posted a suggestion on 719 🙂

i like that coarsen-ing approach that denormalizes the record in the city + street bindings

Yeah, I think the ViewModel is a good place to do that, because it doesn't require you to change your model composition.

I have several layouts, like TabPane and VBox, and so forth, which contain several CheckBox and other objects as children. I'd like to iterate through all the children and create a collection with each text attribute (e.g., a simple Map like "someText" -> isSelected). Do I need to specify a reference to each child to later iterate through, or can I do this implicitly? Would best practice be to use a Controller or a Model? I assume this is relatively simple, but am not sure of the best practice. I'm looking for something akin to the functionality of document.getElementsByClassName() in JS -- but I'd like to do this the best Kotlin / TornadoFX way. Thanks.

@Jon White You can use

Node.select()

, but it feels like you're attacking this the wrong way. I would guess the UI elements are created based on a datastructure? Couldn't you navigate the data structure instead?

Hey guys finally got around to enhance the color annotator in the tfx-plugin. Colors will now be recognized for the following expressions: -

c(...)

-

multi(c(...) | Color.*)

-

Color.*

In addition Colors will now not only be recognized in the `Stylesheet`class but in any other class as long as the class is part of a tfx project (sorry @anidotnet that you had to wait that long for this feature 😉 )

Wow @nimakro - very nice!!

@edvin Thanks, it's good to know about

Node.select()

. I agree -- I think it was the wrong strategy. I ended up moving objects into a data structure within a model object, and am now indeed iterating through that. I'm also leveraging Properties for connectivity. I've still a bit to learn about JavaFX as TornadoFX is my first exposure. Things are coming along nicely now. 👍

@Jon White Great to hear 🙂 Good luck, and we're here if you get stuck on anything!

I'm trying to let the

imageview

fit it's parent's (stage actually) size but it doesn't work for me, could someone help me?

@abhinay Maybe we should make

fitToParentSize()

work as expected for ImageView, what do you think?

@edvin Sure. I can raise a PR sometime tomorrow.

@abhinay Great! I think it's worth it, following the principle of least astonishment 🙂
