Perfect! I added it now.

How to create

TaskStatus

(for

runAsync

, several simultaneous tasks)? Can I just

val status = TaskStatus()

? Or I need to use scopes?

@alexp11223 No, you can just create TaskStatus objects like that, no problem 🙂

@edvin Do you think the task code would be neater to kick of several threads and Thread.join before exiting the call()?

Was it a requirement that you join or do something when all of them are complete? If so, I think coroutines is the easiest solution. Hopefully Kotlin coroutines will be in Maven Central soon.

Then I'll add support for it in the framework.

don't know. i read several simultaneous tasks and was thinking that they could all be kicked off in one task call then pulled together with a Thread.join. that way, they can all exit at the suceeded

Depending on the use case that sounds very nice.

if I have a string property

val programCodeProperty = SimpleStringProperty()
    var programCode by programCodeProperty

and control with

ObservableValue<String> textProperty()

is it possible to bind to it? (2-way) I saw that there is

stringBinding

extension function, but I am not sure how to use it

@alexp11223 are you binding programCodeProperty to a UI control's textProperty?

(I knew Carl would catch that one :)

yes

Are you sure the control's textproperty is defined as

ObservableValue<String>

? That's not writable.

ah, yeah, I guess it's supposed to be not writable... there is

replaceText

function that is used in all examples to fill the control

What control is this?

If you really want a two way binding, you'd have to use listeners.

programCodeProperty.onChange { richText.replaceText(it) }

and

richText.textProperty().onChange { programCode = it}

That should be safe because change events should not be emitted when the same value is set.

yeah, but it still calls

replaceText

every time (when typing a letter, etc.) which is probably not ideal because it causes recomputation of things like syntax highlighting. This is probably better:

viewModel.programCodeProperty.onChange {
            if (it != inputArea.text) {
                inputArea.replaceText(it)
            }
        }

Wouldn't that still trigger for every typed letter (I thought that was what you wanted even) 🙂

@edvin i've seen a timer go into listeners like you wrote so that it's not firing so much

@carlw Smart, if you don't need real time updates.

@edvin you might want the user to finish typing a word for example

I wanted to have always up-to-date

programCode

but also to be able to replace text like this:

programCode = newCode

oh, Idea shows some warning about platform type and nullability when creating properties as suggested in guide

val fooProperty = SimpleStringProperty()
    var foo by fooProperty

without explicitly specifying

foo

type:

val fooProperty = SimpleStringProperty()
    var foo: String by fooProperty

I know, but I've never run into any issues with it. Didn't want to add boiler plate unless it creates problems.

I'm adding overloaded

action

functions which aren't passed the

ActionEvent

, so that you can bind it to function references.

Instead of

button("Save").action { person.save() }

you should be able to write

button("Save").action(person::save)

.

Hmm.. maybe that will be problematic. How will the compiler know which version you're using when you pass it a lambda?
