@permalmberg Actually, it goes pretty good with how the Kotlin collections work.. You have

list.get(0)

but you also have

list.first()

like selectFirst

first

have special use cases for us humans

@edvin True.

@edvin I'm using your TornadoFX guide as a refererence for learning and it is a great help. However, since I've never used JavaFx prior to this, I feel that some parts are missing. What I'd like to see added is some form of API reference linked in the guide at relevant places, For example, the CSS-section gives a good overview but if you don't have prior knowledge of both CSS & JavaFx there is a large gap to fill knowledge-wise. A specific example is the

tackyButton

style sheet where you use this:

borderColor += box(topColor,rightColor,bottomColor,leftColor)

Where does `box()`come from, and what other options are there?

Is

reloadStylesheetsOnFocus()

supposed to work on all stylesheets/components? I've got a

circle

with a stylesheet, but it doesn't get applied until I restart the app. Also, is there a dynamic way to load stylesheets so that you don't have to specify them all in the

App

-constructor ?

@permalmberg Thank you for that valuable feedback. I'll make som additions to the css chapter later today.

reloadStylesheetsOnFocus

will reload all stylesheets, but it will not touch inline styles. To update inline styles you need to use

reloadViewsOnFocus

instead. That will also update any changes to components/builders.

You can add stylesheets dynamically using

importStylesheet(StylesheetClass::class)

box

is a way to describe

top, right, bottom, left

. You can also choose to give it one argument, then it would apply for all edges. Two arguments would mean top and bottom.

Gotta run out for a bit, back in an hour.

Thanks @edvin

class DrawingSurface : Fragment() {
    override val root = pane {
        this.minWidth = 400.0
        this.minHeight = 400.0
    }

    class MyStyle : Stylesheet() {
        companion object {
            val circleStyle by cssclass()
        }

        init {
            circleStyle {
                //borderColor += box(c("#FFFFFF"), c("#FFFFFF"), c("#FFFFFF"), c("#FFFFFF"))
                fill = c("#8F008F")
            }
        }
    }

    init {
        with(root) {
            group {
                circle(100.0, 100.0, 50.0) {
                    addClass(MyStyle.circleStyle)
                }
            }
        }
    }
}

That's not an inline stylesheet is it?

Neither

reloadStylesheetsOnFocus()

nor

reloadViewsOnFocus()

makes it reload without a restart. Ah well, something to look into later today, got other things to do for a few hours.

@edvin Regarding CSS-typesafety: Applying a style with an attribute that doesn't exist on the target component doesn't generate an error. e.g.

class CircleStyle : Stylesheet() {
    companion object {
        val circleStyle by cssclass()
    }

    init {
        circleStyle {
            backgroundColor = multi(c("#8F00FF"))
        }
    }
}

applied to a rectangle runs, but doesn't apply the background color since the rectangle expects a

fill

(as does a

circle

).

You might want to put a note about this in the docs too.

@permalmberg If it doesn't reload I guess you're not running in debug mode, or you're not compiling before you switch back to the app. Both are a requirement for the JVM to see the new code 🙂

@permalmberg There is no easy fix for applying properties that have no effect on a component I'm afraid.

@edvin You're right of course. Silly me. I blame it on all the Christmas food making my brain sluggish 😛

Wrapping up Chapter 2 of Packt book on RxJava, then I'll be catching up here...

Hope you all had a nice Christmas with your families!

@thomasnield Nice! I have a couple of ideas for new functionality I'm playing with, and writing some docs in between. Will start moving stuff from the wiki tomorrow.

Cool, no worries. I got some catching up too.

I know I can override the fun stop from App but what if I want to intercept the X of the window and intercept that one?

so that the window is not closed when I press that X

a stage has a onCloseRequest

That's right @ron 🙂

@ron If you just want to prevent window closing you can do

stage.setOnCloseRequest(WindowEvent::consume)

Design question: What is a suitable container for an object/view that will be moved around on a canvas (or perhaps just a Pane with a Group inside) by the user using the mouse and/or keys? From what I've read a

Fragment

seems to be the right choice, anyone agree/disagree?
