that

onDock

is a handy function:

override fun onDock() {
        passphrase.set("")
        status.set("")
    }

Answered the SO issue 🙂

@User uploaded a file: Project Setup Problem? and commented: Was trying to answer the SO question and started getting the following stack trace when the combobox error occurred. It must be something in my intellij project setup?

@gtnarg: Did you change JVM? Try to rebuild the project.

@edvin - rebuilt it multiple times 😞

stepping out - will look at it later...

actually - I think it's an old jdk - it's an environment I haven't used in a long while. Upgrading now...

@edvin 👏 I wish there were more such articles https://kotlinlang.slack.com/archives/feed/p1483387037000084 Otherwise it is hard to learn how you intended Tornado to be used (and why)

a small detail: is

singleAssign

in Tornado? If so, why the heck it is not in stdlib? I even can't find an issue to add it!

@voddan Someone just made me aware of that. I'll start blogging regularly to get our vision across better. I'm actually amazed of how many people have picked up TornadoFX and made cool things with it, and even though we don't force a particular way of doing things at all I'd like everyone to be aware of all the cool features and syntax sugar we have added to it. Using the best practices really makes a big difference for maintainability and readability of the code.

@edvin something to ponder for you again

When I have a treeview it is populated using the

populate

function during startup, but what if I want to completely replace the current content with other content?

Ok, found the

singleAssign

. Vote: https://youtrack.jetbrains.com/issue/KT-7180

@voddan Thomas made this one, he already knew about the issue I think, but we couldn't wait 🙂

@ron If you replace the root node you should be able to just call populate once more. I've been wanting to make that data driven though.

I am angry with the #stdlib guys, not with you 🙂

Hehe, I know 🙂

I try to never use it in UI code, for the reasons I mentioned in the blog post.

But it absolutely has it's merits.

I added a comment in issue pointing out that we are talking about

singleAssign

@thomasnield’s link points to completely different code 🙂

@edvin yeah I think I will make that another event that will call the populate again, I was hoping for a cleaner solution, as this is not the cleanest way IMHO

@ron That's because the line numbers changed 🙂 hehe

@ron Yeah, it sucks. I'll have a look at it tonight, OK?

We need to improve TreeView support.

no rush, I will do the event for now

@cypher121 I posted about tornadoFX yesterday https://ronsmits.org/2017/02/idletimerinkotlin/ I will start making small snippets like that more

I just realized why I prefer to use

Pair("selecteditem", controller.selectedEntry)

instead of

”selectedItem” to controller.selectedEntry

for me the

to

syntax feels reverted as if you are putting the key into the value instead of the other way around

if it had been

controller.selectedEntry to “selectedItem”

if would have felt more logical for me

Very nice, Ron!
