like this?

nevermind I fixed it:

column<DailyCategoryModel, Number>("Voice") {
                    it.value.categoriesProperty.filter{
                        it.category == "voice"
                    }.singleOrNull()?.valueProperty ?: SimpleIntegerProperty(0)
                }.cellFormat{ text = "%,d".format(it)}

This post shows some mvvm concepts https://courses.bekwam.net/public_tutorials/bkcourse_tornadofx_mvvm.html

it looks a bit like tornadofx!

Read about this today ar work!

how can I implement animation meanwhile

runAsync{...} ui [...}

is processing? For example if

list

remains to be non-pulled with data I’d like to show this with loading icon

Try a progress bar or indicator with indeterminate state; bind the visible property to the running property

Does it support custom gif?

By running property you mean function that uses

runAsync

?

i'm not sure about the custom gif. i'd just bind a progress indicator or its container to the TaskStatus object as in here https://courses.bekwam.net/public_tutorials/bkcourse_tornadofx_cancelapp.html

Okay, I see can you suggest anything with this case: if user’s sending message, it should be shown before server responded with successful status. The guy before me implemented this as “Adding object to the list with fake id, then, after server responded with success, changing it’s ids and other data with data from respond (Id’s generated by server, such as timestamp)“. Can I run it as

runAsync

with progress bar indicator?

is it possible to implement

JsonModel

on an immutable (data) class?

@chickenfresh Here's an implementation of the ProgressIndicator. I'm animating a drag down which moves the listview, revealing a Fetching banner. when the fetch completes, and event is posted that reverses the animation.

@carlw Here's the changes I made, in a slightly more readable format.

W__RuckusT_Styles.kt

@carlw just now got the time to reveal the code, another awesome snippet but question was misunderstood 😞 The Problem is not fetching, I’ll try to explain: I’m typing some text in

textfield

, on finish I press`send` button it sends

post

request to the server, which responds with generated

id

(which isn’t incremented as {1, 2, 3, 4, 5) and other details But I don’t want to wait for respond (which can take, for example, 1 second), I wanna show this message in list with others, but with some status indicator (like a progress circle on right, or if there was an issue with sending - something that indicates it). So, to show this in list with existing messages, I need to create an object, but I don’t have real

msg id

so the only solution I have is to create it with

null

id

and other fake details, after then on respond I’ll need to replace it with real ones. Actually, I hate this idea, if I’m sending

message

with turned off wifi and, for example, it takes long enough to get respond - switching views would cause in loosing this

message

i thought you might like a progressindicator example. that wasn't mean to solve the front/back-end interaction

@carlw this is awesome. Great chance to see eventbus, asyncprogress and great animation weave together like that, as those are the topics I haven't had much time to play with

@chickenfresh for the backend/frontend interaction you can use a surrogate key. pass along an ever-increasing counter that you can correlate with a later update from the backend 1. Enter the value in the textfield 2. Submit the textfield along with a counter that's unique for the current program (say surrogateKey=9) 3. Call the backend asynchronously passing the id from 2. 4. When the results come in from 3 (say with real id=10040506050), lookup the surrogateKey object 9 and apply the read id 10040506050

this is my gist for a surrogate key

@carlw yes I could but it’s not supposed to show progress, only status

@amanda.hinchman-dominguez upvote

@carlw why can’t I use

when

in, for example,

center = when (something) { is ... -> {<one graphical object>} is... -> {<another>}}

?

in

MainView

root

something

should be binded property?

are you using a sealed class for the something?

var curSelectedChat = SimpleObjectProperty<ChatViewInstance>()

ChatViewInstance

is sealed class I’m trying

center = when (curSelectedChat.value) { is ChatViewInstance.Test -> label("test") else -> label("another test")}

else is working
