That section looks much better. Robert is going to go through it this morning

Haha, good timing! Let me know if he finds any incoherent ramblings in there!

@edvin robert found a problem in the code snippet i wrote up in #59 on the guide. i can get to this later tonight if someone doesn't beat me to it

How to do that simple thing

observableMeasurements.forEach { type, measurements ->
            linechart(type, CategoryAxis(), NumberAxis()) {
                series("Sensor") {
                measurements.forEach {
                data(it.timestamp.toDate(), it.value)
            }
        }

or how to put Map like FXCollections.observableHashMap<String, List<Measurement>>() in listview? Or just put data in List<DataHolder>?

@iLobanov i can look at your example later. in the meantime, here's a plain JavaFX post on LineChart

@edvin ^ always looking for an opportunity to feature oscilloscopes (see the SlideShow app a page down from the LineChart docs)

@carlw thx for usefull link!

Solved, bindChildren() is my solution)

Can someone help me) How to setup display date format for datepicker?

Specify FULL, LONG, MEDIUM, or SHORT

@iLobanov or do you want to specify something like ISO?

ISO conversion back-and-forth

People, what do you think about initial binding direction? Is it OK or strange, expected or not?

@carlw thx again for your help)

And what best way to get timestamp of picked date from dateFromProperty passed to datepicker?

java.sql.Timestamp?

or timein millis?

Just saw this... https://developer.apple.com/macos/whats-new/ "Deprecation of OpenGL and OpenCL"

iOS too... https://developer.apple.com/ios/whats-new/

yeah. i'm not up on what will replace it

Sucks mainly for the Gluon guys right now? I'm pretty sure they leverage it for their iOS stuff.

and a lot of ios developers too

How to make listview( or gridview) with items, which childs will be selectable on the top lvl? Actually how to provide selected state to vbox or any other component?

You should look at ItemViewModel as well. This is the basic selection scenario. Create observable member variables for your data (“drinks”) and the selected item (“selectedDrink”). Bind these values to the UI. In your action handlers, reference the member variables.

The snippet also has a use case for adding items to the list. It’s the same process. Create a member variable representing the newItem. Bind the newItem to the UI. In the action handler, reference the list of values and the new item.

@ccrowe I see. And one more question what kind of property I'm should declare in object to pass it in bindChildren() function for some reason next variants did not working

val sensorsProperty = SimpleMapProperty<Int, SensorEx>(this, "sensors", sensors?.observable())
var sensors by sensorsProperty

val obsSens = FXCollections.observableArrayList(sensors?.values)

sry get slepy just missed curve braces this one works bindChildren(project.sender.value.obsSens)

Here’s an example with objects. You’ll use objects in the itemsProperty and an ObjectProperty to hold the selection. I’ve added a control to gather up a pair of values in an add operation to form a SensorData object
