kotlinlang #tornadofx

My dry run for OReilly webcast went well. Really looking forward to getting this done on Tuesday, and focusing on more fun documentation projects like TornadoFX and RxJavaFX/RxKotlinFX.

If you know anybody wanting a crash course in SQL, please let them know!

@thomasnield Yes. I work with a support team that is really motivated to up their troubleshooting game.

I've designed the material to painlessly teach SQL in the most pragmatic way possible. I created it originally for non-techie people, but it surprisingly has been embraced by programmers and technology professionals too.

@carlw If that's your ListCell, then you don't need it anymore, and you can exchange all of that for

cellCache { controller.readCache(it).root }

@thomasnield I'm so happy for you and the success you've had with the book and the training course. I'm guessing you can use what you've learned now as a platform for future endeavors as well!

@ron You might as well just call

controller.removeItem(currentItem)

directly from the button action in TodoListView I think.

ron

10/02/2016, 4:00 PM

I already changed that

ron

10/02/2016, 4:00 PM

not pushed it yet

ron

10/02/2016, 4:01 PM

that code was changed a lot

ron

10/02/2016, 4:01 PM

in the last week I mean

edvin

Aha, I also made a version of toggleClass that takes an observable boolean value, so that you can keep a css class toggled based on that observable boolean.

So you can now replace

currentItem.completedProperty.onChange { checked -> toggleClass(Styles.completed, checked) }

with

toggleClass(Styles.completed, currentItem.completedProperty)

edvin

Much nicer to read IMO 🙂

edvin

I'm thinking of a way that we can add editing support to ListView and friends in the same way that we provide

cellFormat

and

cellCache

I need to pull and build tornadofx for that toggleclass? cuz I am loving that one 😈

edvin

10/02/2016, 4:15 PM

@ron Yes, and a full rebuild as well, or you would get a "MethodNotFoundException" or similar 🙂

ron

10/02/2016, 4:17 PM

you know I pulled something like 2 days ago and already 85 insertions and 80 deletions

ron

10/02/2016, 4:25 PM

hmmz does not work?

ron

10/02/2016, 4:26 PM

ah wait it can be removed out of the onchange

ron

10/02/2016, 4:26 PM

(which I still need btw)

ron

10/02/2016, 4:28 PM

Copy code

currentItem.completedProperty.onChange { checked ->
                                controller.list.setPredicate(controller.filterBy)
                            }

edvin

10/02/2016, 4:42 PM

I didn't get what you meant Ron?

edvin

10/02/2016, 4:42 PM

The new feature was for toggleClass 🙂

ron

10/02/2016, 4:43 PM

the list predicate needs to be set again, the list 'recalculated' when an item is toggled

edvin

10/02/2016, 4:43 PM

This function will not help with that. But I will suggest an optimization for that later as well. Right now I'm working on the editing support.
