The model layer contains the UI-agnostic validations, data access, and business logic. ViewModel adds in FX property objects and sets up data binding.

Is there a way to leverage the tfx dependency injection stuff with things that arent models, controllers and viewmodels... My own classes for instance? Instead of using another DI system?

Good morning. I'm trying to figure out CSS and TableView today. I'd like to hide the table header so that I can align a child table via rowExpander against the parent. Is this possible? Finding it hard to understand how to create the stylesheet

@sp33dy You should look up the JavaFX 8 CSS Reference so you get a better understanding of how the TableView is actually realized. On top of that, use the built in Layout Debugger or Scenic View to inspect your scene graph. This will help you a lot, as you can also see what classes are applied to what elements. This makes targeting stuff with CSS much much simpler.

many thanks, will start reading

Oh wow, that's simple too! Thanks @edvin. I much prefer to be pointed to and then figure it out. Header now gone 🙂

Great 🙂 Better than giving you the exact selector you need, now you know how to address almost any CSS issue 😁

exactly, just need to walk the path as it were

one question though

in the Javafx references I've found.. I see a lot of things like: -fx-table-cell-border-color

these appear to be constants or fixed values

do they exist in Tornadofx? i.e. to get the default cell color etc

-fx-background-color: -fx-table-cell-border-color, -fx-background

for example, the above is setting a style fo the background colour and seems to be picking the table-cell-border-color and then the background

I think you have to use

unsafe()

to set those, but @Ruckus would know for sure 🙂

Actually, I've now discovered that I have to add lots of strange code to make the rowSelector table shrink to the number of rows (because there isn't a method to set prefheight to say 5 rows; which is what I want to do). Instead, I'm going to abandon rowSelector and see if I can build this in one table and add my own controls in the rows to alter the table list on the fly. In that way, it'll do exactly the same as i want, but in one table. I need the columns to line up, so this might actually be easier and cleaner

My assumption is that I can add buttons into a table cell

yep, button added.. So just need to show the hidden rows into table when button clicked 🙂

Hi, did anyone make something similar to a SnackBar or a Toast (this is a thing in Android and Material Design) using TornadoFx?

@louiscad Not in TornadoFX but JFoenix has a snackbar control - https://github.com/jfoenixadmin/JFoenix/blob/master/jfoenix/src/main/java/com/jfoenix/controls/JFXSnackbar.java

How on earth does one chain a few ui calls together? i.e. I need to expand a treelist item and then put it into edit?

to put some context. I have a contextmenu item to 'add' a node. It only works on a directory (disabled when a file item). If I select, the result I would like is to add a node to the tree and then instantly put it into edit mode

I can add the node and I can force it into edit. BUT, I can't do in a sequence. I figure the UI doesn't complete the first task for the second to be carried out.

...and don't start me on scrollTo().. AS I can't fathom that out 😞

This is as close as I can get. If the treeitem is already expanded, the item adds and is selected

I dislike this runAsync and wondering if I'm using incorrectly?

actually, i might just show a popup and have done with it. Do it there, update tree when done and there is then no need to try to manipulate Tree. However, I'd love to know the strategy for this

yeah. that's not right. you will nest runAsync's sometimes but only if you have to gather input from the user in the middle of long-running processes

first, no UI-modifying code should ever be in runAsync since it's off the FX thread
