But i don't think its gradle specific issue seems more like the IDEA issue

I find the Maven/IntelliJ connector to be the most reliable.

@g4sarma You've refreshed the project, correct?

sometimes gradle in intellij doesn't like to update dependencies until you refresh the project

I feel like I need a course just to use gradle

@g4sarma while importing a gradle project in IDEA always tick the "auto import" check box. That will help you to download the dependencies instantly. In your case, you can delete the ".idea" folder and any ".iml" file and try to open the gradle project again and don't forget to tick the "auto import" checkbox. If you are behind any corporate firewall, don't forget to set the proxy details as well.

oh yeah

that's super important

screwed me over for a while when I was first learning gradle

Hey all! Is there any good example how to use ItemViewModel with treeview?

@edvin I want to inject

A.class

inside

B.class

. Since I want to use

A.class

multiple times, I have created it as a fragment. So how do I inject

A.class

as a fragment and use A class' text field in

B.class

@ajithprasaad You can either use a Fragment or use a View with Scopes for this. You shouldn't "use A.class' text field in B.class", you should only share model state between the views, ie. manipulate properties of a shared ViewModel.

@iyankovsky Do you want a single ItemViewModel per row in the treeview or do you just want to bind the selected item to an ItemViewModel?

@edvin I want a single ItemViewModel per row

@iyankovsky The TreeView isn't really data driven, so the given item will never change for a given TreeItem. If you supply a custom TreeItem to the builder you can wrap the item in a ViewModel in the constructor of the custom TreeItem. Does that make sense?

@edvin Yes, it does. Thank you 🙂 I just thought it works similar to tableview

@edvin I too am in need of using scopes to be able to use 2 controllers with 2 views, all connected to each other

I am not necessarily recycling views, but will be choosing what data to use based on a selection choice

@amanda.hinchman-dominguez uploaded a file:

I hope I worded what I'm trying to do well enough; I read the documentation and have a couple questions about scope:

1) I see you can use scopes from controller to view - Can scopes be used controller to controller? Or view to controller?

@amanda.hinchman-dominguez uploaded a file:

2) The above example provided in the documentation shows an example of using an object class with what looks like a scope in the function applied to a model class. What does setInScope do exactly? I would think that if you were to set the scope, it would make sense to refer to the scope in the model class and set the scope there

3) Can you provide a basic example of a view to controller scope?

@amanda.hinchman-dominguez Scopes in TornadoFX grew out of an MDI requirement I had with a client. That's Multiple Document Interface termed from my work WAAAY back as a Microsoft Foundation Classes C++ developer. You can think of it as multiple instances of the same view (same screens / different data). A familiar example would be several IntelliJ windows each showing a different project. Usually, you'll divide your app into Singletons and Prototype or Instance-scoped objects. There's only one Singleton object in an app like a model component that issues calls to a RESTful web service shared among many views. There can be many Prototype objects in an app, say a pair of details popups each one showing different data, but launched from a common table component. Scopes were needed for what I was working on because there were many collaborating views and each view needed to be paired with the correct model components. In this case, there weren't Singleton model components since each distinct window was its own app. The scope provided a way for the code to treat the injections as Singleton from a programmers perspective, but the injection would be tuned to the specific window instance.

Hmm, it sounds like I will also need to scope outerview to inner view as well - I also plan on outerview and innerview share a controller where a datagrid and the innerview interacts with each other. Does it matter which way you scope to, or is scoping bilateral?

Can you bring up multiple instances of the entire app? Including top level menus, etc

sorry, what exactly are you asking for?

If you're deciding about scopes, think in terms of windows and not components. I use the opening of main windows as the establishing of a scope.
