Neat trick to toggle between views: Use the empty state of the viewmodel as a toggle: https://github.com/edvin/tornadofx/issues/600

override fun updateModel(json: JsonObject)

so why exactly does TornadoFX include another implementation of JSON support when it could just use one of the existing rock-solid implementations?

I am trying to make a responsive tilepanel with responsive images by ´fitToWidthProperty().bind(halfStagewidth)´. My first thought was something like

val halfStagewidth = SimpleDoubleProperty(primaryStage.width/2.0)

, but the required type is

ObservableValue<out Boolean!>!

, any ideas?

@jkbbwr It probably is missing some listeners to support direct manipulation like that. I don't have time to look at it now though, can do it tomorrow, gotta run!

I'm trying to compile against the latest Kotlin plugin to see if that helps.

@kastork I think I've done several, this is one of them:

I'm almost done, it will be up shortly

I'm going to make an errand run and I'll probably need to upgrade on here but I'll be back on tonight

The bind() function registers change listeners on the Observable which is the bind target. The Observable has a reference to the underlying list. For example, bind() to an FXCollections.observableArrayList() might be based on a java.util.Collections list. Memory leaks can definitely be a concern with listeners. It's in the documentation. So, you should be using WeakInvalidationListener to provide a way for the JVM to resolve conflicts where there is a bi-directional relationship. "Weak" flags one side to give way to the conflict. It's standard in languages like Objective-C. bind() isn't a concern if the binding is going to persist for the life of the app. Where is might be an issue if you are binding from one temporary window to objects in another temporary window bi-directionally such as trying to keep the two in sync. In these cases, you roll-your-own binding by adding a change listener that will explicitly be removed or automatically removed with a WeakInvalidationListener. You might find this post of interest on the topic. http://bekwam.blogspot.com/2015/08/invalidationlistener-not-called.html

Could this be related? https://github.com/TestFX/TestFX/issues/432

@kastork Disregard, I confused myself 🙂 Checking a theory now.

@abhinay as?

TornadoFX has some TextField format that only accepts numbers?

@Carlton Whitehead @kastork Thanks guys 🙂 I'm sick, so just checking in. Should I merge the PR now or wait?

Unity does a pretty good job with that sort of thing, but I find the UI very hard to look at because they don't allow you to adjust the size of things any larger than 21 year old vision.,

@carlw @edvin @nimakro yes I am planning on coming. I am working on my proposal right now. I'll come whether it gets accepted or not.

I still have a ton of refactoring to do but I'll have to take an objective look once it's all done. Next update to my github repo will include automatic resizing for dropping tiles onto large grid tiles

@jmmk You can detect a click on the tableview and deselect if there is no item in the row below the cursor, or if the cursor is not over a row. To allow blank rows to be selected would be bad though.

@BenjaVR @r4zzz4k Absolutely. We could even merge this library with TornadoFX when it matures. This could be a killer feature to have by default.

Is TornadoFX using internals to get type safe css to work?

I've created the TornadoFX organization, so we can start moving projects in there. Suggestions for project name for the material design project?

@nimakro any chance you can put the code into the personal repo which will eventually be moved into the discussed incubator organization?

Tried that, got skin from service provider stylesheet and color from my own (I assume app stylesheet overrides service provider one). I didn't expect this to work, so I just want a confirmation I'm seeing proper results :)

It looks like I'll finally get around to making a TornadoFX Database sample app 🙂 Will work on it this weekend.

I realize now why people ask about databases. You need to decide about how to control the life cycle of connections and transactions, and the framework doesn't provide you with any support here.

@chrbongardt For that reason I always prefer to use JavaFX Properties in the domain objects. Not doing so is simply fighting an uphill battle against JavaFX itself.

Did you guys see the image I uploaded of the DB Activity Indicator? I think it doesn't show up because the storage for the slack space is used up.

Somehow, iteration in datagrid is causing the following output for 44 objects:

I'll be looking into the source code to see how datagrid is iterating through these objects, but I'm wondering if a property in datagrid could be affecting iteration somehow? i.e.

maxCellsInRow=2
