I think it's possible, but I'm not sure if it's a great idea to have that be a thing. Obviously, a user should not work with an app that crashes, and if it does, it's for a good reason. It would perhaps be better to have your app send an error report back

@g4sarma Here's some code w. a file-based approach. Sorry it's not TornadoFX. That might make a good blog post, but I don't have time to mess with the Kotlin JARs so I kept it as plain Java.

First the Executive which launches itself and the UI. As it initializes, it creates a repeating task to check for a file that I created beforehand /tmp/status.txt with a "0" as the first line.

@carlw uploaded a file: Executive

Here's the notional UI. It also has a repeated task that does the writing.

@carlw uploaded a file: UI Reporting Status to a File

There are a few things I skipped over like creating the file initially. Also, you may want to slip an "EXIT" in place of the counter value as a cue to the Executive that it should kill itself as the UI is going down expectedly.

Thanks, i had another question, i am having an issue with finding a cross platform directory path finder to create files. I gave this a try but without much luck. https://github.com/harawata/appdirs The System.getProperty("user.home") also doesn't seem to work

I use Commons IO https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/FilenameUtils.html

Thanks i will give that a try 🙂

@carlw Are you sure that this works with a native build file, i mean would be able to find the path of the system the app gets installed in

?

i'm just giving you a strategy. you'd never use a hardcoded path like this in a real program.

are you using native javafx packaging?

yes

I tried building the app with tornadoFx packaging but the build artifacts just didn't work

working with OS processes in Java has always been weak (try getting a PID!)

and it's also platform-dependent

Indeed

When i try using the build artifacts to generate a dmg Error:Java FX Packager: BUILD FAILED /Users/mcgaps/Library/Caches/IdeaIC2017.2/compile-server/<app_name>/_temp_/build.xml29 Error: Bundler "DMG Installer" (dmg) failed to produce a bundle.

you're on a mac?

yes

i've only built stuff for the mac using XCode. do you have a valid developer account from apple?

No 😞

But would that help ?

I mean i guess it would fix this Did not find a key matching 'Developer ID Application: '

But there is more to this than just the Developer Id

SankeyPlot and intitial commit has been put into TornadoFX-Charts.

is there an easy way to select a tab programmatically?
