i've used this to troubleshoot weak reference problems. Specifically, when two classes have a bi-directional relationship with one another, there's not enough information to provide the GC with a decision of which to reclaim. So, I always set one side of the bi-directional relationship to be a WeakReference. so, the GC can decide to let one reference go, and then the GC can proceed without a cycle.

this weak concept is standard programming in other languages like Objective-C. I'm not sure why it's so hidden in Java

thx, now I'm certain its the weakReference

should I attach the list to the properties or what is the best way to let it depend on the treeview?

@bkenn Cool! Did you run into any issues implementing it?

bkenn

03/03/2018, 8:35 PM

@edvin Yeah i did. I had to create some custom tasks to to create a directory structure that I can copy into the

fxlauncher.jar

@bkenn That's right, it's not exactly straight forward 🙂

The plugin should probably have better support for it

bkenn

@edvin Yeah, since the custom ui is so simple it may be beneficial to add the tasks to the fxlauncher gradle plugin.

Copy code

task("copyMeta", type: Copy) {
    dependsOn('jar')
    group = "deploy"
    from 'build/resources/main/META-INF'
    into 'build/target/classes/META-INF'
}

task("copyAll", type: Copy) {
    dependsOn "copyMeta"
    group = "deploy"

    from('build/classes/java/main')
    from('build/resources/main/') {
        include '*.css'
    }

    into 'build/target/classes'
}

That looked clean 🙂

And them in your main project implement a task like such:

Copy code

task("generateFXJar", type: Exec) {
    dependsOn('embedApplicationManifest', ':launcherui:copyAll')
    group = "fxlauncher"
    workingDir './build/fxlauncher'
    commandLine 'jar', 'uf', 'fxlauncher.jar', '-C', '../../../launcherui/build/target/classes', '.'
}

I can upload a sample to github in a little bit.

@bkenn Very nice! I'll include this functionality in the gradle plugin

Hi. When I close a modal window with close() not only the modal closes but the application exits. Is close() not the right function? With version 1.7.14 it works as expected. What can I do?
