I have a `javafx.scene.control.TreeView` and i want to add some new `javafx.scene.control.TreeItem&lt;custom data class&gt;` objects to a node when something is clicked... but i'm having trouble working out how to do this
some JavaFX answers seem to suggest `myTreeView.children.addAll` but this is private?
also tried `myTreeView.edit( new object )` but that didn't seem to do anything (need to force repopulate?)

this is more of a JavaFX question in fairness but i'm taking inspiration from <https://github.com/edvin/tornadofx-samples/blob/master/treeviews/src/main/kotlin/no/tornado/fxsample/treeviews/DemoTreeViews.kt>
