`Node` adds InvalidationListeners to its parent's `disabled` and `treeVisible` properties and calls its own `updateDisabled()` and `updateTreeVisible(boolean)` methods when the property values change.
These listeners are not required, since `Node` can easily call the `updateDisabled()` and `updateTreeVisible(boolean)` methods on its children, saving the memory cost of maintaining listeners and bindings. ------------- Commit messages: - Merge - added tests - Remove Node.disabled and Node.treeVisible listeners Changes: https://git.openjdk.org/jfx/pull/841/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=841&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8290765 Stats: 69 lines in 3 files changed: 57 ins; 10 del; 2 mod Patch: https://git.openjdk.org/jfx/pull/841.diff Fetch: git fetch https://git.openjdk.org/jfx pull/841/head:pull/841 PR: https://git.openjdk.org/jfx/pull/841
