JavaFX 15 亮点

A couple of weeks ago, JavaFX version 15 was released. We’ve tailored down some of the most exciting parts of the release in this document.

Exciting features:

• JavaFX now has 3D support for the newer Intel graphics drivers on Linux
• Support for e-paper displays on i.MX6 devices was added
• FX scripting support was enhanced

Improvements:

• Better native keyboard handling and integration on iOS and Android
• Adjusted font size in JavaFX apps with enabled Monocle on Raspberry Pi
• Capped the refresh rate on iOS (to a maximum of 30 Hz)

Removal and Clean up:

• The JavaBeanXxxPropertyBuilders constructors were removed
• The deprecated finalize() methods from JavaFX property objects were removed
• Some unnecessary logging, e.g. for pinch gestures on iOS, is now skipped

In the bug fix department, you’ll find, among others:

• A fix for the SVG patterns that were drawn incorrectly
• A solution for some inconsistencies with controls, such as:
  • The incorrect arrow key traversal through tabs after reordering the tabs in a TabPane
  • The lost formatting when using Ctrl-A in HTMLEditor
  • The wrong Scrollbar position on touch supported devices
• A fix for memory leaks, e.g. in the ProgressIndicator class, in the ToggleButton.setToggleGroup() method, and in some other places
• Better code hygiene to avoid exceptions such as:
  • An IndexOutOfBoundsException when requesting focus on an empty bar
  • A StringOutOfBoundsException when adding a ChangeListener to TextField.selectedTextProperty()
  • Possible NullPointerExceptions in TabPaneSkin.performDrag(), in the MenuButtonSkinBase change listener, and while entering empty submenu with “arrow right”

Finally, these are some dependency upgrades in JavaFX 15:

• Upgraded libFFI to version 3.3
• Upgraded SQLite to version 3.32.3
• Upgraded WebKit to version 609.1
• Upgraded libxml2 to version 2.9.10
