5 JavaFX and JDK for ARM Kevin Rushforth StartingwithJDK8u33,JavaFXhasbeenremovedfrombothOracleJDKforARMandOracleJavaSEEmbedded. This is a resource trade off within Oracle. Included in that difficult trade off decision was the ongoing investment needed to properly support FX in a world where so much the hardware is not standardized -- it really is difficult to have enough hardware and testing resources committed to support FX on ARM. It is important to understand that when we say support, we are not talking about just "running" on a device like the Raspberry PI -- but providing support for paying customers that are almost certainly going to be using hardware that is customized for their embedded product. ThisdoesnotmeanthatFXisgoingawayonotherplatforms,andhopefullydoesnotmeanwewillbedisappearingfromARMcompletely. The core JavaFX team will continue working on the ARM port as resources permit, hopefully with involvement of members of the OpenJFX community. We have continued to demonstrate this commitment with the moving all of the JavaFX sources to OpenJFX, and maintaining an up to date OpenJFX Wiki which includes detailed articles on building for ARM. WewillcontinuetodowhatwecantomakeiteasiertobuildandoverlayOpenJFXontopoftheARMJDKs. WehopetoarrangeforaexternalbuildofOpenJFXforARMsothatmorepeoplewillbeabletoeasilyobtainacurrentbuild. Most of the FX source code is shared across all ports, and we will continue to do regular internal builds of linux-armv6hf to ensure that it runs.wewillcontinuetomaintainthe*monocleglassplatforminanycase,asweuseitforsomeofourdesktopunittests. We have received a lot of help from the community -- particularly for ios and Android. Now we hope we can work together to keep Linux ARM viable and interesting. 5 Copyright 2015 Oracle and/or its affiliates.

13 Displaying HTML in JavaFX public class WebViewDemo extends Application { public static void main(string[] args) { launch(args); public void start(stage stage) { WebView webview = new WebView(); webview.getengine().load(" Scene scene = new Scene(webView); stage.setscene(scene); stage.settitle("web View Demo"); stage.show(); } } 13 Copyright 2015 Oracle and/or its affiliates.

14 JavaFX mit JFXPanel Komponente in Swing Anwendungen einbinden public class Test { Class JFXPanel java.lang.object Scene scene = createscene(); java.awt.component fxpanel.setscene(scene); java.awt.container } javax.swing.jcomponent javafx.embed.swing.jfxpanel private static void initandshowgui() { // This method is invoked on Swing thread JFrame frame = new JFrame("FX"); final JFXPanel fxpanel = new JFXPanel(); frame.add(fxpanel); frame.setvisible(true); Platform.runLater(new Runnable() { private static void initfx(jfxpanel fxpanel) { // This method is invoked on JavaFX thread public static void main(string[] args) { SwingUtilities.invokeLater(new Runnable() public void run() { initfx(fxpanel); public void run() { initandshowgui(); } }); }); } } } 14 Copyright 2015 Oracle and/or its affiliates.

15 [SwingNode, JFXPanel] Focus issue when mixing JavaFX and Swing multiple times - Runtime RT public class EmbeddedTestWithFX extends JFrame { Details: Bug in JDK 8u20 and JDK8u40EA on Windows 8 If Swing is embed into JavaFX which is embedded into Swing, the focus of controls have issues TextArea is shown, but It doesn't get the focus by clicking on it (It's the same for other controls, like jbuttons). If a FocusListener on the JTextArea is registered, you see that it becomes the focus after a click, but it loses the focus instantly. The example starts to work with: -Djavafx.embed.singleThread=true public EmbeddedTestWithFX() { setsize(new Dimension(300, 300)); JTextArea textarea = new JTextArea(); textarea.setsize(new Dimension(150, 150)); JPanel container = new JPanel(); container.setlayout(null); container.add(textarea); JFXPanel jfxpanel = new JFXPanel(); Platform.runLater(() -> { SwingNode swing = new SwingNode(); StackPane stack = new StackPane(swing); Scene scene = new Scene(stack); swing.setcontent(container); SwingUtilities.invokeLater(() -> jfxpanel.setscene(scene)); }); Clicked the TextArea, it holds the focus and text could be entered. } setcontentpane(jfxpanel); 15 Copyright 2015 Oracle and/or its affiliates. All rights reserved. } public static void main(string[] args) { new EmbeddedTestWithFX().setVisible(true); }
