问题 [preamble: apologies, there is a lot of code here, and some of it may not be relevant to this question while some code which is necessary to understand the problem may be missing; please comment, and I will edit the question accordingly.] Environment: Ubuntu 14.10 x86_64; Oracle JDK 1.8u25. Unit testing library is TestNG, version 6.8.13; Mockito is version 1.10.17. In my GUI application, what JavaFX calls a "controller" is pretty passive, in the sense that the only thing that this "controller

问题 Currently I'm working on Jax Rs application and I want to output Base64 encoded image to the client. The client is a mobile device. The mobile device will call this service with some parameters and the server has to draw a bar chart and send it back to the device as a base64 encoded image string. Since java Fx having the required chart libraries, I did a sample using following tutorial. "snapshot" function also worked correctly as expected (to create a image of the screen). http://docs.oracle

I am trying to create a chat application using JavaFx framework. at the photo it should look like that.This is not duplicate because the other thread is vague for a beginner like me. ListView with imageview inside I tried something like this. I'm totally noob to this thanks in advance! import javafx.application.Application; import

问题 What is the difference between a "normal" Java desktop application (with AWT or Swing), and a Java application built with JavaFX? What are the advantages and disadvantages of each? 回答1: I think what you are asking is what are the pros and cons of building a JavaFX desktop application vs a Java Swing desktop application. After experimenting with both I can point out a few differences: Java Swing Pros: Better visual designer and IDE support More full featured set of controls Good for building

问题 In JavaFx I can attach a listener to the load worker for a webEngine like this: webEngine.getLoadWorker().stateProperty().addListener( new ChangeListener<Worker.State>() { public void changed(ObservableValue ov, Worker.State oldState, Worker.State newState) { System.out.println("webEngine result "+ newState.toString()); } }); However if I try to load a document at an https address such as: https://SomeLocalMachine.com:9443/jts/admin#action=com.ibm.team.repository.manageUsers all I get printed

问题 TL;DR I'm looking for a way to have one thread raise an event in another EDIT: I say the word "immediate", which is, as some commenters have pointed out, impossible. What I mean is that it should happen reasonably quickly, in the low milli to nanosecond range if the gui thread is idle (which , if I do my job right, it should be). The case example: I have a project which has a Parent class. That Parent class creates a child thread 'Gui', which houses a javafx application and implements

问题 The JavaFX Application Thread. Sources I can find says all updates on nodes must happen in this thread. I am trying to find the documentation for this and if there are any exceptions to this rule. https://docs.oracle.com/javase/8/javafx/interoperability-tutorial/concurrency.htm As it says: The JavaFX scene graph, which represents the graphical user interface of a JavaFX application, is not thread-safe and can only be accessed and modified from the UI thread also known as the JavaFX
