问题 I found a way to open a link on default browser using HostServices. getHostServices().showDocument("http://www.google.com"); Is there any way to open a media in default media player? Is there any way to launch a specific File or Application ? 回答1: If you want to either open a URL which has an http: scheme in the browser, or open a file using the default application for that file type, the HostServices.showDocument(...) method you referenced provides a "pure JavaFX" way to do this.

问题 At the moment, I'm making a lw interpreter for a programming language. http://www.muppetlabs.com/~breadbox/bf/ Anyways, I'm trying to implement a text area, but I want the scroll bars to be hidden. I've looked at multiple tutorials to do this, but none of them seemed to work.

问题 I have a JavaFX 8 application and want to allow a Task to modify two different UI elements. As I understand it, if I had a single Label to modify, I could bind to the Label with mylabel.textProperty().bind(mytask.messageProperty()) and use updateMessage() in the Task. How can I do this with two different arbitrary types? I've looked at the examples in the concurrency and JavaFX docs but to me they do not explain this well. I understand a Task inherently has Message(String), Progress(double

问题 I'm trying to resize the caret in a TextField without modifying the font size, but I can not do it. Does anyone know how to do that? Thanks! 回答1: I have no idea why you would want to do this. And this probably won't give you exactly what you want, but it does change the size of the caret. Note that the big caret will still be clipped to be within the bounds of the containing TextField. The small line between the m and the a is the small caret. Image transfer into stackoverflow reduced clarity

问题 I am converting an app written using Swing to JavaFX. I need an array of TextField s that I can manipulate collectively and as individual array members addressed by the array index. The following code works in Swing but I cannot find the equivalent in JavaFX, using TextField instead of JTextField . How can I achieve this in JavaFX? private ArrayList<JTextField> fieldList= new ArrayList<JTextField>(); fieldList.add(fldCompletion); fieldList.add(fldHrsToDate); fieldList.add(fldHrsToComplete);

问题 I want to create a dynamic tableview that gets its data from a json provided by a webpage. The thing is that whenever the data from the json is out of range (for example the range should be 0.8 - 0.9, but it reads 1.1), the table automatically updates the observablelist with a "RED SQUARE" image. If the data is within range, it shows a "BLUE SQUARE" image. It's like a status indicator so that the user knows if the data is correct or not. I have this code: public ObservableList<PumpSites> list
