问题 I want to have a context menu on a TreeView item. I am expecting that the ActionEvent of the event handler gives me information about which TreeView item is clicked, but I just find that getSource and getTarget return a Menu Item. How can I find out which TreeView Item has been clicked? I can have multiple treevIews in separate Tabs. FileContextMenu cm = new FileContextMenu(new EventHandler<ActionEvent>() { public void handle(ActionEvent e) { System.out.println("Open File"); //MenuItem mi =

问题 I have a JavaFX form with two combo boxes populated with Times in 15 min increments for Start and End times. I am trying to get the End time combo box to dynamically repopulate with options when the user selects a start time so that it is not possible for the user to select an End time before the start time while preserving the user's selection if the user has already selected an end time that is still after the start time. I have been able to get both boxes to populate correctly and

问题 Ok so from my stand point my code is pretty decent enough to get a passing grade but I am having trouble adding a simple refresh/shuffle button. NOT USING the aids of JOptionPane. Eclipse doesnt seem to recognize that I have created the button which doesnt make sense at all for me because its telling me something about a Node which the Button is in fact a node and it is created. But when I go into another class and add another button with the 3 line example it simply works. But when I move it

问题 I'm working on a project where the TableView looks like this: The datas are inside are a MySQL database, and I use a modell and an observableArrayList to get them. I want to make an initialize method which read the whole selected Line and save it into the TextFields (like Name-Name, Address - Address etc). I tried with this, and now I can Select the Whole Line data, but can't split it into Strings to set the TextField texts: ListViewerModell details = (ListViewerModell) table

问题 i'm trying to upload an image to mysql database using phpmyadmin and despite the program works and stores the rest of the data the image is not stored correctly. If I upload an image directly in phpmyadmin the image's size in type Blob it's 26.6 KB but if I try to uploading using javafx the image's size it's about 10 B so I think i'm not uploading correctly. @Override public void guardarMonstruo(MonstruoDTO monstruo) { con= ConexionBDA.getInstance().getCon(); try { if (con != null){ byte[]

问题 I'm trying to develop a cross-platform application that works on Desktop and Android as well using JavaFX and Gluon. At runtime my code creates a serialized file in my resource folder. I also need to read and write serialized data from/to it. I managed to work it on desktop, but not on android. Because it have a different file structure I guess. That is why I try to get the file path dynamically. Existing resource files, which are created before runtime (and not modified) seems to works fine

问题 Since JavaFX has become OpenJFX and needs to be added as a dependency to your Maven project, debugging a OpenJFX application has become complicated. In this question it is already answered how to solve it for NetBeans. But IntelliJ works slightly different. The Ppom.xml has been setup according to this example. How can you run an OpenJFX (JavaFX) application which is configured as a Maven project in debug mode in IntelliJ? 回答1: If you would copy the addition of VM options in the pom.xml for
