问题 I have this field in which I insert port number. I would like to convert the string automatically into number: fieldNport = new TextField(); fieldNport.setPrefSize(180, 24); fieldNport.setFont(Font.font("Tahoma", 11)); grid.add(fieldNport, 1, 1); Can you tell how I can do this? I cannot find suitable example in stack overflow. EDIT: Maybe this: fieldNport.textProperty().addListener(new ChangeListener() { @Override public void changed(ObservableValue o, Object oldVal, Object newVal) { try {

问题 So i created a javafx project, it has 3 packages, application, controller, and an images package that holds all the images im using. The program runs fine if i just compile and run, no errors. However, when i create a jar from it, by selecting the build.fxbuild, everything goes smoothly and it tells me it is successful but when i try to double click the jar file nothing opens but java starts running in the background until i force close it. Im running OSX yosemite, and im on java 1.8 if that

问题 I have a project in javafx , I have 3 dependencies I try to combine them with my principale jar using maven : The result I got a jar (1.82mb) but when I click he dosen't launch noting appears. pom.xml <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <dependencies>

问题 I am looking for a way to get the selected cell of a TableView control. Note that I don't just want the cell value, I want an actual TableCell object. One would expect that the method: tableView.getSelectionModel().getSelectedCells().get(0) does just that, but it returns a TablePosition object, which gives you row and column information, but I don't see a way to get TableCell object from that. The reason I need this is because I want to respond to a key press, but attaching an event filter to

问题 I'm working in JavaFX for a class, and I'm trying to apply a gradient to a sphere, but (obviously), I can't figure out how to do it. I'm stuck because I know that a sphere is an object, and so it needs to have a material, but (as far as colors go), a PhongMaterial only takes one color, and so it won't take a gradient because a gradient is a range of colors. So basically what I'm trying to is the following: Sphere sphere = new Sphere(50); RadialGradient rg = new RadialGradient(0, 0, 0, 0, 5,

问题 I have been experimenting with the TreeTableView in JDK 8 . After getting my program up and functioning, I noticed a problem that when I scrolled, rows would be getting blanked out. I have tried everything from resetting the visibility of the cell, when it updates, in hopes that it would redraw when it gets updated, or even resetting the visibility of the column. Here is a test applet I wrote to show that when you scroll for a tree table view, the rows get blanked out, but for a table view,

问题 I need to detect if a node is currently displaying. I.e. if my Node is in a TabPane, I need to know if it is in a selected tab or not. In the example, I want to know when the HBox is displaying.The visibleProperty and managedProperty of Node, does not seem to help me: public class VisibleTest extends Application { @Override public void start(Stage primaryStage) throws Exception { TabPane tabpane = new TabPane(); tabpane.getTabs().add(new Tab("Tab1", new Label("Label1"))); HBox hbox = new HBox

问题 Is there a way to know if a scroll bar is present on a table view? (Other than what I did in my code below) My goal is to position 2 arrow images (to close/open a side panel) on the right side of a table (over the table.). But I don't want to put them over the scroll bar. The table content is a result of a search, so sometime the scroll bar is visible and other time it is not. If there is not enough items. I want the position of my arrows to change every time the tableview items change. I

问题 For an application I am developing, I need the user to input a number of rows of data. The exact number is variable and the users should be able to add rows themselves too. I've got this all working now with a JavaFX Dialog, apart from the fact that when you add rows, the Dialog is not resized accordingly. Is there a way to get the Dialog to resize automatically when a row is added? Below is a demo application with a sample test application with a Dialog similar to what I want. package test
