javafx-8

问题 It is a bit weird or maybe there is something wrong with my code. I am setting JavaFX application ICON which is very well visible on Windows system but not on Ubuntu. On Windows: On Ubuntu: Any idea about the reason behind this. Code Sample: @Override public void start(Stage stage) throws Exception { try { setUserAgentStylesheet(STYLESHEET_MODENA); FXMLLoader loader = new FXMLLoader(); Parent root = (Parent) loader.load(getClass().getResourceAsStream("ui/ParentWindow.fxml")); final

问题 When to use translate and when relocate in order to move a node? In the end of the day it seems they do the same thing (visually); move the node; the first by doing a translation on the origin (the x, y stays the same), the second by changing the x, y coords. So suppose i want to move a node in a specific point in the screen.. should i use node.relocate(x,y) or node.setTranslateX(x), node.setTranslateY(y)? To demostrate what I mean I have made a sample program you can play with: A rectangle

问题 So I have a TextArea and as the user pastes paragraphs into it, or just writes in it, I want it to expand vertically to reveal all the available text. I.e. not to use a scrollbar in the text field itself... much like what happens on many web pages. Many users, myself included, don't like to be forced to edit in a small window. Exactly how Facebook status updates box works. I've tried myTextArea.autoSize() wrapped in an myTextArea.textProperty().addListener(new ChangeListener()....); but that

问题 JavaFX 2 does not provide validation support (masks, input filtering and so on...). It is difficult to adopt a technology that does not offer basic functionalities. I am trying to implement my own validators, but that is a big pain. Are there any news in JavaFX 8 about validation? I was trying to find new features, but I don't know where to search, it is difficult to find exactly what will be the changes in JavaFX 8. I need to know about it, because I was considering JavaFX for a new

问题 I've stumbled on an issue with Comboboxes in javafx2.2. This is the scenario: Users click on the 'editFile' button. Another pane becomes visible (with the setVisible method). This pane contains 6 comboboxes. Three of them have fixed items: cboReport, cboSales, cboSend. Three of them get their data from a db (ObservableList) and get populated when the pane becomes visible: cboFile, cboCustomer, cboVet The user selects a file number from the cboFile. The rest of the comboboxes are beeing set

问题 I'm currently reading the book Growing Object-Oriented Software Guided by Tests which gives a decent introduction into test driven development. One drawback is that the code developed through the book is based on Swing. For my next project I'd like to use Java FX 2 and I'm wondering if there are any GUI testing frameworks out there for it? The book introduces windowlicker, which allows testing Swing applications only. 回答1: There is a library named JemmyFX. Jemmy itself is a set of libraries

问题 I have a class Foo which just load the FXML and create the scene. In the FXML, I set the controller to be FooController ( fx:controller="FooController" ) And I add a MenuButton: <MenuButton fx:id="menuButton" layoutX="264.1875" layoutY="146.5" mnemonicParsing="false" text="MenuButton" /> And I try to set the menuButton in the FooController: public class FooController implements Initializable{ @FXML final MenuButton menuButton = new MenuButton("Modalities"); @Override public void initialize

问题 I have a pretty nasty bug on JavaFX (jdk 1.8.0_91) occurring in my application in which several progress bars are displayed and update (randomly or at the same time). Sometimes, especially when a progress bar is filled (it had a style class to the progress bar) but sometimes also in the middle of nothing, the software blocks and I have this trace appearing several times (not always the same number, but the last one was 27 times) : Exception in thread "JavaFX Application Thread" java.lang

问题 Edit #2 : Since it looks like a bug i already posted a bug report in the javaFx-jira. You have to have an account to have access to the issue. I will keep this post up-to-date, if there is new information. Original post: I have a simple UI with a button and a TreeView. If the button gets pressed there should be a new item added to the TreeView. This item should be editable as soon as it appears in the tree. import javafx.fxml.FXML; import javafx.scene.control.TreeItem; import javafx.scene

问题 I'm creating rich text component with selection capabilities for JavaFX project and facing some difficulties. I'm trying to catch on which TextFlow object user presses mouse button and on which another TextFlow he releases it. But after MOUSE_PRESSED event i can interact only with that TextFlow, who fired it, until i release the mouse. Here is similar example with Labels: package sample; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Label;
