问题 I have just started working with JavaFX and have come to an obstacle. When I open SceneBuilder it renders very strangely. When the window is restored it seems zoomed in, and when maximized it looks better, but still not quite OK and inoperable. The same goes for HelloWorld example that I created, and examples I found on internet, so I think it is something systemic. I have tried with Java 7u71 and with Java 8u25. No change. Please help if you know how to fix this. 回答1: After reading system

问题 So, it's a little confusing but here is the thing: I created a window with SceneBuilder, and created the controller and everything, there is a button in the window. The button setOnAction() method makes the program open another window, the thing is, this other window is another class and I want to pass information to this other window, but it seems I cannot. Here's some code example: MainWindow: confirm.setOnAction(event->{ try { LibraryWindowController lwc = new LibraryWindowController();

问题 I'm working on a project that needs a slide out menu, preferably on hover it slides out, how would I go about doing this? I want to program the slide out menu in a FXML file. Is there anyway to do this? What would I use(Split Pane, Separators)? Thanks! 回答1: Use a TranslateTransition to move the menu. Use a Pane to place the menu above the normal content. The following example doesn't use fxml for simplicity, but of course you can create the nodes from fxml too: @Override public void start

问题 I'm trying to develop a Gradle project which involves JavaFX. Specs: Linux Mint 18.3, Java 11, Eclipse 2019-06, JavaFX: either 13 or 11... A couple of useful answers to questions have helped me over the past hours: this one tells me (with useful clonable example) how to configure things, at least using a Java file to hold my project's main class (in fact I ultimately want to write all my code in Groovy ideally), in order to overcome the error "JavaFX runtime components are missing, and are

问题 So basically I'm developing this Javafx app following the DAO pattern... and I want the floats to have that .00 end instead of .0 (to represents the balance.. money ) balance records in tableview with .0 here's how I initialized the tableview components idC.setCellValueFactory(cellData -> cellData.getValue().idProperty().asObject()); balanceC.setCellValueFactory(cellData -> cellData.getValue().balanceProperty().asObject()); dateC.setCellValueFactory(cellData -> cellData.getValue()

问题 Trying to add children to a GridPane with row and column indices. They show up in the gui, but using GridPane.getColumnIndex(node) always returns null. GridPane grid = new GridPane(); for (int i = 0; i < 20; i++) { for (int j = 0; j < 20; j++) { grid.setGridLinesVisible(true); Button myBtn = new Button("foo"); GridPane.setColumnIndex(myButton,i); GridPane.setRowIndex(myButton,j); grid.getChildren().add(myButton); } When I try to use this algorithm I got from the answer on javafx GridPane
