问题 So of course I dive straight in to creating a simple example. public class Main extends Application { URL bla = getClass().getResource("/sample.fxml"); @Override public void start(Stage primaryStage) throws Exception{ //If you get weird errors: http://zenjava.com/javafx/maven/fix-classpath.html //but not actually my issue.

问题 I have a project in school where I have to develop a program where you first can choose whether you want to save/read to/from a SQL DB or to save/read to/from XML. I've made a GUI where you can choose between both methods. The GUI closes after the user clicks on one of the buttons and the MainMenu GUI opens. Now I need to know in the MainMenuController what the user choose. I found online a Method to call the MainMenuController inside the first controller, with FXMLLoader.getController() .

问题 So, this is my main FXML file, called 'Home.fxml': <VBox maxHeight="1.7976931348623157E308" maxWidth="1.7976931348623157E308" minHeight="-Infinity" minWidth="-Infinity" prefHeight="500.0" prefWidth="700.0" xmlns="http://javafx.com/javafx/8.0.60" xmlns:fx="http://javafx.com/fxml/1"> <fx:include source="MenuBar.fxml" /> <Label alignment="CENTER" maxWidth="1.7976931348623157E308" text="Welcome to MSMusic" textAlignment="CENTER"> <font> <Font size="62.0" /> </font> </Label> <fx:include source=

问题 I am building a TableView in Gluon Scene Builder. I want to have a different background colour for cells in each column. Can I do this just through the FXML file and CSS? With a CSS style class .column-1 I can do: .column-1 {-fx-background-color: white;} Except that also styles the column header! There doesn't seem to be a way to specify column cells only. I have seen examples where people have managed it through java code - but doesn't this defeat the point of JavaFX having this CSS/FXML

问题 I have a Java application with a view written in FXML. I am wanting to select a default tab, so when the program launches the first tab is shown as selected. I have seen the best way to do this is create an initialize() method in the controller and annotate it with @FXML which should the be loaded. For some reason though, the method is never executed. Code is below. MainApp.java import controller.Controller; import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx

问题 I have a recursive case of FXML loading needed here. If I choose to View an Objective, it takes me to another instance of the screen that loads a list of Strategy objects. If I choose to view a Strategy, it takes me to another instance of the screen that loads a list of Tactic objects. If I view a Tactic, it takes me to another instance of the screen that loads a list of Task objects. Naturally, I decided to use a base controller class, ViewChildItemController to handle inheritance. Then I
