问题 (James_D has showed me the solution. I'll just elaborate on how it helped me and what I did at the end of this question. Hopefully others find it useful.)

I tried to set anchor pane layout for both the HBox, but that is not working. <?xml version="1.0" encoding="UTF-8"?> <?import javafx.scene.control

问题 I'm trying to develop a file copy application. I've created a checkbox tree item with current directories on file system. But when I select first node (c:/ directory), it takes a long time. How can I select all directories easily and quickly? Here is my first FXML load class: @Override public void initialize(URL location, ResourceBundle resources) { TreeView pathTree = new MyFileTreeView().getMyFilePathTree(); vBoxFileTree.getChildren().add(pathTree); } This is my treeView component: public

问题 I have a JavaFx application with following files: MainApp.java - Java class responsible for handling the application Controller.java - Corresponding controller file Design.fxml - FXML file for the application which is loaded via MainApp.java and controlled by Controller.java Now, let's say I have another class file as Compute.java which has a method (say doSomething()). When this method terminates, I wish to open a built-in Alert box or a custom FXML file on top of the original FXML file (say
