There are many different variations of this pattern. In particular, “MVC” in the context of a web application is interpreted somewhat differently to “MVC” in the context of a thick client (e.g. desktop) application (because a web application has to sit atop the request-response cycle). This is just one approach to implementing MVC in the … Read more
Add a listener to the TextField’s textProperty: TextField textField = new TextField(); textField.textProperty().addListener((observable, oldValue, newValue) -> { System.out.println(“textfield changed from ” + oldValue + ” to ” + newValue); });
To remove the focus ring display from any control from within code: control.setStyle(“-fx-focus-color: transparent;”); To remove the focus ring for all controls, apply a stylesheet: .root { -fx-focus-color: transparent; } To only remove the ring for all buttons, use: .button { -fx-focus-color: transparent; } I find the -fx-focus-color attribute setting more straight-forward than relying on … Read more
Try ScrollPane scrollPane = new ScrollPane(); scrollPane.setFitToHeight(true); scrollPane.setFitToWidth(true); without overriding the resize() method.
Update March 2021 The previous information in this answer is now obsolete for later versions of Java and JavaFX (e.g. Java 11+). This update provides info for more recent versions. JavaFX is now available from openjfx.io or the public Maven repository as an SDK or a library set, or a module set. JavaFX has been … Read more
Yes, using an ImageView. Just call ImageView imageView = new ImageView(“…”); imageView.setFitHeight(100); imageView.setFitWidth(100); By default, it will not preserve the width:height ratio: you can make it do so with imageView.setPreserveRatio(true); Alternately you can resize the Image directly on loading: Image image = new Image(“my/res/flower.png”, 100, 100, false, false); Resizing the image on loading is useful … Read more
If you have a look at the life-cycle of the Application class: The JavaFX runtime does the following, in order, whenever an application is launched: Constructs an instance of the specified Application class Calls the init() method Calls the start(javafx.stage.Stage) method Waits for the application to finish, which happens when either of the following occur: … Read more
I thought it might be helpful to see an example which specifies the ChangeListener as an anonymous inner class like scottb mentioned. TextField yourTextField = new TextField(); yourTextField.focusedProperty().addListener(new ChangeListener<Boolean>() { @Override public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldPropertyValue, Boolean newPropertyValue) { if (newPropertyValue) { System.out.println(“Textfield on focus”); } else { System.out.println(“Textfield out focus”); } … Read more
You are correct in that the TableView control does not have a String setter method that directly manipulates the text shown when the table is empty. What you will want to do instead is use the TableView’s placeholder property which can be set to any object of type Node. For example… myTableView.setPlaceholder(new Label(“My table is … Read more
Of course. Only related property has opposite semantic and is called disabled. Which means you can use setDisable (not setDisabled) and isDisabled. Since it is a JavaFX property you can also attach listeners to disabledProperty. Check out the JavaFX documentation at http://docs.oracle.com/javafx/2/api/javafx/scene/Node.html#setDisable(boolean) Code button.setDisable(false)
