You can get the values by calling GridPane.getColumnIndex(node) and GridPane.getRowIndex(node). You haven’t shown what you’re putting in the grid pane, and even whether you are populating it in FXML or in Java, but here’s some basic functionality. Here I (tediously) populate the GridPane in FXML, it might be better to populate it in Java (i.e. … Read more
Removing the JavaFX Frame Rate Cap You can remove the 60fps JavaFX frame rate cap by setting a system property, e.g., java -Djavafx.animation.fullspeed=true MyApp Which is an undocumented and unsupported setting. Removing the JavaFX frame rate cap may make your application considerably less efficient in terms of resource usage (e.g. a JavaFX application without a … Read more
Don’t use setGridLinesVisible(true): the documentation explicitly states this is for debug only. Instead, place a pane in all the grid cells (even the empty ones), and style the pane so you see the borders. (This gives you the opportunity to control the borders very carefully, so you can avoid double borders, etc.) Then add the … Read more
An ObservableList will fire change events when items are added and removed from the list, whether or not it is created with an extractor. However, if items in the list either are, or contain references to, observable properties, the list will fire updates when those properties change only if it is constructed with an extractor … Read more
There are numerous ways to achieve that, the most convenient would be to use JavaFX’s DataBinding mechanism: // assuming you have defined a StringProperty called “valueProperty” Label myLabel = new Label(“Start”); myLabel.textProperty().bind(valueProperty); This way, every time your valueProperty gets changed by calling it’s set method, the label’s text is updated.
Suppose this is our JavaFX class: import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.stage.Stage; public class OKButton extends Application { @Override public void start(Stage stage) { Button btn = new Button(“OK”); Scene scene = new Scene(btn, 200, 250); stage.setTitle(“OK”); stage.setScene(scene); stage.show(); } } Then we may launch it from another class like this: import javafx.application.Application; … Read more
Add a pane with no content which always grows to fit available space between the left aligned tools in the bar and right aligned ones. <?xml version=”1.0″ encoding=”UTF-8″?> <?import javafx.scene.control.*?> <?import javafx.scene.layout.*?> <ToolBar prefHeight=”40.0″ prefWidth=”318.0″ xmlns:fx=”http://javafx.com/fxml/1″ xmlns=”http://javafx.com/javafx/8″> <Button text=”Apples” /> <Button text=”Oranges” /> <Pane HBox.hgrow=”ALWAYS” /> <Button text=”Help” /> </ToolBar>
You are confusing what is not allowed with what throws exceptions. Just because something doesn’t throw an exception doesn’t mean it is allowed, or that it is safe, or that it is guaranteed to work. All changes to nodes that are part of a live scene graph must happen on the JavaFX Application Thread. JavaFX … Read more
The “quick and dirty” way is to give the Stage1Controller a reference to the Stage2Controller: public class Stage1Controller { private final Stage2Controller stage2Controller ; public void setStage2Controller(Stage2Controller stage2Controller) { this.stage2Controller = stage2Controller ; } // … @FXML private void handleTranslate (ActionEvent event){ translateFirstStage(); stage2Controller.setLabel(…); } // other code as before … } Now in your … Read more
With JFXtras there is a Window control, where you can add content and handle the internal window behavior. First you will need to put in your classpath the jfxtras library. They have some instructions where you can get the library. If you are using maven, just need to add: <dependency> <groupId>org.jfxtras</groupId> <artifactId>jfxtras-labs</artifactId> <version>2.2-r5</version> </dependency> Or … Read more
