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
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
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
nothing appeared in the scene Your sample mesh rendered OK for me. Perhaps you didn’t have your camera setup correctly or have your mesh scaled so that it was visible. Your sample mesh doesn’t do much, it is one triangle facing towards the camera and a second triangle facing away from the camera. And is … Read more
The simplest solution is to edit the FXML file and reorder the containers appropriately. As an example, my current application has a registration dialog in which a serial number can be entered. There are 5 text fields for this purpose. For the focus to pass from one text field to the other correctly, I had … 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>
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
Node.setVisible(boolean) just toggles the visibility state of a Node. To exclude a Node from its parents layout calculations you additionally have to set its managed state, by calling Node.setManaged(false). If you want the managed state to be updated automatically alongside the visibility, you can use a binding as @jewelsea pointed out: node.managedProperty().bind(node.visibleProperty());
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
Use a List<String> (for example) for the data type, and just set the cell value factory as a callback that indexes into the list. For example, this will create a TableView<List<String>> that is constructed out of an arbitrary tab-delimited text file. Not all rows in the file need have the same number of elements (it … Read more
