javafx-8

I'm having problem. I used SceneBuilder and JavaFX. When I used layer in SceneBuilder and I tried to load it in java. I've got the error message below: javafx.fxml.LoadException: /C:/Projects/des_project2/target/classes/view/user/UserMainView.fxml at javafx.fxml.FXMLLoader.constructLoadException(FXMLLoader.java:2601) at javafx.fxml.FXMLLoader.importClass(FXMLLoader.java:2848) at javafx.fxml.FXMLLoader.processImport(FXMLLoader.java:2692) at javafx.fxml.FXMLLoader.processProcessingInstruction(FXMLLoader.java:2661) at javafx.fxml.FXMLLoader.loadImpl(FXMLLoader.java:2517) at javafx.fxml.FXMLLoader

I have an issue with my TableView and its items. I have created a small Dialog window to display warnings about my app, and inside the Dialog I have a TableView which displays the name of the warning and some information about it upon clicking on a button. I have created a WarningUtil class ( Singleton pattern) just to open / close the Dialog . The relevant code follows. The constructor of the WarningUtil class (called once only) : private WarningUtil(RootCtrl rootCtrl) { this.rootCtrl = rootCtrl; warnings = new HashMap<>(); setupWarningCallbacks(); // not relevant setupTable(); setupColumns()

i downloaded a java fxml app from https://github.com/HassanAlthaf/AlarmApplication and when i try to run it a get a "cannot find symbol" error from the MainView.java class. Here is the code from the Mainview.java file import java.net.URL; import java.util.ResourceBundle; import javafx.event.ActionEvent; import javafx.fxml.FXML; import javafx.fxml.Initializable; import javafx.scene.control.Alert; import javafx.scene.control.Alert.AlertType; import javafx.scene.control.TextField; public class MainView implements Initializable { @FXML private TextField hoursField; @FXML private TextField

I have tried a lot but not able to populate all values in the data base into my combo box table cell. Controller.java public class controller { GetConnection gc = new GetConnection(); PreparedStatement pst; ResultSet rs; Statement st; private ObservableList<Users> datas = FXCollections.observableArrayList(); public controller() { } @FXML private TableView<Users> table; @FXML private TableColumn<Users, String> c1; @FXML private void editable() { List<String> names = new ArrayList<String>(); try { ObservableList<Users> datas = FXCollections.observableArrayList(); String sql = "select * from

Basically the question title says it all. I have a column of strings (called type ) in a tableview and a corresponding column of numbers (called size ), each row representing an object CargoItem , which has the two properties type and size . Both columns are editable. The TableView is associated with the corresponding observable list of CargoItem , called cargoList . A ChoiceBox is initially set to the observable list. I have a listener attached to the ChoiceBox, so it can update a TextField with the corresponding size attribute. This works OK: if you type a new value into a cell in the size

I am using cell factory for listview with checkboxes like: listView.setCellFactory(CheckBoxListCell.forListView(new Callback < Bean, ObservableValue < Boolean >> () { @Override public ObservableValue < Boolean > call(Bean item) { BooleanProperty observable = new SimpleBooleanProperty(); observable.addListener((obs, wasSelected, isNowSelected) -> { if (isNowSelected) { if (!beanChoices.contains(item.toString())) { beanChoices.add(item.toString()); observable.setValue(true); //listView.scrollTo(listView.getItems().size() - 1); } } else if (wasSelected) { if (beanChoices.contains(item.toString())

UPDATE : This qustion moved to TableColumn should only show one specific value of a complex data type because it's more specific I want to populate a table with a complex data type Person containing name , id and a List<Person> . At the moment I get a table with the correct name , id and a third column with the whole information of other Person s but it should only show the name of the Persons s. Is there any way that my third column shows only the Person.getName() values? Keywords, solutions welcome! Thank you very much! Edit: Code Person.class public class Person { String id; String name;

Using JavaFX 8.0 and JRE 1.8.0 u45 in IntelliJ, I created a basic pixel editor app. I have two windows(stages). One is a 32x128 matrix of Circle Objects placed in a Grid Pane and the other, a Tools widow; I have one Controller.java . Using the mouse, the Tools window provides tools to draw lines, rectangles, etc. and a menu for Setup, Files and Playlists. The Files menu presents the user with Open, SaveAs and Delete. To view a saved pixel art file, the user clicks Open and via the JFileChooser , the selected file is opened and each Circle’s assigned color is displayed using the following
