I am currently working on a project using JavaFX where I have 3 ComboBoxes. One for selecting and displaying the hour, another one for the minutes and a third one for selecting AM or PM.
When a value in one of the ComboBoxes is selected, it enters a timestamp into my SQL-Database. What I am trying to do now is have a selection shown when the window opens, in the initialize method, using an index with the goal of taking my Timestamp from the selection in the database and having the ComboBoxes set with the time from the database.
I have tried:
StartCB.getSelectionModel().setSelectedIndex(1);
and
StartCB1.getSelectionModel().selectFirst();
hoping the value will show when I open the window.
Any ideas? I have copied my code from the class below.
Thank you,
Jeff

What's wrong with my code?
I have a javafx tableview with dynamic columns in the sense that the columns are added at run time. I am not using any model class and the data is populated through an observable list. After the initial load of the table, the data is okay, the problem arises when I scroll through the table, the initial values of the table are loaded back or if the table was empty, all the data i have input get cleared. Here is my code
this is my connection
public Connection conn;
TableColumn tc = null;
TableView <ObservableList> table = new TableView<>();
ObservableList items;
public Connection dbcon() {
try {
String url ="jdbc:mysql://localhost:3306/"; //koma //emerald

PreparedStatement pst = conn.prepareStatement(createdb);
pst.execute();
Statement stt = conn.createStatement();
stt.execute("use school");
} catch (Exception e) {

}
return conn;
}
then this is the start method where i load the data initially
public void start(Stage primaryStage) {

I can't seem to get it right. I have a listbox with category items. I also have a data model that defines the ID, Name, Lastname, Category.. and an ObservableList that holds the data. I'm trying to update the existing object in case the user click on the same item in the listbox and change name, lastname.
Here is my code:
public class FXMLDocController implements Initializable {
ObservableList<String> listitems = FXCollections.observableArrayList(
"Visual Basic", "ASP.net", "JavaFX");
ObservableList<Persons> personData = FXCollections.observableArrayList();
Persons pp = new Persons();
private Label label;
#FXML
private TextField txtName;
#FXML

private Button btnSave;
#FXML
private TextArea txtArea;
#FXML
private ListView<String> listview = new ListView<String>();
#FXML
private Button btnTest;
#FXML
private Label lblCategory;
#FXML
private Label lblIndex;
#Override
public void initialize(URL url, ResourceBundle rb) {
listview.setItems(listitems);
}
#FXML
private void handleSave(ActionEvent event) {
String category = lblCategory.getText();
boolean duplicate = false;
//Add data. Check first if personData is empty
if (personData.isEmpty()){
pp = new Persons(Integer.valueOf(lblIndex.getText()),category,txtName.getText(),txtLastName.getText());
personData.add(pp);
}else{
for(int i = 0 ; i<personData.size() ; i ++){
if(Integer.toString(personData.get(i).getID()).equals(lblIndex.getText())){
duplicate = true;
}else{
duplicate = false;
}
}
System.out.println(duplicate);
if (duplicate == false){
pp = new Persons(Integer.valueOf(lblIndex.getText()),category,txtName.getText(),txtLastName.getText());
personData.add(pp);
}else{
System.out.println("Duplicate");
// Do Update later.
}
}
//Show data to Test
System.out.println("-- START OF LIST --");
for (Persons person : personData){
System.out.println(person.getID() + " " + person.getCategory()+ " " + person.getName() + " " + person.getLastname() + " " );
}
System.err.println(" ");
}
#FXML
private void handleListClick(MouseEvent event) {
lblCategory.setText(listview.getSelectionModel().getSelectedItem());
lblIndex.setText(String.valueOf(listview.getSelectionModel().getSelectedIndex()));
}
}
If I click multiple times on one item on the listbox it works well.. but if for example I click on Visual Basic, then ASP.net the go back to Visual Basic it still accepts it. :(
Need advice and help. Please
Here is the code based on Phil's suggestion
#FXML
private void handleSave(ActionEvent event) {
String category = lblCategory.getText();
boolean duplicate = false;
int x = 0;
//Add data
Persons newPerson = new Persons(Integer.valueOf(lblIndex.getText()), category, txtName.getText(), txtLastName.getText());
if (!personData.contains(newPerson)) {
personData.add(newPerson);
}else{
System.out.println("Duplicate!");
}
//Show data
System.out.println("-- START OF LIST --");
for (Persons person : personData){
System.out.println(person.getID() + " " + person.getCategory()+ " " + person.getName() + " " + person.getLastname() + " " );
}
}
here's my Persons Class
public class Persons {
private SimpleIntegerProperty id;
private SimpleStringProperty name;
private SimpleStringProperty lastname;
private SimpleStringProperty category;
public Persons(){}
public Persons(int id, String category, String name, String lastname){
this.id = new SimpleIntegerProperty(id);
this.name = new SimpleStringProperty(name);
this.lastname = new SimpleStringProperty(lastname);
this.category = new SimpleStringProperty(category);
}
public Persons(String name, String lastname){
this.name = new SimpleStringProperty(name);
this.lastname = new SimpleStringProperty(lastname);
}
#Override
public boolean equals(Object o){
if (o == this) return true;
if (!(o instanceof Persons)){
return false;
}
Persons persons = (Persons) o;
return persons.id.equals(id) &&
persons.name.equals(name) &&
persons.lastname.equals(lastname) &&
persons.category.equals(category);
}
//SETTERS
public void setID(int id) {
this.id = new SimpleIntegerProperty(id);
}
public void setName(String name) {
this.name = new SimpleStringProperty(name);
}
public void setLastname(String lastname) {
this.lastname = new SimpleStringProperty(lastname);
}
public void setCategory(String category) {
this.category = new SimpleStringProperty(category);
}
//GETTERS
public int getID() {
return id.getValue();
}
public String getName() {
return name.getValue();
}
public String getLastname() {
return lastname.getValue();
}
public String getCategory(){
return category.getValue();
}
// PROPERTIES
public SimpleIntegerProperty idProperty(){
return this.id;
}
public SimpleStringProperty nameProperty(){
return this.name;
}
public SimpleStringProperty lastnameProperty(){
return this.lastname;
}
public SimpleStringProperty categoryProperty(){
return this.category;
}
}
Ok, this looks good. Just one little thing in your equals implementation:
#Override
public boolean equals(Object o) {
if (o == this) return true;
if (!(o instanceof Persons)) {
return false;
}
Persons persons = (Persons) o;
// persons.id.equals() leads to the default implementation in Object
// --> instead use this one.
// The Property classes have their own isEqualTo method
// with get(), you will get your simple boolean from the returned BooleanBinding
return persons.id.isEqualTo(id).get() &&
persons.name.isEqualTo(name).get() &&
persons.lastname.isEqualTo(lastname).get() &&
persons.category.isEqualTo(category).get();
}
The default equals implementation from Object just compares if it is the same instance. And we are creating a new instance and check with contains(...) if the list contains the Persons.
Here is the whole code I used to test it:
public class Main extends Application {
private ObservableList<String> listitems = FXCollections.observableArrayList("Visual Basic", "ASP.net", "JavaFX");
private ObservableList<Persons> personData = FXCollections.observableArrayList();
private TextField txtName = new TextField();

I'm having having trouble getting a correct output from tableview. I'm using a button to set one item from tableview to a label. However, it prints "StringProperty [Value pineapples]" where I would like it to be just "pineapples".
The tableview gives them correctly.
public class ProductListController implements Initializable {
#FXML public TableView<Model> tableview ;

ProductID.setCellValueFactory(cellData -> cellData.getValue().ProductIDProperty());
ProductName.setCellValueFactory(cellData -> cellData.getValue().ProductNameProperty());
ProductPrice.setCellValueFactory(cellData -> cellData.getValue().ProductPriceProperty());
buildData();

Model
public class Model {
public SimpleIntegerProperty ProductID = new SimpleIntegerProperty();
public SimpleStringProperty ProductName = new SimpleStringProperty ();
public SimpleIntegerProperty ProductPrice = new SimpleIntegerProperty();
private final SimpleBooleanProperty Checked = new SimpleBooleanProperty(false);
public SimpleBooleanProperty checkedProperty() {
return this.Checked;
}
public java.lang.Boolean getChecked() {
return this.checkedProperty().get();
}
public void setChecked(final java.lang.Boolean checked) {
this.checkedProperty().set(checked);
}
public SimpleIntegerProperty getProductID() {
return ProductID;
}
public SimpleStringProperty getProductName() {
return ProductName;
}
public SimpleIntegerProperty getProductPrice() {
return ProductPrice;
}
Since getProductName() returns a SimpleStringProperty, you need to retrieve the String from it using the get(). Just use :
String prd = model.getProductName().get();
Your model is implemented incorrectly. You should use the following pattern:
public class Model {
private SimpleStringProperty productName = new SimpleStringProperty();
public SimpleStringProperty productNameProperty() {
return productName ;
}
public final String getProductName() {
return productNameProperty().get();
}
public final void setProductName(String productName) {
productNameProperty().set(productName);
}
}
and similarly for the other properties.
If you use the e(fx)clipse plugin, you can generate the methods automatically from the property definition by right-clicking, choosing "Source" and then "Generate JavaFX Getters and Setters". I think NetBeans has similar functionality.
