# JavaFX
`A repo including all the core concepts of JavaFX`
## What is JavaFX?
JavaFX is a GUI(Graphical User Interface) Library in Java similar to core GUI Library Swing.
## Topics Covered
- **Scene**
- **Scene Builder**
- **Switching Scenes** within a Stage
- typecasting to switch scenes
```java
stage = (Stage) ((Node) event.getSource()).getScene().getWindow();
```
- Using CSS Styling with Scenes
- adding css stylesheet to the Scene
```java
Scene.getStylesheets().add(getClass().getResource("Main.css").toExternalForm());
```
- reusing stylesheet to use in different scenes
```java
String css = this.getClass().getResource("Main.css").toExternalForm();
Scene.getStylesheets().add(css);
```
- Communicating b/w different controllers
- Using FXML elements within controllers
```java
@FXML
TextField username;
private Stage stage;
private Scene Scene;
private Parent root;
```
- Reusing FXMLLoader Instance
```java
FXMLLoader loader = new FXMLLoader(Objects.requireNonNull(getClass().getResource("Scene2.fxml")));
root = loader.load();
```
- Creating Instances of Other Controllers of the package
```java
Scene2_Controller scene2_controller = loader.getController();
```
- **ImageView** Node
- How to set up ImageView Node in SceneBuilder
- Switch Images of the ImageView Node
```java
public void toggleImage() {
if (imageContainer.getImage() == image1) {
imageContainer.setImage(image2);
} else {
imageContainer.setImage(image1);
}
}
```
- **TextField** Node
- **CheckBoxes**
- **RadioButtons**
- Make sure to put all the radio-buttons in the same toggle group variable in the fxml file
```fxml
```
- **Color Picker**
- How to set the background of the AnchorPane(`javafx.Scene.layout.AnchorPane`) with Color(`javafx.Scene.paint.Color`)
```java
AnchorPane background;
Color color = Color.RED;
background.setBackground(new Background(new BackgroundFill(color, CornerRadii.EMPTY, Insets.EMPTY)));
// or
background.setBackground(new Background(new BackgroundFill(color, null, null)));
```
- **Choice Boxes**
- How to set the items of a choicebox and set the action event method
- To add anything to the nodes after the root node has been declared with the FXML File we can use the intialize method as
```java
public class Controller implements Initializable {
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
// do something
}
}
```
- Adding items to the choicebox
```java
private String[] food = {
"sushi",
"burger",
"ramen"
};
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
choiceBox.getItems().addAll(food); // addAll takes a collection
}
```
- setting the onAction event of choicebox or any node
```java
@FXML
private ChoiceBox choiceBox;
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
choiceBox.setOnAction(this::showFood); // this:: is a method reference operator
}
```
- **Slider**
- adding the ChangeListner to the slider using initialize method in the Controller class
```java
class Controller implements Initializable {
@Override
public void initialize(URL arg0, ResourceBundle arg1) {
temperatureSlider.valueProperty().addListener(new ChangeListener() { // Using Number Generic Type since temperature variable is an integer
@Override
public void changed(ObservableValue extends Number> observableValue, Number number, Number t1) {
temperature = (int) temperatureSlider.getValue();
temp.setText(Integer.toString(temperature)+ "C");
}
});
}
}
```
- **Spinner**
- adding values to the Spinner with _SpinnerValueFactory_
```java
SpinnerValueFactory valueFactory = new SpinnerValueFactory.IntegerSpinnerValueFactory(1, 10);
// default value
valueFactory.setValue(1);
foodSpinner.setValueFactory(valueFactory);
currentValue = foodSpinner.getValue();
spinnerLabel.setText(Integer.toString(currentValue));
```
- adding eventListner on value change
```java
foodSpinner.valueProperty().addListener(new ChangeListener() {
@Override
public void changed(ObservableValue extends Integer> observableValue, Integer integer, Integer t1) {
currentValue = foodSpinner.getValue();
spinnerLabel.setText(Integer.toString(currentValue));
}
```
