Library Package | Classes |
---|---|
javafx.scene | Node, Scene, Stage, Pane |
javafx.scene.control | Button, Label, TextField, Slider |
javafx.scene.layout | VBox, HBox, BorderPane |
javafx.animation | AnimationTimer, Transition |
javafx.event | EventHandler, ActionEvent |
Binding Data to JavaFX Controls
Binding data to JavaFX controls enables automatic synchronization between the control's state and an observable variable. This approach simplifies data management and ensures that the UI reflects the underlying model's changes in real-time.
Unidirectional Binding
Unidirectional binding allows data to flow from an observable variable to a control, updating the control's state when the variable changes. For example:
```java
TextField textField = new TextField();
SimpleStringProperty textProperty = new SimpleStringProperty();
textField.textProperty().bind(textProperty);
```
When `textProperty` changes, the `TextField` will automatically update its text to match the new value.
Bidirectional Binding
Bidirectional binding establishes a two-way connection between a control and an observable variable, allowing both to influence each other. For example:
```java
Slider slider = new Slider();
DoubleProperty valueProperty = new SimpleDoubleProperty();
slider.valueProperty().bindBidirectional(valueProperty);
```
Changes to either the `Slider`'s position or the `DoubleProperty` will be reflected in both components.
Bind by Property Value
Instead of directly binding to the property itself, it's possible to bind a control to a specific value emitted by the observable variable. For example:
```java
Button button = new Button();
ObservableBooleanValue enabledProperty = new SimpleBooleanProperty();
button.disableProperty().bind(enabledProperty.not());
```
When `enabledProperty` is true, the button will be enabled. Otherwise, it will be disabled.
Custom Bindings
JavaFX provides a powerful API for creating custom bindings using the `Binding.Bindings` class. This allows developers to establish complex relationships between controls and observable variables.
Table of Binding Types
| Binding Type | Description |
|---|---|
| Unidirectional | Data flows from variable to control |
| Bidirectional | Data flows both ways between variable and control |
| Property Value | Control bound to a specific value from variable |
| Custom | Custom bindings created using the `Binding.Bindings` class |
Handling Events in JavaFX Applications
Mouse Events
JavaFX supports a wide range of mouse events, including click, hover, and drag. To handle these events, you can use the following methods:
- setOnMouseClicked()
- setOnMouseMoved()
- setOnMouseDragged()
Keyboard Events
JavaFX also supports keyboard events, such as key press, release, and type. To handle these events, you can use the following methods:
- setOnKeyPressed()
- setOnKeyReleased()
- setOnKeyTyped()
Touch Events
If you're developing an application for a touchscreen device, JavaFX allows you to handle touch events. These events include touch down, move, and release. To handle them, you can use the following methods:
- setOnTouchPressed()
- setOnTouchMoved()
- setOnTouchReleased()
Event Handling Architecture
JavaFX uses an event-driven architecture, where the event handling logic is encapsulated in event handlers. These event handlers are typically implemented as anonymous inner classes or lambda expressions that define the code to be executed when a specific event occurs.
Event Propagation
Events in JavaFX follow a propagation model, where they are first dispatched to the source node and then to its parent nodes,直至到达根节点。此传播顺序允许您在不同层级处理事件,例如在子节点处理具体事件,但在父节点处理更通用的事件。
Event Consuming
In JavaFX, events can be consumed, which prevents them from being propagated further up the event propagation chain. This feature allows you to control the scope of event handling and prevent unnecessary event handling code from being executed.
Method | Description |
---|---|
Event.consume() | Consumes the event and prevents further propagation. |
Event.isConsumed() | Checks if the event has been consumed. |
