如何在javaFX8中處理多個文本字段輸入？

Question

當單位TextField和數量TextField在焦點時，輸入值應該相應地輸入。

void requestFocus(){ 
    Platform.runLater(new Runnable() { 

     @Override 
     public void run() { 
      UnitText.requestFocus(); 
      System.out.println("Request focus thread"); 
     } 
    }); 
} 

@Override 
public void initialize(URL url, ResourceBundle rb) { 
    UnitText.requestFocus(); 
}  

Answer 1

你可以做

private TextField lastFocusedTextField ; 

@Override 
public void initialize(URL location, ResourceBundle resources) { 
    lastFocusedTextField = unitText ; 

    unitText.focusedProperty().addListener((obs, wasFocused, isNowFocused) -> { 
     if (isNowFocused) { 
      lastFocusedTextField = unitText ; 
     } 
    }); 

    quantityText.focusedProperty().addListener((obs, wasFocused, isNowFocused) -> { 
     if (isNowFocused) { 
      lastFocusedTextField = quantityText; 
     } 
    }); 



} 

在你的按鈕處理

，現在就

@FXML 
public void handleButton() { 
    // process button press in lastFocusedTextField... 
}
