Как вставить в таблицу имя файла, загруженного файловым устройством в javaFX?

Question

Я пытаюсь заполнить таблицу именем файла, сделанным filechooser, в столбце fileName, как я могу включить имя файла в этот столбец Tableview?

это интерфейс с sceneBuilder

Answer 1

Вобще

Table1.getItems().add(new PopulateTable(0, fileName, "")); 

т.е.

public void AddFileAudio(ActionEvent event) { 

    FileChooser fileChooser = new FileChooser(); 
    fileChooser.setTitle("Seleziona il file da caricare"); 
    fileChooser.getExtensionFilters().addAll(
      new ExtensionFilter("Audio Files", "*.wav", "*.mp3")); 
    File selectedFile = fileChooser.showOpenDialog(new Stage());   
    if (selectedFile != null) { 
     String fileName = selectedFile.getName(); 
     Table1.getItems().add(new PopulateTable(0, fileName, "")); 
    } 

} 

(Вы, возможно, потребуется изменить первый и третий значения параметров что-то подходящее.)
