Java Question

how to insert into a table the file name loaded with filechooser in javaFX?

I'm trying to populate the table with the file name taken by filechooser, in fileName column, how can I include the filename in this column of Tableview ?

this is a Interface with sceneBuilder

this is a utility class PopulateTable

package utility;

import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;

public class PopulateTable {
private final SimpleIntegerProperty count;
private final SimpleStringProperty name;
private final SimpleStringProperty date;
public PopulateTable(int count, String name, String date) {
super();
this.count = new SimpleIntegerProperty(count);
this.name = new SimpleStringProperty(name);
this.date = new SimpleStringProperty(date);
}
public int getCount() {
return count.get();
}
public String getName() {
return name.get();
}
public String getDate() {
return date.get();
}
}

Answer

Just do

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

i.e.

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, ""));
    }

}

(You might need to change the first and third parameter values to something appropriate.)
