When generating a multi view project with Gluon plugin for Ecplise, Netbeans or Intellij. It will be generating a view-class and a presenter-class. The view class looks like this for example:
public class ModelsView {
public View getView() {
try {
View view = FXMLLoader.load(ModelsView.class.getResource("models.fxml"));
return view;
} catch (IOException e) {
System.out.println("IOException: " + e);
return new View();
}
}
}
Is there some way I can access all the private fields in this controller models.fxml by just creating a code line like this:
View view = new ModelsView().getView(); // Here I am inside another controller
Can I access for example the getter method from the presenter-class by using the view object ? The view object is static as I can see it because there is no new before FXMLLoader.load(URL location)
public class ModelsPresenter {
@FXML
private View models;
@FXML
private @Getter TableView<String> tableView;
public void initialize() {
}
}
Heretic I am not using JavaFX from Gluon my configuration is jdk1.8.0_191 with derby in Netbeans 8.2 The code I am posting is my Model class PWData and the TableViewController just grabs the data from the derby DB The real important code is the initialize section of the TableViewController
public class PWData {
private final StringProperty ID;
private final StringProperty website;
private final StringProperty un;
private final StringProperty pw;
private final StringProperty sq;
private final StringProperty sans;
private final StringProperty notes;
public PWData(String ID,String website,String un,String pw,String sq,String sans,String notes) {
this.ID = new SimpleStringProperty(ID);
this.website = new SimpleStringProperty(website);
this.un = new SimpleStringProperty(un);
this.pw = new SimpleStringProperty(pw);
this.sq = new SimpleStringProperty(sq);
this.sans = new SimpleStringProperty(sans);
this.notes = new SimpleStringProperty(notes);
}
public String getID() {// 0
return ID.get();
}
public void setID(String ID){// 0
this.ID.set(ID);
}
public StringProperty IDProperty(){// 0
return ID;
}
public String getWebSite() {// 1
return website.get();
}
public void setwebsite(String website){// 1
this.website.set(website);
}
public StringProperty websiteProperty(){// 1
return website;
}
public String getUNName() {// 2
return un.get();
}
public void setun(String un){// 2
this.un.set(un);
}
public StringProperty unProperty(){// 2
return un;
}
public String getPW() {// 3
return pw.get();
}
public void setpw(String pw){// 3
this.pw.set(pw);
}
public StringProperty pwProperty(){// 3
return pw;
}
public String getSQName() {// 4
return sq.get();
}
public void setsq(String sq){// 4
this.sq.set(sq);
}
public StringProperty sqProperty(){// 4
return sq;
}
public String getSANS() {// 5
return sans.get();
}
public void setsans(String sans){// 5
this.sans.set(sans);
}
public StringProperty sansProperty(){// 5
return sans;
}
public String getNotes() {// 6
return notes.get();
}
public void setnotes(String notes){// 6
this.notes.set(notes);
}
public StringProperty notesProperty(){// 6
return notes;

I am a little unsure of what you are trying to do but I would suggest you focus on the use of ObservableValue and Listeners You can download the entire code
