How to pass parameters to JavaFX application?

Question

I am running my JavaFX application like this:

public class MainEntry {
    public static void main(String[] args) {
        Controller controller = new Contr         


        

Answer 1

case 1 = java standard types - transmit them as java Strings "--name=value" and then convert them to the final destination using the answer of dmolony

          for ( Map.Entry entry : namedParameters.entrySet ()){
            System.out.println (entry.getKey() + " : " + entry.getValue ());              
            switch( entry.getKey()){
            case "media_url": media_url_received = entry.getValue(); break;
            }
      }

The parameter is created at Application.launch and decoded at init

String args[] = {"--media_url=" + media_url, "--master_level=" + master_level};
Application.launch( args);

case 2 = If you have to transmit java objects use this workaround (this is for only one javafx Application launch, create a Map of workarounds and send index as strings if you have a complex case)

    public static Transfer_param javafx_tp;

and in your class init set the instance of object to a static inside it's own class

    Transfer_param.javafx_tp = tp1;

now you can statically find your last object for working with only one JavaFx Applications (remember that if you have a lot of JavaFx applications active you should send a String with a static variable identification inside a Map or array so you do not take a fake object address from your static structures (use the example at case 1 of this answer to transmit --javafx_id=3 ...))
