No key event is generated from mac book pro trackpad

I'm developing an application in javafx multiltouch on mac, but no key event was taken by the Manager using the trackpad. Event handlers are added to the scene.

I use JDK1.7.0_07.

Someone has an idea.

Thank you.

I don't think it will work. The javadocs for the TouchEvent explicitly state

"Touch event indicates a touchscreen action."

The trackpad isn't a touch screen.

The trackpad will generate GestureEvents. Once again, since the javadocs:

"Actions are usually caused by direct (touch screen) or indirect (track pad) touch events."

If you can handle things like ScrollEvent, RotateEvent and ZoomEvent. I think that the mapping between the physical gestures on the trackpad and semantic events is managed by the operating system (if the behaviour could change if the user changes the settings for trackpad in system preferences, for example). It doesn't look like it will answer to your needs, but maybe...

I don't know if there is another way to interact with the trackpad (someone else surely will).

Here is a simple way to see which events are generated (it will generate a lot of output).

import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.input.InputEvent;
import javafx.scene.layout.AnchorPane;
import javafx.stage.Stage;

public class TouchTest extends Application {

  @Override
  public void start(Stage primaryStage) throws Exception {
    Scene scene = new Scene(new AnchorPane(), 400,400);
    scene.addEventHandler(InputEvent.ANY, new EventHandler() {
      @Override
      public void handle(InputEvent event) {
        System.out.println(event.getEventType().getName());
      }
    });
    primaryStage.setScene(scene);
    primaryStage.sizeToScene();
    primaryStage.show();
  }

  public static void main(String[] args) {
    launch(args);
  }

}

I have a new mac book pro, I need to copy my stuff from my old mac pro book

Hi all, I just splashed the money and got myself a new mac book pro, without the DVD player.

Now I would like to transfer all my stuff from my old book of mac pro, the easiest way and fastest possible.

while I was in the store to spend my money, the guy told me that I can do by connecting two computers together via Firewire/stroke of lightning and using Time Machine!

I have an adapter Firewire/Thunderbolt and a Firewire cable :-)

But I would like to have someone, somewhere to point me in the right direction so that I'm not kidding, I did it this way before, are there details step by step anywhere please, I don't can find any info anywhere else!

Thanks for looking and if you can help/advise so much better :-)

How can I transfer contacts from galaxy s4 for Mac book pro?

I recently bought a Mac book pro 15 ".

I need to transfer contacts and some files on my new mac.

How can I do?

TKS for your help

Ottavio

Hey ottaviob,

If I understand correctly, you want to transfer contacts and other things to your new Mac.
I recommend you to read this article; It has advice to transfer your contacts, music, photos, documents and more on your Android device. Once the content is on the Mac later at some point if you wish, this article is also not to transfer this content in an iOS device too.

On a Mac, install Android File Transfer, open it,
