Hi,

I have overriden a onTouch event for my container. What I want basically

is to respond to "clicks" on my container (just like button clicks). How

to achieve similar functionality to a "click" using the onTouch????

I mean how to know, using an onTouch, that an action similar to "click" has occured???

When I have purely

onTouch { .. some action ... }

 I think this gets called twice, once when the user clicks the container area, and second time, once the user

releases the mouse button.

What about using the TapHandler as a gestureHanlder on your container ... works fine for my usecase.

Container{

gestureHandlers: [
            TapHandler {
                onTapped: {
                        ... some action ...

                   }
                }
            }
        ]

}

I am not sure which is better, more common. I guess i will have a look at both. btw. OnTapped -- is it similar to a "clicked" event? e..g, like with buttons? thanks.

As far as i'm aware, there is no "up" or "down" state like you have with the onTouch (cfr your calling twice of the event), but do correct me if i'm wrong ("new" developer on this OS).

More info can be found here: http://developer.blackberry.com/cascades/documentation/dev/touch/index.html

You can also add DoubleTapHandlers and LongPressHandlers to differentiate various scenario's/gestures.

Hi,

These events can be differentiated:

onTouch: {
  if (event.isDown()) {
    // ...
  }
}
