2 questions regarding Button and touch event

Thanks a lot everyone for your quick replies here.

@allobjects : Yes, that is what I was exactly thinking about now. I would eventually have many more app icons here so plan to show each app icon with a right swipe and like a scroll , I will then show the following icons too.

@fanoush : Thanks, I have never used a smartwatch myself, so probably you are right. Because of the use of smart phones and touch screens, I assumed that the app icons have to be touched to open them. I thought that would be very natural for any user to do so. Hence I thought that it was something very basic. But as you say, probably the user works differently with a smartwatch.

@Gordon : Thanks a lot!

but you could highlight a key, then use BTN1/3 to move up/down, then the touch areas to move left/right and BTN2 (in the middle) to select.

Can I do this in the emulator? Highlighting of the key and then selecting using the BTN2 ?

Thanks everyone once again!
