I know the "difference", but what exactly is the point?
I made an app. A button implements both Click and Tapped. I have a Touchscreen PC (yay I bought it yesterday!), and I tapped the button with my finger (when I had only implemented Click handler) - and it worked. I then implemented Tapped handler, and I then clicked the button with my mouse. And it worked.
So, both work in both scenarios.
Is Click only to be used for backwards compatibility? That's the only reason I can think of to use both. But my question is, do we need to have both handlers for every interaction in our apps?
