Apps Function that returns pixel touched

[alexenduro]

Hi everibody! As title, i need a function that returns the pixel that i'm touching...
for example i have an image in background and i want that, if i keep touching a point for a little bit, it appears a menu where i can do something on that exact position like adding a draw on the picture in background...

already exists a function like that? thanks!
