Turing button confusion

[compnerd101]

When incorporating buttons into turing programs, why is it nessesary to add the:

loop
exit when GUI.ProcessEvent
end loop

why is that chunk of code nessesary for buttons to work?

[Beastinonyou]

Well, it doesn't have to be, if you make your own buttons.

all you need to make your own button is:

1. Mouse.Where (x, y, b) % X, Y, Mouse State
2. Co-ordinates (x1, y1, x2, y2) % Bottom Left to Top Right
3. Something to do when the User clicks Between your Co-ordinates

But to answer your question, it is what makes the button "press-able".

It basically handles all the work of checking if the button has been pressed, and responding if it has.
