Detailed Description
The result of a pick action.
Member Function Documentation
◆ operator()()
|
inline |
Convenience function to return the touch index at the given coordinates (x,y).
It will return an invalid number (-1) if there is no picklist here.
Calling this function is inefficient because it performs a null pointer check for the picklist at each call. It is more efficient to call the TouchArea() function once and use its linear pointer instead.
