CurrentElement() -get pointer of current element in save way
Posted: Thu Jun 05, 2014 9:10 am
There are some save functions to get pointers:
- FirstElement() - returns the pointer of first element or zero
- NextElement() - returns the pointer of next element or zero
- PreviousElement() - returns the pointer of previous element or zero
I serach a function like that:
- CurrentElement() - returns the pointer of current element or zero
At the moment, the only way to get the pointer of the current element (@list) is not save. You have to use ListIndex() to prevent errors:
- FirstElement() - returns the pointer of first element or zero
- NextElement() - returns the pointer of next element or zero
- PreviousElement() - returns the pointer of previous element or zero

Code: Select all
Macro CurrentElement(mypointer, mylist)
If ListIndex(mylist) = -1: mypointer = 0: Else: mypointer = @mylist: EndIf
EndMacro
NewList test()
CurrentElement(*pointer, test())
Debug *pointer
AddElement(test())
CurrentElement(*pointer, test())
Debug *pointer
ResetList(test())
CurrentElement(*pointer, test())
Debug *pointer
