Detection of an event in a library routine

[Zaxon]

I have a common library function in which I need to detect whether it has been triggered by an event, or simply called directly in a script.

So far, any testing of the macros set during an event, error out the program if used.

For instance, an equivalent to IsDeclared(@GUI_WINHANDLE) used for testing variables does not work for testing macros. Nor can you test for @error, since any reference to an event macro will error the program out entirely, causing it to stop.

So in summary, I need this functionality:

func some_library_routine()
    if some_test(@GUI_WINHANDLE) then
        blah
    else
        blah
    endif
endfunc

where my question is, what test can I use to determine whether this function was triggered via an event, or called directly?

As my question slips onto page 3 of this forum without an answer, do I assume this cannot be done?

You could give it a paramater that you set differently based on how you are calling it:

ie

Calling it in the script:

some_library_routine(0)

Calling it from a windows event:

$msg = GUIGetMsg()

if $msg = $hbutton then some_library_routine(1)

Indeed. I'd thought about that, but I was hoping that my library function could be truly polymorphic, by which I can only achieve that transparency if the function can internally check who called it.

Still, if I have no full solutions, then I'll do precisely that, and pass a parameter in manually.

Thanks for the input.
