I'm working on some Win32::GUI code, with no formal training, and just enough
OTJ to be really dangerous. I've come up against a couple of questions that I
cannot find answers to in my books. Here's the code:
#===============
sub Exit_Click {
#===============
MainWindow_Terminate();
}
#=========================
sub MainWindow_Terminate {
#=========================
print LOG "="x80 . "\n";
close( LOG );
return( -1 );
}
And here's the questions:
First, when Exit_Click (E_C) calls MainWindow_Terminate (MW_T), it does nothing
with the -1 that MW_T returns-or at least it looks that way (it is GUI, after
all, and I'm learning that GUI does a lot of, um, "invisible" stuff). So where
does that -1 go? Into the bit bucket? Or does GUI do some behind-the-curtain
prestidigitation with it? If this wasn't GUI code, I'd feel confident
believing that it's just ignored. But it is. So I don't.
Second: Is there some GUI-related requirement behind E_C calling MW_T instead
of doing, in its own code, the stuff MW_T does? That is, is there something in
the murky depths of Win32::GUI that's expecting a "thing" called Exit_Click to
call another "thing" called MainWindow_Terminate?
Thanks for sharing your wisdom.
