Hi Anonymous, thanks for replying so quickly. Actually, I had seen that sample code previously, and had downloaded and run it, and found that although it displayed amazing graphics, it too did not respond to my mouse clicks. I also noticed that it did not have a $console -> Alloc () instruction anywhere, which I initially thought might be why neither it nor my program responded to mouse events, because I did not have a $console -> Alloc either. However, when I added a $console -> Alloc () instruction to my code, the window in which my program was running would instantly vanish as soon as the $console -> Alloc instruction was reached. So I fiddled with $console -> Free () with it for a while, to no avail, and finally removed the $console -> Alloc instruction again.

I have now revised my code to eliminate the 1-second sleep. By commenting one instruction or not, I can make it sleep only a hundredth of a second or not sleep at all, with the results being the same, viz. no mouse events are detected. This is the revised code:

use strict;
use warnings;

use Time::HiRes qw (usleep);

use Win32;
use Win32::Console;

my $console;
my @console_event;

undef $/;

unless ($console = new Win32::Console STD_INPUT_HANDLE)

    {
        print STDERR "\nSomething has gone wrong with the Win32::Conso
+le constructor: $!\n\n";
        die;
    }

$console -> Mode (ENABLE_MOUSE_INPUT);

print "Perl version $^V running on ", join (" ", Win32::GetOSName), ".
+\n\n";

print "Your mouse has ", $console->MouseButtons(), " buttons.\n\n";

print "Go ahead, make my day ...\n\n";

my $start_time = time ();
my $when_to_stop_waiting = $start_time + 15;

while (time () < $when_to_stop_waiting)

    {
        if ($console -> GetEvents ())

            {
                @console_event = $console -> Input ();

                print "A console event has been detected.  Its attribu
+tes are the following:\n\n";

                print "$_\n" for @console_event;

                print "\nGood job.\n";

                exit;   #   exit the program, do not fall through to t
+hat final print instruction
            }

         else

            {
                usleep 100;     #   sleep for 10 milliseconds, i.e. a 
+hundredth of a second, to prevent
                                #   this program from getting into a r
+eally tight loop and crowding out
                                #   everyone else, but even without th
+is usleep instruction the mouse
                                #   clicks are still not detected
            }
    }

print "The time to stop waiting has been reached. Your input was not d
+etected.\n";
print "Better luck after seeking the wisdom of the monks.\n";

When I run this revised version and press any key, the following is generated:

Go ahead, make my day ...

A console event has been detected.  Its attributes are the following:

1
1
1
70
33
102
32

Good job.

But as before, I can click on the mouse all night, and this is what is generated:

H:\sandbox>perl capture_mouse_events.pl
Perl version v5.32.0 running on Win10 Build 18363 (64-bit).

Your mouse has 16 buttons.

Go ahead, make my day ...

The time to stop waiting has been reached. Your input was not detected
+.
Better luck after seeking the wisdom of the monks.

I've thought about re-writing my application in Win32::GUI but it would involve writing a lot more code creating and managing the window entirely within the program, not just hooking into a pre-existing console as with Win32::Console.
