Flashing a GUI button using Perl & Ttk on a Mac

QUESTION

Flashing a GUI button using Perl & Ttk on a Mac

Asked 2021-May-31 at 11:29

Using Perl v5.28, Tkx.pm v1.10 with ActiveState Tcl/TTk v8.6.9 ('aqua' style), on macOS v10.13.6. The demo below works as desired, enabling the calling of a given subroutine using either a GUI button push using the mouse, or using keyboard input with a 'normal' text character.

The one additional feature I would like to have is the visual feedback of the graphical button being pressed (flashing) when the keyboard alternative activation is used. I found what looks like a Tcl solution using the event generate command, and a reference on using the Perl Tkx::event_generate() virtual event method call. I even found the equivalent Perl Tkx::after(100) function call to create the suggested delay. But I can't wrap my head around how to put this all together to achieve the desired effect. Any help would be appreciated, with the understanding that, like some other TTk features, this might not work on the Mac.

Here is an example (tested on Ubuntu 21.04). By calling g_event_generate("") on the button, invoke() will be automatically called on the button:

Why does perl qx hang in Mojolicious::Lite but not in an ordinary program?

Asked 2020-Jul-30 at 17:53

(This is cperl 5, version 24, subversion 4 (v5.24.4c) built for x86_64-linux) Ubuntu 18.04.

Below is a program that works. However, when I run this program from within Mojolicious::Lite (version 6.04), it hangs. Using top, I see that "tr" is the one eating all the CPU. I have tried using cat instead of tr and it still hangs. If I Control-C the Mojo code it prints the password then exits. It is like tr is accepting the urandom bytes but not moving on to the fold until I interrupt it. But, this works in the ordinary script, not the Mojo one...

Anyone any ideas as to why?

I am not sure why tr hangs when directly taking input from /dev/urandom. I was able to work around it by having an intermediate cat pipe before the tr. The following works for me:

According to the documentation:

Usage: perlbrew available [--all]

List the recently available versions of perl on CPAN.

The list is retrieved from the web page http://www.cpan.org/src/README.html, and is not the list of all perl versions ever released in the past.

To get a list of all perls ever released, use the --all option.

so you can use:
