Perl/Tk - Tk::Clock

by PERLscienceman (Curate)
on Jul 17, 2003 at 02:53 UTC ( #275094=CUFP: print w/replies, xml ) Need Help??

At work I code by the ton. At home I could for fun; experimenting with Tk and whatever other cool modules I might happen to stumble upon; to learn new things and tinker around with that which is cool (which would be just about anything PERL)

This time it is about as simple as it gets. Poking around the world of CPAN I found the module Tk::Clock. In a nutshell, this Tk module generates a digital clock face, analog clock face or both. I decided to assemble the script so that it generated a "BIG classic analog clock". The module allows for manipulation of the colors of the hands and tick marks. In addition, in this particular script, I have played around restricting resizing of the Tk GUI (I read about it in one of the major Perl Books). Anyway enough said. The code is posted below.

As always, any feedback is greatly appreciated! Enjoy!

#!/usr/bin/perl -w use Tk; use Tk::Clock; my $MW=MainWindow->new(); ### --- Prevents Main Window Resizing $MW->bind('<Configure>' => sub{ my $xe = $MW->XEvent; $MW->maxsize($xe->w, $xe->h); $MW->minsize($xe->w, $xe->h); }); $MW->title("My Analog Clock"); $clock = $MW->Clock(); $clock->config( useDigital => 0, useAnalog => 1, anaScale => 880, handColor => 'Green4', secsColor => 'Red2', tickColor => 'Black', ); $clock->pack(); MainLoop();

    Hi, yeah, I've adopted tk-clock along time ago for my clock. I have a very minimalist desktop, and all I wanted was a tiny digital clock in the lower right hand corner. It also stays on top across my 10 virtual desktops. I've shown how to cut off the date too. I have a 1024x768 desktop, so you may have to adjust the geometry for your desktop.
    #!/usr/bin/perl use Tk; use Tk::Clock; my $m = MainWindow->new(); #$m -> geometry("70x30+930+740"); #with date $m -> geometry("70x15+940+755"); #no date $m->overrideredirect(1); #no xterm decorations my $c = $m->Clock (-background => "Black"); $c->config ( useAnalog => 0, useDigital => 1, # tickColor => "Orange", # handColor => "Red", # secsColor => "Green", timeColor => "lightBlue", # timeFormat => "hh:MM A", timeFormat => "HH:MM:SS", # dateColor => "Gold", # dateFormat => "m/d/y", timeFont => "-misc-fixed-medium-r-normal--13-*-75-75-c-*-iso8859- +1", ); $c->pack; MainLoop;
      Greetings! Thank you for your response. Since you mentioned small digital clocks based on Tk; here is another one, even simpler than the first. It is based on the Tk::StrfClock module. All of about 6 lines of code to get it going, it generates a small Tk Widget with date and time.

      Here is the code, very simple. Enjoy!

      #!/usr/bin/perl -w use Tk; use Tk::StrfClock; my $top=MainWindow->new(); $top->StrfClock()->pack(); MainLoop();
        Hey that last (short one) looks like a winner. However, I don't see it in the ActiveState list. Thats where I get my modules from for Win32 system.

    Found Tk::Clock a few minutes ago on CPAN. Did a search to see if anyone had an example implementing it... ended up here. Looks cool. Was looking for a way to have a graphical clock. I looked into the Time() modules, but they basically only provide a time-stamp, no continous time. This module works great.
