I had the same issue today and found this thread. Yes, it is old, but I would like to add another solution in case someone needs it.

You can use a timer to wait for a moment before you do the resize. Cancel the timer if the MainWindow resizes again within a certain time and start it anew.

Sample code:

#!perl use strict; use warnings; use Tk; use v5.16; # Skript zum manuellen resizen der Canvas nach Änderung der Größe des +MainWindow. # Man muss nochmal einen Rechtsklick machen. # Quelle: https://www.perlmonks.org/bare/?node_id=581309, abgerufen 20 +20-11-21 my $mw = Tk::MainWindow->new; my $current_size = $mw->reqwidth . "x" . $mw->reqheight; my $old_current_size = $current_size; my $canvas = $mw->Canvas( -width => 300, -height => 300, -bg => 'black', )->pack(); $canvas->update; # important to call this before binding <configure> e +vent my $after_resize_timer_id; $mw->bind('<Configure>' => sub { say "MW resized"; # reset timer again, if it was set $mw->afterCancel($after_resize_timer_id) if defined $after_resize_ +timer_id; # set timer # if MW doesn't resize again within a second or so, resize Canvas # if it does, reset timer to wait for a second or so $after_resize_timer_id = $mw->after(500, sub{ say "Update canvas"; my $width = $mw->width; my $height = $mw->height; $canvas->configure(-width => $width, -height => $height); $canvas->update; }); }); $mw->MainLoop; exit(0);

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
