Stupid Mac::Glue Tricks: Leopard Spaces

[ #34825 ]

So a lot of times when using Spaces under Leopard, windows just ... disappear. They are not visible in any space. So I have to open up the System Preferences and turn Spaces off, and then back on, which fixes it.

Here's a script that I put in my Script Menu (~/Library/Scripts/Reset Spaces.scpt) so I have quick access to it.

tell application "System Events"
    set (spaces enabled of spaces preferences of expose preferences) to false
    set (spaces enabled of spaces preferences of expose preferences) to true
end tell

Oh. You want a Perl version, do you?

Fine.

#!/usr/bin/perl
use warnings;
use strict;
 
use Mac::Glue;
 
my $sysevt = new Mac::Glue 'System Events';
 
my $enabled = $sysevt->prop('spaces enabled',
    of => 'spaces preferences',
    of => 'expose preferences'
);
$enabled->set(to => 0);
$enabled->set(to => 1);

I prefer AppleScript for stuff like this, since it's quicker to execute and I have to use AppleScript to figure out how to do it in Perl anyway, since AppleScript is sometimes easier to prototype with when you don't know what properties and objects you're working with. But it took only a minute to convert it to Perl, so no biggie.

System Events in Leopard has a lot of new junk in it for scripting preferences. Pretty neat, you can script many difference preferences now. Here's a list.
