Esteemed monks,
It was time to add some colour choices to various things in my monster Perl/Tk application. So I added a simple little method using chooseColor, but alas it was a dismal failure. Oh, I could choose a colour alright, but alas, if you wanted to close the colour picker window ir click on the 'Cancel' button, it crashes the application.
Here is a minimal test case that I can make crash on my machine.
use strict;
use warnings;
use Tk;
my $cfg;
my $font_colour;
my $wd = MainWindow->new();
$wd->Label(
-text => 'Color',
-justify => 'right',
)->grid(
-column => 0,
-row => 4,
-pady => 20,
-padx => 20,
-sticky => 'e'
);
my $colour_button = $wd->Button(
-width => 6,
-command => sub { $font_colour = colour_picker() },
)->grid(
-column => 2,
-row => 4,
-pady => 20,
-padx => 20,
-sticky => 'e'
);
if ($font_colour) {
$colour_button->configure( -background => $font_colour, -activebackg
+round => $font_colour );
}
MainLoop;
sub colour_picker {
my $colour = $wd->chooseColor( -title => 'Color Picker', -initialcol
+or => '#000000' );
print "Colour chosen: " . $colour . "\n" if $colour;
$colour_button->configure( -background => $colour, -activebackground
+ => $colour );
return $colour;
}
In the event viewer the error is always:
Faulting application perl.exe, version 5.8.8.820, faulting module msvc
+rt.dll, version 7.0.2600.2180, fault address 0x000378c0.
I am using Perl 5.8.8.820 Activestate build, Windows XP-SP2.
I am not knowledgable enough to know how to troubleshoot this any further myself, so any assistance would be appreciated.
