in thread Tk::Entry not updating when textvariable changes.

I'm suspicious of Config::IniHash myself... I'm operating under the assumption that the $cini_global is a hashRef, and I know that getOpenFile returns a scalar -- in this case a selected filename. Here's a shortened example:

use Tk; use strict; $::cini_global = { trickle => { email_template_file => "nothing" }}; my $mw = MainWindow->new; $mw->Entry( -width => 40, -textvariable => \$::cini_global->{trickle}->{email_template_file} )->pack(qw/-expand 1 -fill x/); $mw->Button( -text => "Change", -command => sub { $::cini_global->{trickle}->{email_template_file} = $mw->getOpenFile(); })->pack; MainLoop;

I suspect there's something else going on outside of the shown code. Perhaps Config::IniHash creates something different than what it appears

Update: It would seem that Config::IniHash does some pretty interesting things under the hood and isn't exactly what it seems. I haven't looked at all the code, but my guess is that the two times you use it, the internal references are different. I've added a second example that shows how I'd work around it if I had to use Config::IniHash, which I'm not certain that I would.

<crotchety voice>Config::IniHash seems a bit too clever for its own good to me</crotchety voice> Still, its code makes for pretty interesting reading ;-)

Example 2 : In the second example I was able to reprodce the reported problem. The code shows how I worked around it.

config file, containing:

[trickle] email_template_file=nothing

Script with workaround:

use strict; use Config::IniHash; use Data::Dumper; use Tk; $::cini_global = ReadINI 'config'; my $ref = $::cini_global->{trickle}->{email_template_file}; my $mw = MainWindow->new; $mw->Entry( -width => 40, -textvariable => \$ref )->pack(qw/-expand 1 -fill x/); $mw->Button( -text => "Change", -command => sub { $ref = $mw->getOpenFile(); $::cini_global->{trickle}{email_template_file} = $ref; })->pack; MainLoop;
