HI all , I workaround this problem doing a change of the background of the button at the begining and the ending of the -command action. As the -command action is relatively long this work in an acceptable way. From a logic point of view:

-command => sub {

my $caller_ = $Tk::widget;
$caller_->configure(-bg ='red');
$caller_->update; 
........................
.....long operation on db

$caller_->configure(-bg ='grey');
$caller_->update; 
}

This work quite well for my needs . Thank a lot
