Hi,
I just finishe developing a user app using Tk and now I have to fix one strange behaviour (by strange I mean: that which I do not understand).
I have a loop that executes on a button callback and it executes a function and depending on the data returned by the function I have to show some things on the app window.
Thing is: when the loop is being executed, and I change the text of a Label object, it does not "change" instantly. It is as if the loop blocks the app (if I put other windows on top of it, it is not redrawn). Here is a piece of the code, edited to fit here:
$err = $SiTef->ExecutaLoopAutorizacao( $SiTef, $params, $data );
while ( $err eq '10000' ) {
#print Dumper( $params, $data );
#print "\nRETORNO: $err\n";
if ( $params->{UserMessage} ) { $Status = $params->{Message}; }
$err = $SiTef->ExecutaLoopAutorizacao( $SiTef, $params, $data );
}
the GUI has this label:
my $Status;
my $lblStatus = $mw->Label(-textvariable=>\$Status)->pack();
Is there something Im not getting about Tk programming, is there an easy way to fix this or should I go somewhere else?
