Check entry if it empty

[csudess]

How could i check the entry when is empty or not?

Could you explain what you mean by "entry"?

 

[csudess]

perl entry?!
this is a sample entry code so this is the entry

$ent=$mw->Entry(-width=>4,
-font=>"arial 10 bold"
);

Something like this:

&checkempty($username,"Your name cannot be blank.");

Would you mean:

$ent=$mw->Entry(-width=>4,                
                -font=>"arial 10 bold"
               );
if ($ent) {
     #not empty
}
else {
     #empty
}

Thank u for ur answers i found the right code which is:

use strict;
use warnings;
use 5.010;

my $entry = '';

if ($entry eq '') {
say '$entry is blank';
}
else {
say '$entry might be undef';
}
