DESCRIPTION

A LibUI::PasswordEntry object represents a control with a single line text entry field.

The entered text is NOT readable by the user but masked as *******.

This is a subclass of LibUI::Entry.

Functions

Not a lot here but... well, it's just a text box.

new( ... )

            

              
              
my $txt = LibUI::PasswordEntry->new( );
            
          

Creates a new entry.

onChanged( ... )

            

              
              
$txt->onChanged(
sub {
    my ($ctrl, $data) = @_;
    warn $ctrl->text;
}, undef);
            
          

Registers a callback for when the user changes the entry's text.

Expected parameters include:

$callback - CodeRef that should expect the following:

$txt - backreference to the instance that initiated the callback

$data - user data registered with the sender instance

$data - user data to be passed to the callback

Note: The callback is not triggered when calling setText( ... ).

readonly( ... )

            

              
              
if( $txt->readonly( ) ) {
    ...;
}
            
          

Returns whether or not the entry's text can be changed.

setReadonly( ... )

            

              
              
$txt->setReadonly( 1 );
            
          

Sets whether or not the entry's text is read only.

setText( ... )

            

              
              
$txt->setText( 'Updated' );
            
          

Sets the entry's text.

text( ... )

            

              
              
warn $txt->text( );
            
          

Returns the entry's text.
