How to load text into Curses::UI::TextEditor -> -text?

Guys,

I'd like to write a perl-based tool that helps me to
do my regular system monitoring tasks.
It would be running in console mode but using
'windows' to list the command outputs.

Curses::UI::TextEditor would be one of the elements
that I use to present the output in a nice formatted
way.

It appears to me that its -text option is not
accepting strings from a function but only static
texts.

Is there anyone here who already had to struggle with
this module before?

Sorry if it's an off-topic email here, I really don't
know where to ask my question.

Thanks in advance!

Regards,

John

Here's an example:

$w{202}->add(
undef, 'TextEditor',
-title => 'Disk
space',
-y => 0, -padright =>
0, -border => 1,
-padbottom => 0,
-readonly => 1,
-vscrollbar => 1,
-hscrollbar => 1,
-text => $text,
);

The variable $text has only a simple string value
something like "This is a test...", but when I run the
code the TextEditor only present '1'.

If I try to use the function like this

-text => \&fs_check,

The the result is 'CODE(0x972e3c4)'

It only works if I write a static string next to text:

-text => "This is a test..."

You assigned a reference to a subroutine, and it's address is correctly shown,
since the value of this attribute is not called by the code but displayed
literally.

You probably want to assign the result string of a call of the subroutine:

-text => fs_check(),

Does this help?
