Checkbox prop style problem

[corvinsoft-tothzs]

Hi!

I want generate checkbox with pipe style, but not working.

i read: https://www.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/js_api_reference.pdf

my code:

$prop = [
    'style' => 'cr'
];

 $pdf->CheckBox('newsletter', 5, false, $prop, array(), 'OK1', 600/5, 500/5, false);

Am I spoiling something or seriously not working?

Try the 2015 version instead of the 2007 one first: https://wwwimages2.adobe.com/content/dam/acom/en/devnet/acrobat/pdfs/AcrobatDC_js_api_reference.pdf

Also, where is the "cr" declaration in the linked doc? Searching for it reveals nothing.

Thanks for answer!

My doc: 443page, Ur doc: 439 page

I tried: style.cr too, but not working.

Thanks. As far as I understand that, style.cr is not a string, it is a reference to style's object variable, so try the actual Style names: e.g. "cross" or "diamond" instead.

I'm also unsure if TCPDF actually supports this, look at this is the code by the way (the file seems too large for Github to index), the cr key doesn't seem to be used:

        /**

     * @param $name (string) field name
     * @param $w (int) width
     * @param $checked (boolean) define the initial state.
     * @param $prop (array) javascript field properties. Possible values are described on official Javascript for Acrobat API reference.
     * @param $opt (array) annotation parameters. Possible values are described on official PDF32000_2008 reference.
     * @param $onvalue (string) value to be returned if selected.
