Hi,

what do you want to know?

Any variable/attribute can also contain action-code and so also can be called.

e.g. set the 'test' variable to some action code:

Code

set(test, 'trace(hello); trace(from test);' );

and then call it:

Code

test();

This is how the 'opened_onclick' setting was used in the vtourskin.xml for the skin_logo element.

Best regards,
Klaus

thanks klous. i understand. it is possible to call a variable like a funcition (with "()") when the variable contains other actions.

thanks
