I'd like to keep the javascript and css styles used by my widget inside their own files (and not add them to the theme).

But i can't seem to get wordpress to add them when the widget is actually used on a sidebar.

I've tried this:

inside the Class declaration, i've added 2 functions

class EssentielleRubriquesPosts extends WP_Widget {

function addFrontendCss(){
    wp_enqueue_style('erw-frontend-css', ESSENTIELLE_RUBRIQUE_WIDGET_PLUGIN_PATH . 'css/EssentielleRubriqueWidget-frontend.css');
function addFrontendJavascript(){
    wp_register_script('jq-hoverintent', PLUGIN_PATH . 'js/jquery.hoverintent.js', array('jquery'), '1.0',true);
    wp_enqueue_script('jq-tools', PLUGIN_PATH . 'js/jquery.tools.js', array('jquery'),'1.0',true);
    wp_enqueue_script('erw-frontend-js', PLUGIN_PATH . 'js/widget-frontend.js', array('jquery', 'jq-hoverintent', 'jq-tools'),'1.0',true);


and inside the widget() function:

function widget($args, $instance) {
        add_action( 'wp_print_scripts', 'addFrontendJavascript' );
        add_action( 'wp_print_styles', 'addFrontendCss' );

But that doesn't do anything...

wp_print_scripts and wp_print_styles hooks are fired way before your widget function so that is way it's not working.

A solution to that would be to include the scripts in the footer using wp_print_footer_scripts hook, take a look at Jan's answer to a similar question

Or a much nicer solution take a look at Sorich's answer to another similar question
