Widgets files

All the widgets are registred in wp-content\plugins\wpresidence-core\widgets.php

if( !function_exists('register_wpestate_widgets') ):

function register_wpestate_widgets() {
wpestate_widgets_init();
register_widget('Tweet_Widget');
register_widget('Facebook_Widget');
register_widget('Mortgage_widget');
register_widget('Contact_widget');
register_widget('Social_widget');
register_widget('Featured_widget');
register_widget('Footer_latest_widget');
register_widget('Advanced_Search_widget');
register_widget('Zillow_Estimate_Widget');
register_widget('Login_widget');
register_widget('Social_widget_top');
register_widget('Featured_Agent');
register_widget('Multiple_currency_widget');
}

Each widget is in a separate file (in wp-content\plugins\wpresidence-core\/widgets folder) included like this

require('widgets/twiter.php');

The name of the files are self-explanatory.
