SYNOPSIS

  package MyApp::Controller::Images;

  use base 'CatalystX::Controller::ExtJS::Image::Chooser';

  __PACKAGE__->config(
      {
          image_chooser_dir => 'root/static/images',
          image_chooser_url => '/static/images'
      }

DESCRIPTION

Top

This module generates an object which can be serialized to a json string. The ImageChooser class of ExtJS expects the data in this way.

You can even look in subdirectories by simply adding the directory name to the url. Example: /images/subdir gives you the files from root/static/images/subdir. You cannot access directories, which are parents of the base directory.
