Example 3 with IconSpec

use of org.eclipse.scout.rt.client.services.common.icon.IconSpec in project scout.rt by eclipse.

the class BinaryResourceUrlUtility method createIconUrl.

/**
 * @return a relative URL for a configured logical icon-name or a font-based icon. For instance:
 *         <ul>
 *         <li>input: <code>"bookmark"</code>, output: <code>"icon/bookmark.png"</code> (the file extension is
 *         included to support auto-detection of the MIME type without looking at the file contents)</li>
 *         <li>input: <code>"font:X"</code>, output: <code>"font:X"</code></li>
 *         </ul>
 *         The file extension is included to be able to auto-detect the MIME type based on it.
 *         <p>
 *         Use this method for image-files located in the /resource/icons directories of all jars on the classpath.
