Drupal – Panel Pane Title Translation @ 1

In Panel page, we can configure the pane title at the content page.

By default, we could not translate these pane titles in Translate Interface. To fix this problem, we can override the template variable before rendering the panel pane. This could be done by add the template_preprocess_panels_pane() function in the theme template.php

function <theme>_preprocess_panels_pane(&$vars) {
    $content = $vars['output'];
    $vars['title'] = !empty($content->title) ? t('@title', array('@title' => $content->title)) : '';
}

Reload the panel page in the translate content first, then you can find the pane title in the Translate Interface.
