/* This is intended to serve as a common widget for previews before import.
 * It contains a GtkTreeView at the top and an EWebView at the bottom.
 * The tree view is not shown initially, it should be forced with
 * e_web_view_preview_show_tree_view().
 *
 * The internal default EWebView can be accessed by e_web_view_preview_get_preview()
 * and it should be updated for each change of the selected item in the tree
 * view, when it's shown.
 *
 * Updating an EWebView content through helper functions of an EWebViewPreview
 * begins with call of e_web_view_preview_begin_update(), which starts an empty
 * page construction, which is finished by e_web_view_preview_end_update(),
 * and the content of the EWebView is updated.
