7 * Anchorblock is for displaying text that contains markup with anchors
8 * like <c>\<a href=1234\>something\</\></c> in it.
10 * Besides being styled differently, the anchorblock widget provides the
11 * necessary functionality so that clicking on these anchors brings up a
12 * popup with user defined content such as "call", "add to contacts" or
13 * "open web page". This popup is provided using the @ref Hover widget.
15 * This widget emits the following signals:
16 * @li "anchor,clicked": will be called when an anchor is clicked. The
17 * @p event_info parameter on the callback will be a pointer of type
18 * ::Elm_Entry_Anchorblock_Info.
24 * Since examples are usually better than plain words, we might as well
25 * try @ref tutorial_anchorblock_example "one".
