<title>Description</title>
<para>A <link
linkend="class-gtktextmark"><classname>gtk.TextMark</classname></link> is
like a bookmark in a textbuffer - it preserves a position in the text. You
can get an iterator corresponding to a textmark by using the <link
linkend="method-gtktextbuffer--get-iter-at-mark"><methodname>gtk.TextBuffer.get_iter_at_mark</methodname>()</link>
method. Unlike iterators, textmarks remain valid across buffer modifications
(e.g. when text is inserted or deleted). When text containing a textmark is
deleted, the textmark remains in the position originally occupied by the
deleted text. When text is inserted at a textmark, a textmark with left
gravity will be moved to the beginning of the newly-inserted text, and a
textmark with right gravity will be moved to the end. Textmarks optionally
have names that can be used to avoid passing the <link
linkend="class-gtktextmark"><classname>gtk.TextMark</classname></link>
object around. Textmarks are typically created using the <link
linkend="method-gtktextbuffer--create-mark"><methodname>gtk.TextBuffer.create_mark</methodname>()</link>
method. A <link
linkend="class-gtktextbuffer"><classname>gtk.TextBuffer</classname></link>
has two built-in <link
linkend="class-gtktextmark"><classname>gtk.TextMark</classname></link>
objects named: <literal>insert</literal> and
<literal>selection_bound</literal> which refer to the insertion point and
the boundary of the selection (these may refer to the same location).</para>

visibility of the textmark to the value specified by

insertion point is normally visible but most textmarks are not visible by
default. The text widget uses a visible textmark to indicate where a drop
will occur when dragging-and-dropping text.</para>
