How do I make a text view scroll to the end of the buffer automatically ?

The "insert" <link linkend="GtkTextMark">mark</link> marks the insertion point
|

where <link linkend="gtk-text-buffer-insert">gtk_text_buffer_insert()</link>
|
||||
inserts new text into the buffer. The text is inserted
|
||||
<emphasis>before</emphasis> the "insert" mark, so that it generally stays
|
||||
at the end of the buffer. If it gets explicitly moved to some other position,
|
||||
e.g. when the user selects some text,
|
||||
use <link linkend="gtk-text-buffer-move-mark">gtk_text_buffer_move_mark()</link>
|
||||
to set it to the desired location before inserting more text.
|

The "insert" mark of a buffer can be obtained with <link
|

linkend="gtk-text-buffer-get-insert">gtk_text_buffer_get_insert()</link>.
|
||||
The <literal>GTK_TYPE_BLAH</literal> macros are defined as calls to
|
||||
<literal>gtk_blah_get_type()</literal>, and the <literal>_get_type()</literal> functions
|
||||
are declared as <literal>G_GNUC_CONST</literal> which allows the compiler to optimize
|
||||
the call away if it appears that the value is not being used.

To ensure that the end of the buffer remains visible, use

A common workaround for this problem is to store the result in a volatile variable,
|

which keeps the compiler from optimizing the call away.
