<p>
The <a class="link" href="GtkSourceGutter.html" title="GtkSourceGutter"><span class="type">GtkSourceGutter</span></a> object represents the left and right gutters of the text
view. It is used by <a class="link" href="GtkSourceView.html" title="GtkSourceView"><span class="type">GtkSourceView</span></a> to draw the line numbers and category
marks that might be present on a line. By packing additional <a href="http://library.gnome.org/devel/gtk/unstable/GtkCellRenderer.html"><span class="type">GtkCellRenderer</span></a>
objects in the gutter, you can extend the gutter with your own custom
drawings.
</p>
<p>
The gutter works very much the same way as cells rendered in a <a href="http://library.gnome.org/devel/gtk/unstable/GtkTreeView.html"><span class="type">GtkTreeView</span></a>.
The concept is similar, with the exception that the gutter does not have an
underlying <a href="http://library.gnome.org/devel/gtk/unstable/GtkTreeModel.html"><span class="type">GtkTreeModel</span></a>. Instead, you should use
<a class="link" href="GtkSourceGutter.html#gtk-source-gutter-set-cell-data-func" title="gtk_source_gutter_set_cell_data_func ()"><span class="type">gtk_source_gutter_set_cell_data_func</span></a> to set a callback to fill in any of the
cell renderers properties, given the line for which the cell is to be
rendered. Renderers are inserted into the gutter at a certain position. The
builtin line number renderer is at position

<p>
<a class="link" href="GtkSourceView.html#GTK-SOURCE-VIEW-GUTTER-POSITION-LINES:CAPS"><span class="type">GTK_SOURCE_VIEW_GUTTER_POSITION_LINES</span></a> (-30) and the marks renderer is at
<a class="link" href="GtkSourceView.html#GTK-SOURCE-VIEW-GUTTER-POSITION-MARKS:CAPS"><span class="type">GTK_SOURCE_VIEW_GUTTER_POSITION_MARKS</span></a> (-20). You can use these values to
position custom renderers accordingly. The width of a cell renderer can be
specified as either fixed (using

<p>
<a href="http://library.gnome.org/devel/gtk/unstable/GtkCellRenderer.html#gtk-cell-renderer-set-fixed-size"><span class="type">gtk_cell_renderer_set_fixed_size</span></a>) or dynamic, in which case you

callback is used to set the properties of the renderer such that
<a href="http://library.gnome.org/devel/gtk/unstable/GtkCellRenderer.html#gtk-cell-renderer-get-size"><span class="type">gtk_cell_renderer_get_size</span></a> yields the maximum width of the cell.
