  * gtk_tree_view_column_set_fixed_width:
  * @tree_column: A #GtkTreeViewColumn.
- * @fixed_width: The size to set @tree_column to. Must be greater than 0.
- * 
- * Sets the size of the column in pixels.  This is meaningful only if the sizing
- * type is #GTK_TREE_VIEW_COLUMN_FIXED.  The size of the column is clamped to
- * the min/max width for the column.  Please note that the min/max width of the
- * column doesn't actually affect the "fixed_width" property of the widget, just
- * the actual size when displayed.
+ * @fixed_width: The new fixed width, in pixels, or -1.
+ *
+ * If @fixed_width is not -1, sets the fixed width of @tree_column; otherwise
+ * unsets it.  The effective value of @fixed_width is clamped between the
+ * minumum and maximum width of the column; however, the value stored in the
+ * "fixed-width" property is not clamped.  If the column sizing is 
+ * #GTK_TREE_VIEW_COLUMN_GROW_ONLY or #GTK_TREE_VIEW_COLUMN_AUTOSIZE, setting a
+ * fixed width overrides the automatically calculated width.  Note that
+ * @fixed_width is only a hint to GTK+; the width actually allocated to the
+ * column may be greater or less than requested.
+ *
+ * Along with "expand", the "fixed-width" property changes when the column is
+ * resized by the user.
