<p>
Finds the path at the point (<em class="parameter"><code>x</code></em>, <em class="parameter"><code>y</code></em>), relative to bin_window coordinates.
In contrast to <a class="link" href="GtkIconView.html#gtk-icon-view-get-path-at-pos"><code class="function">gtk_icon_view_get_path_at_pos()</code></a>, this function also 
obtains the cell at the specified position. The returned path should
be freed with <a class="link" href="GtkTreeModel.html#gtk-tree-path-free"><code class="function">gtk_tree_path_free()</code></a>.
See <a class="link" href="GtkIconView.html#gtk-icon-view-convert-widget-to-bin-window-coords"><code class="function">gtk_icon_view_convert_widget_to_bin_window_coords()</code></a> for converting
widget coordinates to bin_window coordinates.</p>

Sets the current keyboard focus to be at <em class="parameter"><code>path</code></em>, and selects it.  This is
useful when you want to focus the user's attention on a particular item.  
If <em class="parameter"><code>cell</code></em> is not <a
href="/usr/share/gtk-doc/html/liboil/liboil-liboiljunk.html#NULL:CAPS"
><code class="literal">NULL</code></a>, then focus is given to the cell specified by 
it. Additionally, if <em class="parameter"><code>start_editing</code></em> is <a
href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#TRUE:CAPS"
><code class="literal">TRUE</code></a>, then editing should be 
started in the specified cell.  
</p>
<p>
This function is often followed by <code class="literal">gtk_widget_grab_focus 
(icon_view)</code> in order to give keyboard focus to the widget.  
Please note that editing can only happen when the widget is realized.</p>
