 189 <p>
 190 The <a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a> is a base class of a set of objects used for
 191 rendering a cell to a <a href="/usr/share/gtk-doc/html/cairo/cairo-cairo-t.html#cairo-t"><span class="type">cairo_t</span></a>.  These objects are used primarily by
 192 the <a class="link" href="GtkTreeView.html" title="GtkTreeView"><span class="type">GtkTreeView</span></a> widget, though they aren't tied to them in any
 193 specific way.  It is worth noting that <a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a> is not a
 194 <a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a> and cannot be treated as such.
 195 </p>
 196 <p>
 197 The primary use of a <a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a> is for drawing a certain graphical
 198 elements on a <a href="/usr/share/gtk-doc/html/cairo/cairo-cairo-t.html#cairo-t"><span class="type">cairo_t</span></a>. Typically, one cell renderer is used to
 199 draw many cells on the screen.  To this extent, it isn't expected that a
 200 CellRenderer keep any permanent state around.  Instead, any state is set
 201 just prior to use using <a href="http://library.gnome.org/devel/gobject/unstable/gobject-The-Base-Object-Type.html#GObject"><span class="type">GObject</span></a>s property system.  Then, the
 202 cell is measured using <a class="link" href="GtkCellRenderer.html#gtk-cell-renderer-get-size" title="gtk_cell_renderer_get_size ()"><code class="function">gtk_cell_renderer_get_size()</code></a>. Finally, the cell
 203 is rendered in the correct location using <a class="link" href="GtkCellRenderer.html#gtk-cell-renderer-render" title="gtk_cell_renderer_render ()"><code class="function">gtk_cell_renderer_render()</code></a>.
 204 </p>
 205 <p>
 206 There are a number of rules that must be followed when writing a new
 207 <a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a>.  First and formost, its important that a certain set
 208 of properties will always yield a cell renderer of the same size,
 209 barring a <a class="link" href="GtkStyle.html" title="GtkStyle"><span class="type">GtkStyle</span></a> change.  The <a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a> also has a number of
 210 generic properties that are expected to be honored by all children.
 211 </p>
 212 <p>
 213 Beyond merely rendering a cell, cell renderers can optionally
 214 provide active user interface elements. A cell renderer can be
 215 <em class="firstterm">activatable</em> like <a class="link" href="GtkCellRendererToggle.html" title="GtkCellRendererToggle"><span class="type">GtkCellRendererToggle</span></a>,
 216 which toggles when it gets activated by a mouse click, or it can be
 217 <em class="firstterm">editable</em> like <a class="link" href="GtkCellRendererText.html" title="GtkCellRendererText"><span class="type">GtkCellRendererText</span></a>, which
 218 allows the user to edit the text using a <a class="link" href="GtkEntry.html" title="GtkEntry"><span class="type">GtkEntry</span></a>.
 219 To make a cell renderer activatable or editable, you have to
 220 implement the <span class="type">GtkCellRendererClass.activate</span> or
 221 <span class="type">GtkCellRendererClass.start_editing</span> virtual functions, respectively.

1420 This signal gets emitted when a cell starts to be edited.
1421 The intended use of this signal is to do special setup
1422 on <em class="parameter"><code>editable</code></em>, e.g. adding a <a class="link" href="GtkEntryCompletion.html" title="GtkEntryCompletion"><span class="type">GtkEntryCompletion</span></a> or setting
1423 up additional columns in a <a class="link" href="GtkComboBox.html" title="GtkComboBox"><span class="type">GtkComboBox</span></a>.
1424 </p>
1425 <p>
1426 Note that GTK+ doesn't guarantee that cell renderers will
1427 continue to use the same kind of widget for editing in future
1428 releases, therefore you should check the type of <em class="parameter"><code>editable</code></em>
1429 before doing any specific setup, as in the following example:
