<a name="GtkCellRenderer.description"></a><h2>Description</h2>
<p>
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
rendering a cell to a <a href="../html/gdk2-Drawing-Primitives.html#GdkDrawable-struct"><span class="type">GdkDrawable</span></a>. These objects are used primarily by
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
specific way. It is worth noting that <a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a> is not a
<a class="link" href="GtkWidget.html" title="GtkWidget"><span class="type">GtkWidget</span></a> and cannot be treated as such.
</p>
<p>
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
elements on a <a href="../html/gdk2-Drawing-Primitives.html#GdkDrawable-struct"><span class="type">GdkDrawable</span></a>. Typically, one cell renderer is used to
draw many cells on the screen. To this extent, it isn't expected that a
CellRenderer keep any permanent state around. Instead, any state is set
just prior to use using <a href="/home/vagrant/ruby-gnome2.win64/glib2/vendor/local/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#GObject-struct"><span class="type">GObject</span></a>s property system. Then, the
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
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>.
</p>
<p>
There are a number of rules that must be followed when writing a new
<a class="link" href="GtkCellRenderer.html" title="GtkCellRenderer"><span class="type">GtkCellRenderer</span></a>. First and formost, it's important that a certain set
of properties will always yield a cell renderer of the same size,
barring a <a class="link" href="GtkStyle.html" title="Styles"><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
generic properties that are expected to be honored by all children.
</p>
<p>
Beyond merely rendering a cell, cell renderers can optionally
provide active user interface elements. A cell renderer can be
<em class="firstterm">activatable</em> like <a class="link" href="GtkCellRendererToggle.html" title="GtkCellRendererToggle"><span class="type">GtkCellRendererToggle</span></a>,
which toggles when it gets activated by a mouse click, or it can be
<em class="firstterm">editable</em> like <a class="link" href="GtkCellRendererText.html" title="GtkCellRendererText"><span class="type">GtkCellRendererText</span></a>, which
allows the user to edit the text using a <a class="link" href="GtkEntry.html" title="GtkEntry"><span class="type">GtkEntry</span></a>.
To make a cell renderer activatable or editable, you have to
implement the <em class="parameter"><code>activate</code></em> or <em class="parameter"><code>start_editing</code></em> virtual functions,
respectively.

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