<a name="GtkCellRendererSpin.description"></a><h2>Description</h2>
<p><a class="link" href="GtkCellRendererSpin.html" title="GtkCellRendererSpin"><span class="type">GtkCellRendererSpin</span></a> renders text in a cell like <a class="link" href="GtkCellRendererText.html" title="GtkCellRendererText"><span class="type">GtkCellRendererText</span></a> from
which it is derived. But while <a class="link" href="GtkCellRendererText.html" title="GtkCellRendererText"><span class="type">GtkCellRendererText</span></a> offers a simple entry to
edit the text, <a class="link" href="GtkCellRendererSpin.html" title="GtkCellRendererSpin"><span class="type">GtkCellRendererSpin</span></a> offers a <a class="link" href="GtkSpinButton.html" title="GtkSpinButton"><span class="type">GtkSpinButton</span></a> widget. Of course,
that means that the text has to be parseable as a floating point number.</p>
<p>The range of the spinbutton is taken from the adjustment property of the
cell renderer, which can be set explicitly or mapped to a column in the
tree model, like all properties of cell renders. <a class="link" href="GtkCellRendererSpin.html" title="GtkCellRendererSpin"><span class="type">GtkCellRendererSpin</span></a>
also has properties for the <a class="link" href="GtkCellRendererSpin.html#GtkCellRendererSpin--climb-rate" title="The “climb-rate” property"><span class="type">“climb-rate”</span></a> and the number
of <a class="link" href="GtkCellRendererSpin.html#GtkCellRendererSpin--digits" title="The “digits” property"><span class="type">“digits”</span></a> to display. Other <a class="link" href="GtkSpinButton.html" title="GtkSpinButton"><span class="type">GtkSpinButton</span></a> properties
can be set in a handler for the <a class="link" href="GtkCellRenderer.html#GtkCellRenderer-editing-started" title="The “editing-started” signal"><span class="type">“editing-started”</span></a> signal.</p>
<p>The <a class="link" href="GtkCellRendererSpin.html" title="GtkCellRendererSpin"><span class="type">GtkCellRendererSpin</span></a> cell renderer was added in GTK+ 2.10.</p>
