<hr><a name="_details"></a><h2>Detailed Description</h2>
A GtkCellRenderer C++ wrapper class.
<p>
The purpose of the cell renderers is to provide extensibility to the widget and to allow multiple ways of rendering the same type of data. For example, consider how to render a bool variable. Should you render it as a string of "true" or "false", "On" or "Off", or should you render it as a checkbox?<p>
The <a class="el" href="classGFC_1_1Gtk_1_1TreeView.html">TreeView</a> widget uses columns and cell renderers to display a model. Cell renderers are used to draw the data in the tree model in a certain way. There are three cell renderers that come with <a class="elRef" doxygen="gfccore.tag:" href="namespaceGFC.html">GFC</a>. They are the <a class="el" href="classGFC_1_1Gtk_1_1CellRendererText.html">CellRendererText</a>, <a class="el" href="classGFC_1_1Gtk_1_1CellRendererPixbuf.html">CellRendererPixbuf</a> and <a class="el" href="classGFC_1_1Gtk_1_1CellRendererToggle.html">CellRendererToggle</a>. It is relatively easy to write a custom renderer.
