88 /**
89  * Description
90  * The GtkCellRenderer is a base class of a set of objects used for
91  * rendering a cell to a GdkDrawable. These objects are used primarily by
92  * the GtkTreeView widget, though they aren't tied to them in any
93  * specific way. It is worth noting that GtkCellRenderer is not a
94  * GtkWidget and cannot be treated as such.
95  * The primary use of a GtkCellRenderer is for drawing a certain graphical
96  * elements on a GdkDrawable. Typically, one cell renderer is used to
97  * draw many cells on the screen. To this extent, it isn't expected that a
98  * CellRenderer keep any permanent state around. Instead, any state is set
99  * just prior to use using GObjects property system. Then, the
100  * cell is measured using gtk_cell_renderer_get_size(). Finally, the cell
101  * is rendered in the correct location using gtk_cell_renderer_render().
102  * There are a number of rules that must be followed when writing a new
103  * GtkCellRenderer. First and formost, it's important that a certain set
104  * of properties will always yield a cell renderer of the same size,
105  * barring a GtkStyle change. The GtkCellRenderer also has a number of
106  * generic properties that are expected to be honored by all children.
107  * Beyond merely rendering a cell, cell renderers can optionally
108  * provide active user interface elements. A cell renderer can be
109  * activatable like GtkCellRendererToggle,
110  * which toggles when it gets activated by a mouse click, or it can be
111  * editable like GtkCellRendererText, which
112  * allows the user to edit the text using a GtkEntry.
113  * To make a cell renderer activatable or editable, you have to
114  * implement the activate or start_editing virtual functions,
115  * respectively.
