The is a base class of a set of objects used for rendering a cell to a .
These objects are used primarily by the widget, though they are not tied to them in any specific way.
It is worth noting that is not a and cannot be treated as such.
The primary use of a is for drawing a certain graphical elements on a .
Typically, one is used to draw many cells on the screen.
To this extent, it is not expected that a keep any permanent state around.
Instead, any state is set just prior to use.
Then, the cell is measured using .
Finally, the cell is rendered in the correct location using .
There are a number of rules that must be followed when writing a new .
First and foremost, it is important that a certain set of properties will always yield a of the same size, barring a change.
The also has a number of generic properties that are expected to be honored by all children.

This event is raised when the user cancels the process of
editing a cell.
For example, an editable cell renderer could be written to cancel
editing when the user presses Escape.
EventGLib.Signal("editing-started")Gtk.EditingStartedHandlerThis signal gets emitted when a cell starts to be edited.
The intended use of this signal is to do special setup on editable cell, e.g. adding a or setting up additional columns in a .
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 the cell before doing any specifi setup.
