Class CellRenderer

public class CellRenderer extends GtkObject

Deprecated: This class is part of the java-gnome 2.x family of libraries, which, due to their inefficiency and complexity, are no longer being maintained and have been abandoned by the java-gnome project. This class may in the future have an equivalent in java-gnome 4.0, try looking for org.gnome.gtk.CellRenderer. You should be aware that there is a considerably different API in the new library: the architecture is completely different and most notably internals are no longer exposed to public view.

A CellRenderer is an object used to render data in a TreeView widget. This is for all types of Table, Tree and list. Each renderer has one or more CellRendererAttribute. These attributes are for data to be rendered. This data is usually stored in a TreeModel object; the two current implementations of TreeModel being ListStore (for tables and lists) and TreeStore for trees.

The choice of data to be rendered is particular to the TreeView widget - any number of TreeView widgets may share the same data and choose to display only a selection of it. Data is displayed in a TreeView widget by attaching TreeViewColumns and packing any number of CellRenderers into each column. Links are then made between the renderers and the data in the model via the TreeViewColumn method.

This class is a base class for the renderers, either home grown or any of the following standard renderers:

For a full overview of the tree and list objects, see the TreeView description.

Method Detail

getType

public static Type getType()

Deprecated: Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
