Class DataColumn
public abstract class DataColumn
extends java.lang.Object
Represents a block in which data can be stored in a
TreeModel
(such
as
ListStore
or
TreeStore
). In Gtk, these are called columns
and are referenced by integers. We have renamed them to DataBlocks to avoid
confusion with
TreeViewColumn
s and created these objects to use
rather than integers. This allows type checking and should make programs more
maintainable. This is an abstract class - there is an implementation of it
for each type of data accepted by the two tree models.
boolean | equals(DataColumn col) - Determine if the given DataColumn represents the same column in the store
as the current object.
|
int | getColumn() - Returns the column number of this dataBlock used internally by Gtk.
|
Type | getType() - Returns the glib Type of data contained in this column.

equals
public boolean equals(DataColumn col)
Determine if the given DataColumn represents the same column in the store
as the current object. This compares the column ids using the
getColumn()
method.
getColumn
public int getColumn()
Returns the column number of this dataBlock used internally by Gtk.
getType
public Type getType()
Returns the glib Type of data contained in this column. This can only be
called once. (it is only needed once - in the constructor of the
listStore/TreeStore)
