TableViewExample
by Mai Nguyen, NeXT Developer Support Team

Overview

In order to run this example, you need to have an ORACLE server with a demo database installed.  You should install the OracleDemo.dbmodel from /NextDeveloper/Examples/DatabaseKit/Models into your ~/Library/Databases directory.
This example shows how you can define a DBTableView and a DBModule programmatically instead of using the corresponding Interface Builder UI Objects .


Program Organization

Major Classes in the Application

 
TableViewController	A general manager object.  A subclass of the Object class.  Performs miscellaneous 		initialzations for the DBModule and DBTableView objects. 


Other Peculiarities
In order to load an Adaptor dynamically, you need to add the OTHER_LDFLAGS definition (see the Makefile.preamble). You also need to add the libdbkit_s.a library into your PB.project under libraries in order to use the DBKit API. 
Note that you will get a compiler warning: method 'getProperties' not implemented by protocol that you can ignore. This method was needed to retrieve attributes from a one-to-one relationship.
