3 /// This TableTest class is a simple example of how to use a TGSimpleTable that creates and owns it's own TGSimpleTableInterface.
4 /// TableTest inherits from TGMainFrame to create a top level frame to embed the TGTable in.
5 /// First the data needed is created. Then the TGSimpleTable is created using this data.
6 /// In the end, the table is added to the TGMainFrame that is the TableTest and the necessary calls to correctly draw the window are made.
7 /// For more information about the use of TGSimpleTable see it's documentation.
