44<center><h2>TGTable</h2></center>
45<br><br>
46TGTable implements a table widget to display data in rows and
47columns. The data is supplied by a TVirtualTableInterface.
48<br><br>
49The table is a TGCanvas to make use of already available viewport
50functionality and drawing optimizations.
51<br><br>
52The top left cell in a table has coordinates (0,0)
53<br><br>
54A TObjArray is used internally to ensure little overhead and fast
55acces to cells.
56<br><br>
57If the data source has more rows than the default 50 rows of cells in
58memory, buttons at the bottom of the table can be used to load the
59next or previous chunk of data.
60<br><br>
61At the top of the table, a frame is visible that shows the coordinates
62of the top left cell currently in memmory in row,column. The amount of
63rows and columns is also shown in rows x columns. These values can be
64edited to move to a different area of the data source or to resize the
65table. Tab will switch between the enties, return will move to the
66currently entered range and resize the table if needed. Clicking the
67goto button has the same effect.
68<br><br>
69A TGTable is created by first creating an appropriate
70TVirtualTableInterface from the data that needs visualization and
71then creating the TGTable using this interface.
72<br><br>
73A simple macro to use a TGTable with a TGSimpleTableInterface:

81 data[i] = new Double_t[ncolumns];
82 for (j = 0; j < ncolumns; j++) {
83 data[i][j] = 10 * i + j;
84 }
85 }

87 // Create a main frame to contain the table
88 TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
89 mainframe->SetCleanup(kDeepCleanup) ;
