Table Widget Data Types

Table Widget Data Types

Table data can be of any IDL data type or types.

Single Data Type


If all of the table data is of the same data type, the table value is specified as a two-dimensional array.

Values returned by the GET_VALUE keyword to WIDGET_CONTROL are either a two-dimensional array (for full tables or selections when the table is in standard selection mode) or a one-dimensional array (for tables in disjoint selection mode). (See Table Widget Data Retrieval for details.)

Multiple Data Types


If the table contains data of several data types, the table value is specified as a vector of structures. All of the structures must be of the same type, and must contain one field for each row (if the COLUMN_MAJOR keyword to WIDGET_TABLE is set) or column (if the ROW_MAJOR keyword to WIDGET_TABLE is set; this is the default) in the table.

Values returned by the GET_VALUE keyword to WIDGET_CONTROL are either a vector of structures (for full tables or selections when the table is in standard selection mode) or a single structure with one field per cell (for selections when the table is in disjoint selection mode). (See Table Widget Data Retrieval for details.)
