SimpleTableView example Example use of DBTableView This application is provided in source form only, compilable on any NEXTSTEP 3.1 system (68k, or 486). It may also compile fine on 3.0 versions of NEXTSTEP, but it has not been tested on that platform. This application doesn't necessarily provide any useful functionality by itself. But it does provide an example using the DBTableView object within the dbkit. It shows how to supply custom DBFormatter subclasses for DBTableView for displaying data in table form. After compiling the example code, select the "open" function from the "Table" submenu. Select and open the file named "sample.simpleTbl" within the app wrapper. This text file contains a simple table format used by SimpleTableView.app. Rows can be added, and deleted. Items in the table can be changed. And the column widths can be changed with the mouse by dragging on the edges of the column titles. Table data and column widths are saved back to the file when "Save" is selected. Columns can also be moved from one location to another, but column location is not currently saved to the text file. In this example, the first column of the table is considered the key column in the table. All entries in the first column must be unique. --------------------------------------------------------------------------------------------------------------------- You may redistribute this example program and source code, and to use fragments of this code in your own applications if you find them to be useful.
