OVERVIEW<\/strong><\/p>\n\n\n\n

wxGrid sets up a grid with rows and columns, much like a spreadsheet and then add text to each of the cells. That is the basic wxGrid implementation. You can subclass it to create more sophisticated tabular data display of complex objects.<\/p>\n\n\n\n

The sample code below creates a wxGrid with custom colors, content and cell formatting. The first column is read-only containing employee codes. The second column allows entry of any string for employee name. The third column only accepts float or double values for salary amount.<\/p>\n\n\n\n
