Spreadsheet with Xbrowse

[Silvio.Falconi]

I 'd like to re- create a small Spreadsheet with xbrowse

Many year ago on Dos I had a small SpreadSheet of Nantucket Corporation (1991 Clipper 5.01 - Release 1.29 )

I have the source code of it but the dos release used TBrowse class

the dialog had two folders

on First there is the SpreadSheet with numbers and test

on second you can see the formulas style lotus sample A3 / 3) + (A5 * 21.2) - 4 it supported operators: ( ) + - * /


but it had only six columns but I think with xbrowse we can have infinite columns






someone can help me to recreate it on xbrowse ?

Another test


I made an array 10x10 to try but I think it can be infinite but I not Know how make it

I 'm making a class Tlotus ... some can help me ?

I had thought about creating an array {100, 1000}, but hide columns that are not visible or are empty (and no subsequent rows or columns with data)
Then gradually add rows or columns if needed

yes I tried 1000x1000 but the exe is too slow to open
