Please if you are interested in opie-sheet try it hard, so I can fix some of them. Also If you want some other functions that must be here and are missing feel free to ask them. (no financial functions please. :) I really hate them ) -Fixed a bug with non closed parenthesis editing&recalculation infinite loop. -Added support for functions that can parse parameters not ONLY as numbers but also as strings. -Added many functions that cover many computational topics rendering opie-sheet a computational tool-spreadsheet at last. (total 90 functions!) -Maintained compatibility with the opie-fileformat. -New icons. - -Found that the DataParser was not a real RPN compiler of the expressions. In fact it was returning faulty results in calculations, in both binary or unary operations. A1-A2-A3 was parsed as A1-(A2-A3). A1 was parsed as A1. + -Found that the DataParser was not a real RPN compiler of the expressions. In fact it was returning faulty results in calculations, in both binary or unary operations. A1-A2-A3 was parsed as A1-(A2-A3). -A1 was parsed as A1. -Added new class "Expression" a general Parser for spreadsheet-expression. Imported from an old C# project of mine. -Now can also parse <>=!%&^|"" in expressions. -Added experimental Excel File format import!. The opie-sheet can import any excel file in BIFF7/BIFF8 format. These formats are used in Excel XP,2000,95. The Excel Importer class is in a good coding level.. BUT it is not complete. Only strings,numbers,formulas are imported. Not formatting rules. Not all the functions are converted in the functions of opie-sheet. Infact FEW functions are converted. -Fixed a bug with Sheet Recalculation. Added ReCalc() function. Opie-sheet was calculating wrong the values of expression in opening/importing. if a value needed was not loaded yet in the time of calculation. Solved with ReCalc() each time the active sheet is changing. *known issues: -if someone enters directly text as parameter to a string function the text renders as uppercase due to the calculation engine that uppercases all the parsing sentence. -randbetween return only integer part random... if both limit numbers are integers. -skew and kurt function give different results compared to kspread-oofice equivalents. -unstable parser Excel Class -string vars and string functions are not correctly handled by excel importer. -unicode strings are converted FINE in QString unicode format, but cannot be rendered fine if a suitable unicode font is not setuped as the default string. So the string is junked in the opie-sheet and may crash the parser. *TODOs: -surelly a much full-stable excel importer. -Cell Manipulation of many Data is really slow.... must change the QList data type. To a structure more efficient. -maybe some more functions. -maybe some kind of charts drawing? -maybe kspread or ooffice files import/export. October 08, 2002 * Release 1.0.2 (by thufir) - Fixed bug #250 (exhibiting re-calculation error in multi-level calculation). (by thufir) October 06, 2002 - Fixed data edit box clear problem. (by thufir) October 05, 2002 - Fixed bug #252 (starting up in 'mouse button' mode). (by thufir) August 31, 2002 - Fixed and updated opie-sheet.pro file. (by cniehaus) August 01, 2002 - Fixed gcc3 compile problems. (by harlekin) July 06, 2002 - Fixed DocLnk management to save documents correctly. (by leseb) July 04, 2002 |
