Qpfcalc

This release includes speedup of file loading code, predefined pipe sizes, minor GUI changes, and bugfixes.

This release is a rewrite of the pfc parsing code to speed up loading of pfc files. It adds a pipe labels column. Version 1.1 of the pfc file format has been created in order to store pipe labels. This release implements exporting to HTML files, and implements pipe material selection. There are some bugfixes.

The default extension for saving/opening has been changed from csv to pfc. This release stores settings for the current version, not 0.1. It prevents users from entering a "," in the table cell, which would interfere with the CSV parsing code. It implements an option for using imperial units. It adds a progress bar for sort operations longer than a second. It changes the column sizing code. Now columns resize with the window. Code clean-up. It adds code to avoid calculating or exporting an empty table and inform the user through a message box.

This release adds a table context menu, alternates background colors for table rows, implements copying to the clipboard, adds a menu item for selecting all rows, implements sorting by clicking on header labels, and updates the help system.

This release implements import/export from open document format spreadsheet files (ods files). It adds support for a new XML-based file format: pipe friction calculation (pfc). It implements water as a default built-in fluid. Instead of passing "default" to pfcalc, a temporary file containing water definition is passed. It adds a way for users to associate a description with a calculation. More icons have been added to the toolbar. Print support has been added. Help has been updated. Code has been rewritten.
