Sourced from http://torry.net/pages.php?id=144#939779 - TListViewEx v1.0.

Added facility to sort any column of the warnings list view by clicking the column heading.

Added "Restore Defaults" button and action that restores warnings list to default state.

Added TWarnings.Defaults class method that creates a TWarnings object containing a list of default warnings.

* Replaced standard list item class with new TWarningListItem that has a property to store warning and modified existing code to use it.
* Revised code that creates and modifies a list item.
* Rationalised code that sets controls used to modify a warning to use TCodeGenPrefsFrame.UpdateControls method.
* Cleared both radio buttons when no warning is selected.

* Added support for new warning state: new radio buttons to select state, new column in list view to display state.
* Changed list view code to store reference to associated warning with each list item.

Removed TWarning constructor that took only a symbol name as parameter and modified code that called it (in only a single place in same unit) to use full form of constructor, passing dummy min. compiler and state values.

* Modified to permit a warning to be switched on as well as off, with state being set by new TWarning.State parameter.
* Made changes to TWarningsPersist and TWarnings.Render to support new warning state.
* Changed IWarnings.Delete method, and implementation, to take a TWarning parameter instead of symbol name string parameter.

Renamed TWarnings.SwitchOff property as Enabled.
Modified all using code.
Also changed name of check box that updates this property in TCodeGenPrefsFrame to suit.

NOTE: Name of item relating to TWarnings.Enabled in User.config remains "SwitchOffWarnings" for backward compatibility reasons.

Replaced American English word "dialog" with English "dialogue" in affected file format documentation file.
