I've just noticed a newsgroup posting by the CodeGear VP of Products & Strategy, Michael Swindell.
The VCL for PHP documentation is live!
I hope this is the way our documentation will go in the future.
To quote Michael, 'This new version is done more in the "Delphi way" and now includes all the published properties, methods, and events for each component class, not just the underlying getters and setters behind them.'
This is all very exciting for me...
In 2017, with the release of Delphi 10.2 Tokyo, Embarcadero introduced a specialized implementation of the Observer pattern into the System.Classes unit. While it has been in the wild for 9 years, it remains a "hidden" architecture for many, primarily because it serves as the invisible engine behind LiveBindings. Other than live bindings, you can also use the Observer pattern as a way to update component settings to the Windows registry, an .ini file, or persist it elsewhere.
