Fire Monkey is a vector-based WPF-like framework for UIs on Windows, OSX, i OS and Android.

The Lazarus project has a portable (*nix, OS/X, Win32/64 wince) equivalent called LCL, which was already working when Kylix and CLX emerged.

The project maintained its course and ignored Kylix (and later FMX) Open and thus Libre Office contains an unrelated graphic library also called Visual Components Library (VCL).

Destroy; begin Free And Nil(FButton); inherited; end; procedure TButton Wrapper.

This also allowed new components - new visual or non-visual classes - to be written easily.

(For context, the Delphi variant of Pascal had a number of innovative object-oriented features, such as properties and runtime type information, inspired by Modula and Smalltalk.) At the time, much UI code work required creating classes inheriting from other classes, and customized objects were often not reusable (for example, a button that performs a specific action cannot be reused in a different application.) Finally, a visual user interface arguably should be designed visually, and yet most tools to do so - at the time, mainly Visual Basic - did so in terms of the designer outputting code, creating a fragile, un-manually-editable situation - a problem that still persists today with many UI frameworks, particularly C -based ones such as Qt.While not all VCL components are thread-safe, VCL supports multi-threading too.
