Widgetset

Interaction of class libraries and widgetsets in Lazarus and Free Pascal

Widgetsets support platform-sensitive development with the Lazarus IDE. They act as adapter libraries that provide an interface between a platform-inpedentent sourcecode written in Free Pascal and platform-specific system functions. Thus they allow for development of platform-native software without requiring to provide specific source code for different target platforms.

Widgetsets act as basis for the Lazarus Component Library (LCL).

Available widgetsets

Currently (autumn 2013), the development status of widget toolkit interfaces is roughly as follows:[1]
