"Widget Set" is the more common term, but in Lazarus it's (mostly, e.g. 
Project -> Options -> Compiler Options) "Widget Type".

While a "Widget Set" usually is a collection of layout (and 
functionality) instructions for commonly used GUI control elements, in 
Lazarus it is more than this, definig a large part of the OS API a 
project is supposed to use, and even is important for projects that 
don't use a GUI at all. E.g. the function of TTimer and inter Thread 
Messaging is defined in the code for the Widget Set used with the 
project. Unfortunately this results in some widgets sets that don't 
allow for using TTimer and inter Thread Messaging.
