classdef GtGuiJoinableElem < GtBaseGuiElem
% Class GtGuiJoinableElem: base class for joinable graphical user interfaces. It
% is useful in case you want to build a GUI object that should return a value.
%
% It makes the object oriented GUI implementations equivalent to function
% implementations.
%
% Working with it is simple: you first instanciate your object, and then you
% expect a result from the call to the join() method.

% >> objHandle = DerivedClass(blabla);
% >> expectedResult = objHandle.join();
