z_sliders

points of the complex plane which can be picked and moved

f zSlider() ...

factory' function returns instance of a class representing a point of the complex plane which can be picked and moved

constructors:
zSlider (zline <,ratio = float> )
complex point on the given complex line which can be picked, with movement constrained to the given line and with initial position determined by the 'ratio' keyword.
zSlider (zcircle <,angle = float> )
complex point on the given complex circle which can be picked, with movement constrained to the given circle and with initial position determined by the 'angle' keyword.
zSlider (float <,float> )
complex point intially at given (real,imaginary) coordinates that can be picked and moved freely on the complex plane
