void Laxkit::ColorSliders::SetBar ( int  whichbar,
double  pos 
)
virtual

pos is clamped to [0..1].

References Laxkit::PtrStack< T >::e, and Laxkit::PtrStack< T >::n.

void Laxkit::ColorSliders::updateSliderRect ( )
virtual

Respond to window resizes by updating where sliders, hex and old new are drawn in.
