int Laxkit::ColorSliders::GetPos	(	int	x,
		int	y,
		double *	pos,
		int *	half
	)

virtual

Screen coordinates x,y. half is 1 for upper half (absolute placement) or 0 for lower (for panning).

Return -1 for not on anything. Return -2 for hex, -3 for old, or -4 for new.

double Laxkit::ColorSliders::GetPosForBar ( int whichbar )

virtual

Return what the bar->pos should be, not what it actually contains.

Returns -1 for no such bar.

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

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.

Meaning, change the IntRectangles sliders, hex, and oldnew.
