Detailed Description

Class to deal with PointWarpData objects.

Work with PointWarpData to define a point field for use in warping in a conformal manner.

Member Function Documentation

void LaxInterfaces::PointWarpInterface::Clear ( SomeData * d = NULL )

virtual

Delete data, and flush curpoints. Make needtodraw=1.

*** this might not be necessary, default Clear() calls deletedata() which flushes...

Implements LaxInterfaces::anInterface.

References deletedata(), and LaxInterfaces::anInterface::needtodraw.

int LaxInterfaces::PointWarpInterface::MouseMove	(	int	x,
		int	y,
		unsigned int	state,
		const Laxkit::LaxMouse *	d
	)

virtual

Todo:: revamp controls: plain click in, not on point, be like image

Reimplemented from LaxInterfaces::anInterface.

References LaxInterfaces::PointWarpData::FindBBox(), Laxkit::ButtonDownInfo::isdown(), LaxInterfaces::anInterface::needtodraw, LaxInterfaces::anInterface::screentoreal(), and Laxkit::transform_point_inverse().

PointWarpData * LaxInterfaces::PointWarpInterface::newPointWarpData	(	double	xx,
		double	yy,
		double	ww,
		double	hh,
		int	nr,
		int	nc,
		unsigned int	stle
	)

virtual

Return a new local PointWarpData.

Usually, subclasses would redefine this, which gets called from LBDown(). Returns object with count of 1.

References LaxInterfaces::PointWarpData::FindBBox().

int LaxInterfaces::PointWarpInterface::Refresh ( )

virtual

Draw in grid form. Calls drawpatch(r,c) for each subpatch. Derived classes need not redo Refresh. They can just redo drawpatch().

Todo:: *** maybe should break off drawing of various decorations to other functions, so for instance, the colorpatch can draw controls as little color bubbles, which is much more useful when in "outline" mode, if that ever gets implemented

Reimplemented from LaxInterfaces::anInterface.

int LaxInterfaces::PointWarpInterface::scan	(	int	x,
		int	y
	)

virtual

*** need better scanning, to start at point after currently selected // no pick wild,start,end, picks closest within a distance // *** only checks points, no online jazz
