	Called after the parent viewport gets resized.
virtual void	Mapped ()
	Called after the parent viewport gets mapped (made visible).
virtual void	Unmapped ()
	Called after the parent viewport gets mapped (made invisible, such as offscreen, not merely obscured).

virtual int	UseThisObject (ObjectContext *oc)
virtual int	DrawData (Laxkit::anObject *ndata, Laxkit::anObject *a1=NULL, Laxkit::anObject *a2=NULL, int info=0)
	Redefine this for interfaces that can draw data not owned, without loosing current data.
virtual Laxkit::anXWindow *	CurrentWindow (Laxkit::anXWindow *ncur)
	Set the window the interface works on to ncur. Returns ncur. If ncur==NULL, then just return current viewport.

virtual double	GetVMag (int x, int y)
	Do a little extra checking to find what the magnification is.
virtual void	dump_out (FILE *f, int indent, int what, Laxkit::anObject *savecontext)
	Default settings saving is to output nothing.
virtual void	dump_in_atts (LaxFiles::Attribute *att, int flag, Laxkit::anObject *loadcontext)
	Placeholder for dumping in settings.
Public Member Functions inherited from LaxFiles::DumpUtility
virtual Attribute *	dump_out_atts (Attribute *att, int what, Laxkit::anObject *savecontext)
	Default is return NULL. what==0 means write out normal Attribute formatted things.
virtual void	dump_in (FILE *f, int indent, int what, Laxkit::anObject *loadcontext, Attribute **att)
	Read in a file segment as an Attribute, and pass parsing duties to dump_in_atts.
virtual	~DumpUtility ()
	Empty virtual destructor.

Detailed Description

Interface for LinesData, just straight point to point lines.

Todo:

this is really old code and needs a good going over

Member Function Documentation

int LaxInterfaces::LinesInterface::CharInput ( unsigned int  ch, const char *  buffer, int  len, unsigned int  state  )

virtual

  del/bksp  delete a point
  '?'       post help message
  ' '       make a creating rectangle square with real
  'c'       toggle a closed path
  'd'       toggle decorations
  'm'       change mode between lines, polygon, and symmetric polygon
  'r'       make rectangles
  'b'       begin new one
 

int LaxInterfaces::LinesInterface::UseThis ( Laxkit::anObject *  newdata, unsigned int  mask = 0  )

virtual

Todo:

does viewport->NewData(newdata).. maybe newdata exists in it already?

Reimplemented from LaxInterfaces::anInterface.
