CoordinateSystem Class Reference
#include <coordinate_system.h>
Detailed Description
a CoordinateSystem is what the user sees: it is kept by KigPart to show the user a grid, and to show the coordinates of points... it allows for weird CoordinateSystem's like homogeneous or projective... internally, it does nothing, it could almost have been an ordinary Object..., mapping coordinates from and to the screen to and from the internal coordinates is done elsewhere ( KigPainter and KigWidget... )

| virtual QString CoordinateSystem::coordinateFormatNotice | ( | ) | const [pure virtual] |
This returns a notice to say in which format coordinates should be entered.
This should be something like: i18n( "Enter coordinates in the following form: \"(x,y)\", where x is the x coordinate, and y is the y coordinate." );
Implemented in EuclideanCoords, and PolarCoords.
| virtual QString CoordinateSystem::coordinateFormatNoticeMarkup | ( | ) | const [pure virtual] |
Like coordinateFormatNotice(), but with HTML tags useful to have a rich text.
..
Implemented in EuclideanCoords, and PolarCoords.
