bezier_curve ->control1: point

1st Control-point of the Bezier curve.

bezier_curve ->control2: point*

Inherits description from: bezier_curve-control1, bezier_curve->control1

bezier_curve ->geometry: x=[int], y=[int], width=[int], height=[int]

The graphical->geometry method is redefined by class bezier to move the bezier curve.

bezier_curve ->initialise: start=point, end=point, control1=point, control2=[point]*

Create a bezier_curve object starting at start going to end using either one (quadratic) or two (cubic) control-points.

bezier_curve ->selected: bool

Refines graphical->selected to deal with the graphical<-area change resulting from displaying the control-points.

The control-points and dotted connection-lines are visible if the window<-selection_feedback is set to handles.

bezier_curve ->set_point: point=point, x=[int], y=[int]

Move (member) point to (X, Y). Depending on the point, this modifies bezier_curve<-start, bezier_curve<-control1, bezier_curve<-control2 or bezier_curve<-end and bezier_curve->compute’s the curve afterwards,

It is normally used with the result if bezier_curve<-point to allow interactive editing of bezier curves. See also the PceDraw demo application.
