Description:

The PtBezier class draws a Bézier curve via PgDrawBezier().


PtBezier


A Bézier curve created by PtBezier.

The Pt_ARG_POINTS resource specifies the points in the Bézier curve. These points are relative to the widget's Pt_ARG_ORIGIN. For more information, see PtGraphic.

New resources:

Resource C type Pt type Default
Pt_ARG_BEZIER_FLAGS unsigned short Flag 0

Pt_ARG_BEZIER_FLAGS

C type Pt type Default
unsigned short Flag 0

Flags that affect the appearance of the curve; any combination of:

Pg_CLOSED
Connect the last point to the first.
Pg_RELATIVE
Use relative coordinates to draw the curve. Each point is relative to the previous point.

Inherited resources:

If the widget modifies an inherited resource, the "Default override" column indicates the new value. This modification affects any subclasses of the widget.
