The Line Structure

You use the gxLine structure to specify the geometry of a line shape.

The gxLine structure is defined as follows:

struct gxLine {
   struct gxPoint first;
   struct gxPoint last;
};

Field Description

first

The coordinate position where the line begins.

last

The coordinate position where the line ends.

Notice that the endpoints of a line are ordered--lines have an implicit direction. This direction can affect how QuickDraw GX draws a line shape, particularly when the line shape has stylistic variations.

For more information about lines and line shapes, see "Line Shapes" on page 2-17.
