NAME
XmeDrawArrow - Draws a Motif-style, three-dimensional arrow
SYNOPSIS
#include <Xm/DrawP.h>
void XmeDrawArrow(
Display *display,
Drawable drawable,
GC top_gc,
GC bottom_gc,
GC center_gc,
Position x,
Position y,
Dimension width,
Dimension height,
Dimension shadow_thickness,
unsigned char direction);
VERSION
This page documents Motif 2.1.
DESCRIPTION
XmeDrawArrow draws a Motif-style arrowhead surrounded by
Motif-style shadows. The routine always draws the arrowhead
as an equilateral triangle.
This function does not draw the tail of the arrow.
Furthermore, this function does not allow you to draw a
broad range of arrow shapes (for example, you cannot draw a
curved arrow). You can, however, control the direction that
the arrowhead faces.
Four of the arguments to XmeDrawArrow (x, y, width, and
height) describe a bounding box. The bounding box encloses
not only the arrowhead but its shadows as well. XmeDrawArrow
centers the arrowhead within the bounding box.
display Specifies the display on which the arrow is to be
rendered.
drawable Specifies the drawable in which the arrow is to be
rendered. (Typically, this drawable is a widget
window.)
top_gc Specifies the graphics context of the shadow that
is generally above and to the left of the
triangular arrowhead.
bottom_gc Specifies the graphics context of the shadow that
is generally below and to the right of the
triangular arrowhead.

center_gc Specifies the graphics context of the arrow
itself.
If center_gc is NULL, the diamond will not be
filled, but the shadow will still be drawn.
x Specifies the leftmost point of the bounding box.
y Specifies the top of the bounding box.
width Specifies the width of the bounding box.
height Specifies the height of the bounding box.
shadow_thickness
Specifies the thickness of the arrow's shadows in
pixels. At Motif Release 2.0, the only supported
values of shadow_thicknessare 0 (no shadow), 1, or
2.
direction Specifies the direction of the arrow. The
direction must be one of the following values:
XmARROW_RIGHT, XmARROW_LEFT, XmARROW_UP, or
XmARROW_DOWN.
