You mean two versions with the same soname?
Well, that's the same old problem. But Xaw 7.0 has a solution:
DISPLAY LISTS
All the Xaw widgets have now the additional resource dis-
playList. This resource allows drawing the widget decora-
tions with commands embedded in the resource string. The
displayList resource has the syntax:
[class-name:]function-name arguments[[{;\n}]...]
Class-name is any registered set of functions to draw in
the widget. Currently the only existing class is xlib.
Function-name is the drawing or configuration function to
be called, described bellow.
Arguments may be anything suitable to the displayList
function being called. When the function requires a coor-
dinate, the syntax is {+-}<integer> or <integer>/<inte-
ger>. Examples:
+0,+0 top, left
-0,-0 bottom, right
-+10,-+10 bottom+10, right+10
+0,1/2 left, vertical-center
arc-mode mode
Sets the arc mode. Accepted parameters are "pies-
lice" and "chord", that sets the arc to ArcPieS-
lice or ArcChord, respectively. Example:
arc-mode chord
bg color-spec
background color-spec
Sets the background color. Argument must as
valid color specification. Example:
background red
cap-style style
Sets the cap style. Accepted parameters are "not-
last", "butt", "round", and "projecting", that
sets the cap style to CapNotLast, CapBut,
CapRound or CapProjecting, respectively. Example:
cap-style round
clip-mask pixmap-spec
Sets the pixmap for the clip mask. Requires a
pixmap parameter, as described in the PIXMAPS sec-
tion of this man page. Example:
clip-mask xlogo11
clip-origin x,y
Sets the clip x and y origin. Requires two argu-
ments, a x and y coordinate. Example:
clip-origin 10,10
clip-rects x1,y1,x2,y2 [...,xn,yn]
clip-rectangles x1,y1,x2,y2 [...,xn,yn]
Sets a list of rectangles to the clip mask. The
number of arguments must be a multiple of four.
The arguments are coordinates. The parser calcu-
lates the width and height of the rectangles.
Example:
clip-rects 0,0,10,20, 20,10,30,30
coord-mode mode
Changes the coord mode for fill-polygon,
draw-lines, and draw-points. Accepted parameters
are "modeorigin" and "previous", that sets the
coord mode to CoordModeOrigin or CoordModePrevi-
ous, respectively. Example:
coord-mode previous
copy-area {pixmap-spec|.},dstx,dsty[,x2,y2,srcx,srcy]
Calls XCopyArea. The character . means copy
the window contents, pixmap-spec is as defined in
the PIXMAPS sction of this manual page. X2, and
y2 are coordinates of the end copy, not the
width and height; if not defined, the parser
calculates it. Src_x and src_y defaults to
zero. Example:
copy-area Term,10,10
copy-plane {pixmap-
spec|.},dstx,dsty[,x2,y2,srcx,srcy,plane]
Calls XCopyPlane. The character . means copy
the window contents, pixmap-spec is as defined in
the PIXMAPS sction of this manual page. X2, and
y2 are coordinates of the end copy, not the
width and height; if not defined, the parser
calculates it. Src_x and src_y defaults to
zero. Plane defaults to one. Example:
copy-plane star,10,10
dashes i1[...,in]
Sets the dashes for line drawing. Accepts up to
127 arguments. Example:
dashes 3,7 9,10
draw-arc x1,y1,x2,y2[,start-angle,end-angle]
Draws an arc. The four first arguments are the
rectangle enclosing the arc. The two remaining
arguments, if any, are the start and end
angle, in degrees. Example:
draw-arc +0,+0,-1,-1,0,90
draw-rect x1,y1,x2,y2
draw-rectangle x1,y1,x2,y2
Draws a rectangle. Requires four arguments,
that are the start and end coordinates. Exam-
ple:
draw-rect +1,+1,-5,-5
draw-string x,y,"string"
Draws a text string. Requires three argu-
ments, a x coordinate, a y coordinate and a
string. Strings that have white spaces can be
quoted with the " character, the character \ can
also be used, but, you need to escape this char-
acter twice. Example:
draw-string 10,10, "Hello world!"
exposures boolean
Sets the graphics exposures in the GC. Allowed
parameters are a integer or the strings "true",
"false", "on" and "off". Example:
exposures true
fill-arc x1,y1,x2,y2[,start-angle,end-angle]
Like draw-arc, but fills the contents of the arc
with the currently selected foreground. Example:
fill-arc +0,+0,-1,-1,0,180
fill-poly x1,y1 [...,xn,yn]
fill-polygon x1,y1 [...,xn,yn]
Like draw-lines, but fills the enclosed polygon
and joins the first and last point, if they are
not at the same position. Example:
fill-poly +0,+10, +10,+20, +30,+0
fill-rect x1,y1,x2,y2
fill-rectangle x1,y1,x2,y2
Like draw-rect, but fills the contents of the
rectangle with the selected foreground color.
Example:
fill-rect +10,+10,-20,-20
fill-rule rule
Sets the fill rule. Accepted parameters are
"evenodd" and "winding", that sets the fill rule
to EvenOddRule or WindingRule, respectively. Exam-
ple:
fill-rule winding
fill-style style
Sets the fill style. Allowed parameters are
"solid", "tiled", "stippled" and "opaquestippled",
that sets the fill style to FillSolid,
FillTiled, FillStippled or FillOpaqueStippled,
respectively. Example:
fill-style tiled
font font-spec
Sets the font for text functions. Example:
font -*-*-*-R-*-*-*-120-*-*-*-*-ISO8859-1
fg color-spec
foreground color-spec
Like background, but sets the current foreground
color. Example:
foreground blue
mask This command is useful when you want to draw only
in the region that really needs to be repainted.
Requires no arguments.
function function-spec
Sets the specific GC function. Allowed parameters
are "set", "clear", "and", "andreverse", "copy",
"andinverted", "noop", "xor", "or", "nor",

"miter", "round" and "bevel", that sets the
join style to JoinMiter, JoinRound and
JoinBevel, respectively. Example:
join-style round
image {pixmap-spec},xs,ys,[xe,ye]
This function is implemented as a way to quickly
compose complex decorations in widgets. Pixmap-
spec is as defined in the PIXMAPS section of this
manual page, xs and ys are the coodinates from
where start copying the pixmap, xe and ye are
optional (defaults to xs + pixmap.width and ys +
pixmap.height respectively). If the pixmap has a
mask, the copy is masked accordingly. Example:
image pixmap.xpm,0,0,20,20
