[comp.windows.x.motif] Extension Records in Motif Widgets?

ables@wiffle.techbook.com (scott ables) (03/06/91)

I need to extend Motif widgets.  They have extension records, just as the 
Xt Intrinsics do.  But, I can't find any documentation to suggest that 
OSF is going to treat their extension records the same way Xt does, i.e. 
always using the same first four elements (including an id) and when 
accessing the extension record looping through each of them (Xt allows 
nesting of extension records) until Xt finds "its'" extension record 
before accessing the extension record.  I think I noticed a macro in 
Motif that called a function (its late, maybe that was in Xt) if the 
first extension record wasn't OSF's to loop through until OSF found 
theirs.  Anyway, does anyone know anything about OSF's plans for these 
widget extension records?  Can "Widget Smith's" use them with impunity?
thanks, Scott Ables
