Dear Netters, This sounds stupid, but I suddenly realise I don't know how to find the parent of a Xt widget! I know there is a field in the core widget which contains the parent, but I don't know how to get it nicely. Could some kind soul point out how to do it, and where I can find further information? Please email, and I'll summarise. Thanks --- Soh, Kam Hung email: h.soh@trl.oz.au tel: +61 03 541 6403 Telecom Research Laboratories, P.O. Box 249, Clayton, Victoria 3168, Australia

There is a macro in the XmP.h (private functions/methods) called
XtParent. I see no reason why this has been made private, but it
works.
In R4, XtParent() is also a public function, declared in Intrinsic.h.
The macro is still declared in IntrinsicP.h for efficiency.mayer@hplabsz.HPL.HP.COM (Niels Mayer) (08/09/90)
