See reader questions & answers on this topic! - Help others by sharing your knowledge The XtGetValues interface for retrieving resources from a widget is sensitive to the type of variable. Your code may be doing something like this: { Arg args[3]; int i; int sensitive; /* oops; wrong data type */ i=0; XtSetArg (args[i], XtNsensitive, &sensitive); i++; XtGetValues(widget, args, i ); ... } But XtNsensitive is a Boolean, which on most machines is a single byte; declaring the variable "sensitive" as Boolean works properly. This problem comes up often when using particular toolkits that redefine the Xt types Dimension and Position; code that assumes they are int will have similar problems if those types are actually short. In general: you are safe if you use the actual type of the resource, as it appears in the widget's man page.
