Snit has a "myvar" method that returns the fully qualified name of a snit member variable. Perhaps something similiar (a method that returned a "reference" to an instance variable) would be useful in XOTcl?
I use the following two global procs for that:
proc myproc {args} {linsert $args 0 [uplevel 1 self]} proc myvar {var} {return [uplevel 1 self]::$var}
The procs are global (not instprocs on "Object") because otherwise I would have to write "my myvar" or "my myproc". Now I can simply use them in the following way inside xotcl (inst)procs:
button $x -command [myproc show 1 2 3] ... trace add variable [myvar status] write [myproc statusevent] ... vwait [myvar done]
(Note: in fact the "uplevel" in the definition of myproc/myvar is not even necessary. It seems that [self] always refers to the last Xotcl object on the callstack.)
