| Description: |
If you specify multiple droptypes to DropSite::register
and one of the later droptypes does not contain all of
the operations that an earlier type supported, the
command will cause an error:
toplevel .f
frame .f.fr
DropSite::register .f.fr -dropcmd foo -dropovercmd bar
-droptypes {ABC {copy {} move {}} DEF {copy {}}}
can't read "drop(DEF,mod,4)": no such variable
I'm not sure about the BWidget drag'n'drop internals,
but I believe the problem is caused by the failure to
clear the "masklist" variable in dropsite.tcl:
