Hi! I've constructed a small menu-driven interface to a couple of R functions using the possibilities offered by the tcltk package. When user runs some specific analyses, I would then like to disable some of the menus (or menu choises) that are not applicable after the performed analysis. I tried to modify the state of an existing menu, but it seems that neither tkconfigure nor tkentryconfigure contains the state as one of its options.
Here's a snip of the code. How could I disable, for example, the Edit data menu choise after already creating the menu (I want it to be active initially)? gui<-tktoplevel() topMenu<-tkmenu(gui) tkconfigure(gui,menu=topMenu) editMenu<-tkmenu(topMenu, tearoff=FALSE) tkadd(editMenu, "command", label="Edit data", command=function() editData()) tkadd(editMenu, "command", label="Preferences", command=function() editPref()) tkadd(topMenu, "cascade", label="Edit", menu=editMenu) Thanks, Jarno Tuimala ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
