Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value. Therefore I want to add tkentry to allow the user to set tkscale to a certain value.
Here is the code library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha", variable="varalpha",showvalue=TRUE, resolution=1, orient="horiz"),side="bottom") tkpack(tkentry(tt,width="10",textvariable="varalpha",validate="key",validatecommand="string is double %P"),side="bottom") As you can see, varalpha is a global variable (I think in tcl, not in R), and if you change the parameter by the scale, the value in tkentry is updated. If I want to set now the value of varalpha by tkentry, it bugs. Does anyone have an idea, why? I already tried the interval from 0 to any number, which works fine... library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=0.00, to=1000, label="alpha", variable="varalpha",showvalue=TRUE, resolution=1, orient="horiz"),side="bottom") tkpack(tkentry(tt,width="10",textvariable="varalpha",validate="key",validatecommand="string is double %P"),side="bottom") Thanks in advance, Alexander -- View this message in context: http://r.789695.n4.nabble.com/set-tkscale-by-tkentry-tp4631174.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org 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.
