Hello;
I've got several radiobuttons in tcltk with the following sintaxis:
tk2.rd <- /tkradiobutton(/frame4,command=plotDialog1,text="New Q plot",
value=2, variable=OUTPLOTtclVar/)/
All the buttons call the same function "plotDialog1". With the objective
of call a dialog to select some plotting options.
When I select one of the radiobuttons and the windows with the plotting
options appears. It appears blank, and I obtain this message of error in R:
> Error in structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"),
class = " tclObj") :
[tcl] grab failed: window not viewable.
All radio buttons are within a frame in a window named "dlg". I've
removed nearly everything in this function and I still obtain the same
error when clicking on a radiobutton.
Even with this very simple remaining code:
plotDialog1 <- function/()/ {
mddlg2 <- /tktoplevel()/
tkwm./deiconify(/mddlg2/)/
tkgrab./set(/mddlg2/)/
tkwm./title(/mddlg2,"Plot options"/)/
onNO <- function/()/
{
tkgrab./release(/mddlg2/)/
/tkdestroy(/mddlg2/)/
/tkfocus(/dlg/)/
}
// NO.but <- /tkbutton(/mddlg2,text=" Cancel ",command=onNO/)/
/tkgrid(/NO.but,pady=2/)/
/tkfocus(/mddlg2/)/
tkwait./window(/mddlg2/)/
}
Please for those who are used to utilize the tcltk library: ¿Can you see a
clear error in this?
I'm new to this library and tcltk and I'm unable to find out the error.
Thanks and best regards,
Javier
