focusWin: Set the Focus on a Particular Window

Description

Bring the specified window into focus, and set it as the active window. focusWin will fail to bring the window into focus if it is called from the R console, since the R console returns focus to itself once a function returns. However, it will work if focusWin is called as a result of calling a function from the GUI window. (i.e., pushing a button or any other widget that has a function argument).

Usage

focusWin(winName, winVal=TRUE)

Arguments

winName

name of window to focus

winVal

if TRUE, associate winName with the default window for setWinVal and getWinVal

    "getWinVal()$myvar = ", getWinVal()$myvar, "\n\n", sep="",collapse="")
  cat(mess); invisible()
}
#create three windows named win1, win2, win3
#each having three radio buttons, which are used to change the focus
