Examples
tk_getOption .opt result "Option Dialog" "Please choose an option" three one two three four five six
tk_getOption .opt result "Option Dialog" {} "Choose an option" one two three four five six
tk_getOption .opt result "Option Dialog" {} {} one two three four five sixif 0 {
Usage:
tk_getOption w var title text prompt start args
w: toplevel name
var: global variable in which the result is stored
title: title of the toplevel
text: text for the prompt over the option menu, may be set to null if you do not wish for a static prompt
initial: set the initial value, this value does not have to be one of the options, and may be null
args: the values that will be selectable in the option menu }
Have you thought about adding this to tklib?

Both Tk and ttk together

I combined both source codes into one. You can switch using the variable ::tk_getOption_Style
(empty stands for Tk, anything else for ttk, if it is available)
You may test it via the three example lines above. Have a look at the picture for a preview.

||(![info exists ::tk_getOption_Style])} {
set ::tk_getOption_Style ""
}
if {[string length $::tk_getOption_Style]==0} {

} else {
# Make sure ttk will be used! (Older maybe use tile?)
