Passing a variable that contains two words to a combobox

[MrE4U]

Here is my problem:

set testvar "Testing Testing"
ComboBox .updateentry.cupdate -values $testvar

and the result is:

Testing
Testing

in the combobox, but I want it to do this:

Testing Testing

I can set it up has a literal and it works such as the following:

ComboBox .updateentry.cupdate -values {"Testing Testing"}

and the result in the Combobox is:

Testing Testing

I have been messing around with the brackets and quotes and I cannot get it to work right.

The reason the following is working when you set it up as a literal - ComboBox .updateentry.cupdate -values {"Testing Testing"} - is because the value is defined as 1 element list.

In your inital set testvar "Testing Testing", it's nothing more then a string.

For kicks, try this for now ...

set testvar {"Testing Testing"}
