The file tkMessageBox.py that comes with Python has this:

def askyesno(title=None, message=None, **options):
    "Ask a question; return true if the answer is yes"
    s = _show(title, message, QUESTION, YESNO, **options)
    return s == YES


So instead of calling askyesno, I used this:

def makeClean():
    r =  tkMessageBox._show('Make clean', 'Remove all files created by Make?', 'question', 'yesno')
    print type(r), r

Call makeClean(), click no, result: <type 'str'> no
Call makeClean(), click yes, result: <type 'str'> yes
Call openProject(), click cancel
Call makeClean(), click no, result: <type 'str'> no
Call makeClean(), click yes, result: <type 'bool'> True

Now, how did that happen?
