[issue15303] Minor revision to the BaseWidget._setup method in Tkinter

New submission from Drew French rectangletan...@gmail.com: In the BaseWidget._setup method, master is evaluated as a Boolean (when Tkinter attempts to find a parent for the widget). I think it should really be evaluated against None, seeing as that is the default master keyword argument value

[issue15189] tkinter.messagebox does not use the application's icon

Drew French rectangletan...@gmail.com added the comment: This is also true for some of the other dialogs (such as the file dialogs). Does anyone know if this behavior can be changed in Tk itself? -- nosy: +Drew.French ___ Python tracker rep
