[issue27939] Tkinter mainloop raises when setting the value of ttk.LabeledScale

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

This is caused by replacing int() by self._tk.getint() in IntVar.get() (issue23880). But the failure can be reproduced even in 3.4 if set tk.wantobjects = 0 before creating root widget.

One way is making getint() accepting floats. This fizes original example, but doesn't solve the issue for tk.wantobjects = 0.

Other way is making IntVar.get() falling back to integer part of getdouble(). This fixes the example in both modes. Proposed patch goes this way.
