New submission from Tom Middleton <busfa...@gmail.com>:
Using Tkinter under Python 2.7.1 (Windows XP FWIF)
If using the tkSimpleDialog.askinteger() function with an initialvalue = 0, the
0 is not displayed in the dialog box. The same is true for
tkSimpleDialog.askfloat().
The cause of this seems to be the following:
in Lib\libi-tk\tkSimpleDialog.py (attached for convenience)
under class _QueryDialog(Dialog)
def body(self, master):
w = Label(master, text=self.prompt, justify=LEFT)
w.grid(row=0, padx=5, sticky=W)
self.entry = Entry(master, name="entry")
self.entry.grid(row=1, padx=5, sticky=W+E)
if self.initialvalue:
self.entry.insert(0, self.initialvalue)
self.entry.select_range(0, END)
return self.entry
The if self.initialvalue will evaluate to a FALSE when the initial value is a 0.
Changing this line to:
if self.initialvalue is not None:
fixed this issue.
I am not certain that this is as intended or a bug.
