You haven't shown the code for common_classes.LabelInput, but I'm guessing
that the first argument should be the parent.
Here's the LabelInput class:
class LabelInput(tk.Frame):
""" A widget containing a label and input together. """
def __init__(self, parent, label='', input_class=ttk.Entry,
input_var=None, input_args=None, label_args=None,
**kwargs):
super().__init__(parent, **kwargs)
label_args = label_args or {}
input_args = input_args or {}
self.variable = input_var,
if input_class in (ttk.Checkbutton, ttk.Button, ttk.Radiobutton):
input_args["text"] = label
input_args["variable"] = input_var
else:
self.label = ttk.Label(self, text=label, **label_args)
self.label.grid(row=0, column=0, sticky=(tk.W + tk.E))
input_args["textvariable"] = input_var
self.input = input_class(self, **input_args)
self.input.grid(row=1, column=0, sticky=(tk.W + tk.E))
self.columnconfigure(0, weight=1)
self.error = getattr(self.input, 'error', tk.StringVar())
self.error_label = ttk.Label(self, textvariable=self.error)
self.error_label.grid(row=2, column=0, sticky=(tk.W + tk.E))
def grid(self, sticky=(tk.E + tk.W), **kwargs):
super().grid(sticky=sticky, **kwargs)
def get(self):
try:
if self.variable:
return self.variable.get()
elif type(self.input) == tk.Text:
return self.input.get('1.0', tk.END)
else:
return self.input.get()
except (TypeError, tk.TclError):
# happens when numeric fields are empty.
return ''
def set(self, value, *args, **kwargs):
if type(self.variable) == tk.BooleanVar:
self.variable.set(bool(value))
elif self.variable:
self.variable.set(value, *args, **kwargs)
elif type(self.input) in (ttk.Checkbutton, ttk.Radiobutton):
if value:
self.input.select()
else:
self.input.deselect()
elif type(self.input) == tk.Text:
self.input.delete('1.0', tk.END)
self.input.insert('1.0', value)
else:
self.input.delete(0, tk.END)
self.input.insert(0, value)
You're passing in the _class_ ConactNameInput, but I'm guessing that it
should be an _instance_ of that class, in this case, 'self'.
Haven't I done this in the application class?
class NameApplication(tk.Tk):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.title("Contact Name")
self.geometry("800x600")
self.resizable(width = False, height = False)
ContactNameInput(self).grid(row = 0, column = 0, sticky=('EWNS'))
self.columnconfigure(0, weight=1)
If not, where do I specify the instance of the ContactNameInput class?
Thanks,
Rich
