I need help implementing some form of validation into my application. I have a wx.TextCtrl control which accepts a valid URL from the user. I would like to validate the URL before it is passed on to the Requests library and to bs4 library further on.
So, what's the way to do it? I would like to avoid any regexes if possible.
My current implementation is the following...
"""
The module validatortest is intended for validating a URL given by the
user in a text control window/widget.
"""
import wx
class ValidateURL(wx.Validator):
"""
Create the validator object.
"""
def __init__(self):
"""
Initialize the validator.
"""
super().__init__()
def Clone(self):
"""
Clone the validator.
"""
return ValidateURL()
def Validate(self, window):
"""
Do URL validation.
"""
pass
# First implementation
#
# textField = self.GetWindow()
# textFieldValue = textField.GetValue()
# Alternative?
#
# textField = window.Get()
# textFieldValue = textField.GetValue()
# Perhaps even this?
#
# textFieldValue = window.GetValue()
# import validators
# try:
# if validators.url(textFieldValue):
# return True
# except ValidationFailure:
# wx.MessageBox(caption="Validation Failure",
# message="Please input a valid URL address form.",
# style=wx.OK | wx.ICON_ERROR)
# return False
def TransferToWindow(self):
"""
This method is called when the value associated with the
validator must be transferred to the window/widget.
"""
return True
def TransferFromWindow(self):
"""
This method is called when the value in the window/widget must
be transferred to the validator.
"""
return True
