validator stop checking when the first widget validate False

Hi all!

I have a problem when i doing something at validator, i want to validate all widgets,

and when a widget validate false, it’s background color will be changed.

So, if all widgets validate false, all widget’s background color will be changed,

but the result is when first widget validate false, the rest of widgets don’t be validated.

Is the validator will stop when first widget get false? Or there is something wrong in my code?

Please help me, thanks!

Here is my code:

import wx

import pprint

class DataXferValidator(wx.PyValidator):

def init(self, data, key):

wx.PyValidator.init(self)

self.data = data

self.key = key

def Clone(self):

“”"

Note that every validator must implement the Clone() method.

“”"

return DataXferValidator(self.data, self.key)

def Validate(self, win):

widget = self.GetWindow()

text = widget.GetValue()

if len(text) == 0:

widget.SetBackgroundColour(’#ffcccc’)

widget.SetFocus()

widget.Refresh()

return False

else:

widget.SetBackgroundColour(wx.SystemSettings_GetColour(wx.SYS_COLOUR_WINDOW))

widget.Refresh()

return True

def TransferToWindow(self):

textCtrl = self.GetWindow()

textCtrl.SetValue(self.data.get(self.key, “”))

return True

def TransferFromWindow(self):

textCtrl = self.GetWindow()

self.data[self.key] = textCtrl.GetValue()

return True

class MyDialog(wx.Dialog):

def init(self, data):

wx.Dialog.init(self, None, -1, “Validators: data transfer”)

Create the text controls

about = wx.StaticText(self, -1, about_txt)

name_l = wx.StaticText(self, -1, “Name:”)

email_l = wx.StaticText(self, -1, “Email:”)

phone_l = wx.StaticText(self, -1, “Phone:”)

name_t = wx.TextCtrl(self, validator=DataXferValidator(data, “name”))

email_t = wx.TextCtrl(self, validator=DataXferValidator(data, “email”))

phone_t = wx.TextCtrl(self, validator=DataXferValidator(data, “phone”))

Use standard button IDs

okay = wx.Button(self, wx.ID_OK, ‘OK’)

okay.SetDefault()

cancel = wx.Button(self, wx.ID_CANCEL, ‘Cancel’)

Layout with sizers

sizer = wx.BoxSizer(wx.VERTICAL)

sizer.Add(about, 0, wx.ALL, 5)

sizer.Add(wx.StaticLine(self), 0, wx.EXPAND|wx.ALL, 5)

fgs = wx.FlexGridSizer(3, 2, 5, 5)

fgs.Add(name_l, 0, wx.ALIGN_RIGHT)

fgs.Add(name_t, 0, wx.EXPAND)

fgs.Add(email_l, 0, wx.ALIGN_RIGHT)

fgs.Add(email_t, 0, wx.EXPAND)

fgs.Add(phone_l, 0, wx.ALIGN_RIGHT)

fgs.Add(phone_t, 0, wx.EXPAND)

fgs.AddGrowableCol(1)

sizer.Add(fgs, 0, wx.EXPAND|wx.ALL, 5)

btns = wx.StdDialogButtonSizer()

btns.AddButton(okay)

btns.AddButton(cancel)

btns.Realize()

sizer.Add(btns, 0, wx.EXPAND|wx.ALL, 5)

self.SetSizer(sizer)

sizer.Fit(self)

app = wx.PySimpleApp()

data = { “name” : “Lin zh",“email”:"lin@zh.com”}

dlg = MyDialog(data)

dlg.ShowModal()

dlg.Destroy()

wx.MessageBox(“You entered these values:\n\n” +

pprint.pformat(data))

app.MainLoop()

Yes that is the standard behavior,
I think you could add something like the following to your MyDialog class, there could be some additional problems that I'm not taking into account:

class MyDialog(wx.Dialog)

     def __init__(self, data):

         #your previous code goes here

         self.Bind(wx.EVT_BUTTON, self.onOk, okay)

     def onOk(self, evt):
         allValid = True
         for control in self.GetChildren():
             if isinstance(control, wx.TextCtrl) or isinstance(control, wx.ComboBox): #add to the list every kind of widget to be validated
                 validator = control.GetValidator()
                 if validator:
                     isValid = validator.Validate(control)
                     if not isValid : allValid=False

         if allValid:
             self.EndModal(wx.ID_OK)
         else:
             evt.Skip() #check here what to do as i'm going by memory

Thank you very much, it works very well for me.
