Problem with 'unicode' object

Hi ,
I’m struggling with Colour. I want to change the color of certain words based on a list.
But I faced to error : “AttributeError: ‘unicode’ object has no attribute ‘SetForegroundColour’”
I know that the format maybe wrong , but don’t know how to change it :

def onChange(self, event):

    string1 = self.entry1.GetValue()
    string2 = ''
    words = string1.split()
    for j in range(len(words)):
        was = False
        for i in range(len(list)):
            if words[j] == list[i]:
                #string2 += ' ' + (words[j])
                string2 += ' ' + (words[j].SetForegroundColour(wx.Color(255, 0, 0)))
                was = True
        if was == False:
            string2 += ' ' + words[j]
    self.display.SetValue(string2)

Any idea ?

Thanks

You get that error because you are trying to call SetForegroundColour on a python string object – that is never going to work, you could only call a method like that on a ax object.

···

I don’t think a regular text entry object supports multiple colors-- you will need to use a widget that does – maybe text control or rich text control.

But in any case, you will be making a call on the ax object that holds the text – not the text itself.

As Chris said, while I was composing this reply, a unicode string doesn’t have any way of specifying how it is displayed, only the object that is presenting the string can do that. In your case self.display is a wx.TextCtrl and I believe you can specify how different ranges of the whole text string are displayed using its SetStyle method to use a wx.TextAttr to set the attributes of the each specified range. You can do similar things with a wx.RichTextCtrl plus use BeginTextColour and EndTextColour as you build the text to be displayed. See the code for the RichTextCtrl in the wxPython Demo.
