Wie kann ich die Farbe bestimmter Wörter in wxPython TextCtrl ändern?

Question

Ich habe eine GUI erstellt, die nur ein Angebot anzeigt. Wie kann ich die Farbe des Wortes "du" im unten stehenden Zitat in blau ändern? Ich habe versucht SetForegroundColour, aber es ändert den gesamten Text in blau. Hier

ist der Code:

import wx 

string='''"Have more than thou showest, 

Speak less than thou knowest, 

Lend less than thou owest, 

Ride more than thou goest, 

Learn more than thou trowest, 

Set less than thou throwest."

class Quote(wx.Frame): 
    def __init__(self, *args, **kwargs): 
     super().__init__(*args, **kwargs) 
     self.InitUI() 

    def InitUI(self): 
     panel=wx.Panel(self) 

     self.text=wx.TextCtrl(panel, pos=(20,20), size=(250,220), 
      style=wx.TE_MULTILINE|wx.TE_READONLY) 
     self.text.AppendText(string) 
     self.text.SetForegroundColour("blue") 

     self.SetSize(300,300) 
     self.Centre() 
     self.Show(True) 

def main(): 
    app=wx.App() 
    Quote(None) 
    app.MainLoop() 

if __name__ == '__main__': 
    main() 

Here's how it looks like

Sie müssen wahrscheinlich auf lesen RichTextCtrlhttps://wxpython.org/Phoenix/docs/html/richtextctrl_overview.html

Nur TextCtrl verwenden, können Sie
Set-Stil nach der Tat Attribute (Danke Robin für deinen Kommentar) oder
wenden Sie Stil-Attribute auf den Text, wie Sie gehen.

Rahmen Stilattribute nach der Tat re mit allen Vorkommen des Wortes finden vorher:

import wx 
import re 

string='''"Have more than thou showest, 

Speak less than thou knowest, 

Lend less than thou owest, 

Ride more than thou goest, 

Learn more than thou trowest, 

Set less than thou throwest."

class Quote(wx.Frame): 
    def __init__(self, *args, **kwargs): 
     wx.Frame.__init__(self, None, -1) 
     self.InitUI() 

    def InitUI(self): 
     panel=wx.Panel(self) 
     word = 'thou' 
     word_colour = wx.TextAttr(wx.BLUE) 
     word_occurs = self.find_str(word,string) 
     self.text=wx.TextCtrl(panel, pos=(20,20), size=(250,220), 
      style=wx.TE_MULTILINE|wx.TE_READONLY) 
     self.text.AppendText(string) 
     for i in word_occurs: 
      #SetStyle(start pos, end pos, style) 
      self.text.SetStyle(i,i+len(word),word_colour) 
     self.SetSize((300,300)) 
     self.Centre() 
     self.Show(True) 

    def find_str(self,sub,sent): #return positions of the word 
     return [x.start() for x in re.finditer(sub,sent)] 

def main(): 
    app=wx.App() 
    Quote() 
    app.MainLoop() 

if __name__ == '__main__': 
    main() 

Die lange umständliche Art und Weise, dies zu tun, Stil anwenden Attribute, wie Sie gehen:

import wx 

string1='''"Have more than''' 
string2='''showest, 

Speak less than''' 
string3='''knowest, 

Lend less than''' 
string4='''owest, 

Ride more than''' 
string5='''goest, 

Learn more than''' 
string6='''trowest, 

Set less than''' 
string7='''throwest."
