英文:

I have a chatbox and I'm trying to colour every message with a different colour

  1. class ChatDisplayer(RichTextCtrl):
  2. def __init__(self, *args, **kw):
  3. super().__init__(*args, **kw)
  4. def addMessage(self, message, red, green, blue):
  5. font = Font(12, DEFAULT, NORMAL, NORMAL, False)
  6. text_attr = RichTextAttr()
  7. text_attr.SetTextColour(BLACK)
  8. text_attr.SetFont(font)
  9. bg_color = Colour(red=red, green=green, blue=blue)
  10. text_attr.SetBackgroundColour(bg_color)
  11. self.BeginStyle(text_attr)
  12. self.AppendText(message)
  13. self.EndStyle()

this does append the text but it does not change the colour of the text of the background colour.
I can find the SetBackgroundColor attribute in the source code but not in the doc.

The main class is complex but looks like this:

  1. class ChatMessageGrid(FlexGridSizer):

  3. super().__init__(6, 2, 9, 25)

  8. chat_message_system_label = StaticText(panel, label="System")
  9. chat_message_system_input = TextCtrl(panel)
  10. chat_message_label = StaticText(panel, label="your message")

I assume it is because you are appending the text and it is using the attributes that are currently in force at that position.
你假设是因为你正在“添加”文本，并且它使用当前位置上生效的属性。

Your options would be to change the attributes at the current position or insert the text with a write and new attributes.
你的选择是更改当前位置的属性或使用write和新属性插入文本。

e.g.
例如。

import wx
导入 wx
import wx.richtext
导入 wx.richtext

class MainFrame(wx.Frame):
类 MainFrame(wx.Frame):

  1. def __init__(self):
