问题描述
我正在尝试将用户输入的右侧(使用tkinter python)与scrolledtext对齐，并将chatbot的输出与左侧对齐，但没有成功.文本背景也应具有浅色.我的意思是，它应该看起来像Messenger或其他消息传递平台，双方都有不同的方面，有时甚至是颜色.请帮助我，这是我最后一年项目的一部分.我对此很担心.这是我的代码:
i'am trying to align the user input on right side (using tkinter python) in scrolledtext and chatbot's output on left side but no success.also the text beckground should have light color. i mean it should be just look like messanger or other messaging platform where both sides have different sides and sometimes colors.please help me its a part of my final year project.m very worried about it.here is my code:

推荐答案
您可以使用标签将属性分配给部分文本.
You can use tags to assign properties to part of text.
使用 justify ，您可以在右侧显示文本，但所有行都将在右侧对齐.
Using justify you can have text on right side but all lines will be aligned to the right.
import tkinter as tk
import tkinter.scrolledtext as ScrolledText
root = tk.Tk()
#text_widget = tk.Text()
text_widget = ScrolledText.ScrolledText()
text_widget.pack(fill='both', expand=True)
text_widget.tag_configure('tag-center', justify='center')
text_widget.tag_configure('tag-left', justify='left')
text_widget.tag_configure('tag-right', justify='right')
text_widget.insert('end', 'Hello\nWorld!!!\n', 'tag-center')
text_widget.insert('end', 'Hello\nWorld!!!\n', 'tag-left')
text_widget.insert('end', 'Hello\nWorld!!!\n', 'tag-right')
root.mainloop()
为了更好地控制，您可以尝试将 Canvas 与 Labels 和 Scrollbar
For better control you would try to use Canvas with Labels and Scrollbar
您可以使用 window_create 将 Label 添加到 ScrolledText ，并使用上一个标记将其移至正确的.然后，您可以更改 Label -颜色，边距(padx，pady)等.您可以尝试在图像中添加 Label 甚至是 Frame 放置更多不同的小部件.
Using window_create you can add Label to ScrolledText and using previous tag you can move it to the right. And then you can change Label - color, margin (padx, pady), etc. You may try to add Label with image or even Frame to put more different widgets.
import tkinter as tk
import tkinter.scrolledtext as ScrolledText
root = tk.Tk()
#text_widget = tk.Text()
text_widget = ScrolledText.ScrolledText()
text_widget.pack(fill='both', expand=True)
label1 = tk.Label(text_widget, text="Hello\nWorld!!!", background='#d0ffff', justify='left', padx=10, pady=5)
label2 = tk.Label(text_widget, text="Hello\nWorld!!!", background='#ffffd0', justify='left', padx=10, pady=5)
label3 = tk.Label(text_widget, text="Hello\nWorld!!!", background='#d0ffff', justify='left', padx=10, pady=5)
text_widget.tag_configure('tag-left', justify='left')
text_widget.tag_configure('tag-right', justify='right')
text_widget.insert('end', '\n')
text_widget.window_create('end', window=label1)
text_widget.insert('end', '\n ', 'tag-right') # space to move Label to the right
text_widget.window_create('end', window=label2)
text_widget.insert('end', '\n')
text_widget.window_create('end', window=label3)
root.mainloop()
