Tkinter compound is an attribute that can be used with certain Tkinter widgets, such as the Label widget, to specify how multiple lines of text should be displayed.
By default, text in a Label widget is displayed on a single line, and any text that exceeds the width of the widget is truncated. However, when the compound attribute is set to a value other than "none", the Label widget will display multiple lines of text, with each line separated by a newline character ("\n").
The compound attribute can be set to one of four values:
- "none": This is the default value, and causes the Label widget to display a single line of text.
- "top": This value causes the Label widget to display multiple lines of text, with the first line aligned to the top of the widget.
- "bottom": This value causes the Label widget to display multiple lines of text, with the last line aligned to the bottom of the widget.
- "center": This value causes the Label widget to display multiple lines of text, with each line centered within the widget.
Here's an example of how to use the compound attribute to display multiple lines of text in a Label widget:
```python
import tkinter as tk
root = tk.Tk()
label = tk.Label(root, text="First line\nSecond line\nThird line", compound="center")
label.pack()
root.mainloop()
```
In this example, the Label widget displays three lines of text, with each line centered within the widget. The "\n" characters are used to separate the lines of text.
