prompt-toolkit:在VSplit或HSplit中动态添加和删除缓冲区？

from prompt_toolkit import Application
from prompt_toolkit.buffer import Buffer
from prompt_toolkit.layout import VSplit, Window
from prompt_toolkit.layout.controls import BufferControl
from prompt_toolkit.layout.containers import Container
from prompt_toolkit.key_binding import KeyBindings

# 创建缓冲区和控件
buffer1 = Buffer()
buffer2 = Buffer()
buffer3 = Buffer()

control1 = BufferControl(buffer=buffer1)
control2 = BufferControl(buffer=buffer2)
control3 = BufferControl(buffer=buffer3)

# 创建布局
layout = VSplit([
    Window(content=control1),
    Window(content=control2),
])

# 创建应用程序
application = Application(layout=layout, key_bindings=KeyBindings())

# 运行应用程序
application.run()

# 动态添加和删除缓冲区
layout.children.append(Window(content=control3))
layout.children.remove(control2)
