如何在mac触摸栏中显示tkinter按钮

在Mac触摸栏中显示tkinter按钮，可以通过以下步骤实现：

导入必要的库和模块：

import tkinter as tk
from tkinter import ttk
from AppKit import NSApplication, NSAppearance, NSAppearanceNameAqua, NSAppearanceNameDarkAqua

创建一个Tkinter窗口并隐藏它：

root = tk.Tk()
root.withdraw()

创建一个自定义的NSWindow子类，用于在触摸栏中显示按钮：

class TouchBarWindow(NSWindow):
    def init(self):
        self = super().initWithContentRect_styleMask_backing_defer_(
            NSMakeRect(0, 0, 200, 30),  # 按钮在触摸栏中的尺寸
            NSBorderlessWindowMask,  # 创建一个无边框窗口
            NSBackingStoreBuffered,
            False
        )
        if self:
            self.setOpaque_(False)  # 设置窗口透明
            self.setBackgroundColor_(NSColor.clearColor())  # 设置背景颜色为透明
            self.setLevel_(NSStatusWindowLevel)  # 设置窗口级别为状态栏级别
            self.setIgnoresMouseEvents_(True)  # 忽略鼠标事件
            self.setCanBecomeVisibleWithoutLogin_(True)  # 允许在登录前显示
            self.setTitlebarAppearsTransparent_(True)  # 设置标题栏透明
            self.setTitleVisibility_(NSWindowTitleHidden)  # 隐藏标题栏
            self.setAppearance_(NSAppearance.appearanceNamed_(NSAppearanceNameAqua))  # 设置外观为Aqua模式
            self.setFrameAutosaveName_("TouchBarWindow")  # 设置窗口自动保存名称
        return self

创建一个按钮并将其添加到自定义的NSWindow中：

def create_button():
    button = ttk.Button(text="Button")  # 创建一个tkinter按钮
    button.pack()
    button.update()
    button_frame = button.winfo_toplevel()  # 获取按钮所在的顶级窗口
    button_frame.bind("<Configure>", resize_button)  # 监听按钮窗口的大小变化事件
    return button

def resize_button(event):
    button_frame = event.widget
    button = button_frame.children["!button"]
    button.update()
    button_frame.update()
    button_frame["width"] = button.winfo_width()
    button_frame["height"] = button.winfo_height()

button = create_button()

window = TouchBarWindow.alloc().init()
window.contentView().addSubview_(button)

运行NSApplication主循环以显示触摸栏按钮：

NSApplication.sharedApplication().run()

完整的代码示例如下：

import tkinter as tk
from tkinter import ttk
from AppKit import NSApplication, NSAppearance, NSAppearanceNameAqua, NSAppearanceNameDarkAqua, NSWindow, NSMakeRect, NSBorderlessWindowMask, NSBackingStoreBuffered, NSStatusWindowLevel, NSColor, NSWindowTitleHidden

root = tk.Tk()
root.withdraw()

class TouchBarWindow(NSWindow):
    def init(self):
        self = super().initWithContentRect_styleMask_backing_defer_(
            NSMakeRect(0, 0, 200, 30),
            NSBorderlessWindowMask,
            NSBackingStoreBuffered,
            False
        )
        if self:
            self.setOpaque_(False)
            self.setBackgroundColor_(NSColor.clearColor())
            self.setLevel_(NSStatusWindowLevel)
            self.setIgnoresMouseEvents_(True)
            self.setCanBecomeVisibleWithoutLogin_(True)
            self.setTitlebarAppearsTransparent_(True)
            self.setTitleVisibility_(NSWindowTitleHidden)
            self.setAppearance_(NSAppearance.appearanceNamed_(NSAppearanceNameAqua))
            self.setFrameAutosaveName_("TouchBarWindow")
        return self

def create_button():
    button = ttk.Button(text="Button")
    button.pack()
    button.update()
    button_frame = button.winfo_toplevel()
    button_frame.bind("<Configure>", resize_button)
    return button

def resize_button(event):
    button_frame = event.widget
    button = button_frame.children["!button"]
    button.update()
    button_frame.update()
    button_frame["width"] = button.winfo_width()
    button_frame["height"] = button.winfo_height()

button = create_button()

window = TouchBarWindow.alloc().init()
window.contentView().addSubview_(button)

NSApplication.sharedApplication().run()

这样，你就可以在Mac触摸栏中显示一个名为"Button"的tkinter按钮了。请注意，这个方法只适用于Mac系统，并且需要在Python 3.7及以上版本中运行。
