所以，我最近检查了 VsCode，我注意到了一个有趣的功能。虽然有任务栏图标，但没有标题栏；相反，VsCode 实现了自己的。我查看了 Microsoft 的其他一些程序，它们也做同样的事情。我认为这是一个非常酷的功能。
我使用 Tkinter* 制作了很多生产力应用程序，因此我研究了如何在我的应用程序中执行此操作。不幸的是，在 Tkinter 中摆脱标题栏的标准方法是禁用窗口管理器（使用overridedirect(1)）。这也摆脱了我想保留的任务栏图标。
换句话说，我想要得到的是
同时仍然保持这个：
.
* 作为参考，我使用的是 Python 3.8 和 TkInter 8.6。
您可以使用框架创建自己的按钮标题栏。这里看看这个。我还开发了一个基于 tkinter 的应用程序，并使用 @Hruthik Reddy 提供的内容创建了这个应用程序。

假设您可能在这些应用程序中的某个时候使用过类，我创建了这个继承Tk的子类，并在评论中解释：

当窗口最大化时，您可能看不到任务栏。但是您仍然可以使用 sizegrip 调整它的大小。我还不知道如何从窗口边框调整窗口大小，overrideredirect但 Sizegrip 工作得很好。
现在关于set_appwindow功能，这就是 MSDN 所说的：
每当应用程序创建一个不属于自己的窗口时，Shell 就会在任务栏上创建一个按钮。要确保窗口按钮位于任务栏上，请使用 WS_EX_APPWINDOW 扩展样式创建一个无主窗口。要防止窗口按钮被放置在任务栏上，请使用 WS_EX_TOOLWINDOW 扩展样式创建无主窗口。作为替代方案，您可以创建一个隐藏窗口，并使该隐藏窗口成为可见窗口的所有者。
这似乎是一个很长的答案，但我希望它涵盖了您需要的所有内容并为您提供帮助。
查看以下对我有用的代码：-
import tkinter as tk
import tkinter.ttk as ttk
from ctypes import windll
GWL_EXSTYLE=-20
WS_EX_APPWINDOW=0x00040000
WS_EX_TOOLWINDOW=0x00000080
def set_appwindow(root):
hwnd = windll.user32.GetParent(root.winfo_id())
style = windll.user32.GetWindowLongW(hwnd, GWL_EXSTYLE)
style = style & ~WS_EX_TOOLWINDOW
style = style | WS_EX_APPWINDOW
res = windll.user32.SetWindowLongW(hwnd, GWL_EXSTYLE, style)
root.wm_withdraw()
root.after(10, lambda: root.wm_deiconify())
def main():
root = tk.Tk()
root.wm_title("AppWindow Test")
button = ttk.Button(root, text='Exit', command=lambda: root.destroy())
button.place(x=10,y=10)
root.overrideredirect(True)
root.after(10, lambda: set_appwindow(root))
root.mainloop()
if __name__ == '__main__':
main()
在function on_deiconify()我们需要取消绑定之前的事件<FocusIn>以避免我们这样写的窗口的blitting
def on_deiconify(self, event):
""" function to deiconify or window """
self.overrideredirect(True)
set_appwindow(root=self)
self.unbind("<FocusIn>")
