tkinter无边框窗体（windows）（二）

设置窗口无边框的方法是用overrideredirect(True)，代码如下：

import tkinter as tk
 
root = tk.Tk()
root.overrideredirect(True)
root.mainloop()

别急划走~~，如果这样设置，状态栏的小图标没有了~。如果你时window系统，我们换个方法，用window的原生接口来解决无边框问题。

方法一：

from tkinter import Tk
from ctypes import Structure, c_long, windll, byref


class RECT(Structure):
    _fields_ = [("left", c_long), ("top", c_long), ("right", c_long), ("bottom", c_long)]


SPI_GETWORKAREA = 48
GWL_STYLE = -16  # 用于获取窗口样式
WS_CAPTION = 12582912  # 窗口标题栏样式
WS_THICKFRAME = 262144  # 窗口可调整边框样式


class WindowTk(Tk):
    def __init__(self, width=1000, height=600):
        super().__init__()
        '''居中显示'''
        work_rect = RECT()
        windll.user32.SystemParametersInfoW(SPI_GETWORKAREA, 0, byref(work_rect), 0)
        self.ww = work_rect.right - work_rect.left
        self.wh = work_rect.bottom - work_rect.top
        size = '%dx%d+%d+%d' % (width, height, (self.ww - width) / 2, (self.wh - height) / 2)
        self.geometry(size)
        '''无边框'''
        self.update_idletasks()  # 刷新窗口状态
        self.hwnd = windll.user32.GetParent(self.winfo_id())  # 获取窗口句柄
        style = windll.user32.GetWindowLongPtrW(self.hwnd, GWL_STYLE)
        style &= ~(WS_CAPTION | WS_THICKFRAME)
        windll.user32.SetWindowLongPtrW(self.hwnd, GWL_STYLE, style)


if __name__ == '__main__':
    root = WindowTk()
    root.mainloop()

方法二：

import tkinter as tk
from ctypes import windll


class BorderlessWindow(tk.Tk):
    def __init__(self):
        super().__init__()
        self.overrideredirect(True)
        self.iconbitmap("logo.ico")  # 图标
        hwnd = windll.user32.GetParent(self.winfo_id())
        windll.user32.ShowWindow(hwnd, 0)  # SW_HIDE
        # 修改窗口样式
        ex_style = windll.user32.GetWindowLongPtrW(hwnd, -20)  # GWL_EXSTYLE
        windll.user32.SetWindowLongPtrW(hwnd, -20, ex_style | 262144)  # WS_EX_APPWINDOW
        # 设置单击任务栏图标可以最小化
        style = windll.user32.GetWindowLongPtrW(hwnd, -16)  # GWL_STYLE
        windll.user32.SetWindowLongPtrW(hwnd, -16, style | 131072)  # WS_MINIMIZEBOX
        # 刷新任务栏
        windll.user32.ShowWindow(hwnd, 5)  # SW_SHOW


if __name__ == "__main__":
    app = BorderlessWindow()
    app.geometry("400x300+500+200")
    app.mainloop()

OK~~
