O J*_*JOE 4 python tkinter toplevel
删除最小化和最大化按钮后,是否可以显示我toplevel和root窗口的图标?我尝试使用,-toolwindow但此后无法显示该图标。还有其他方法可以在仍然显示图标的同时从窗口中删除最小和最大尺寸按钮吗?
from tkinter import *
def top():
tp = Toplevel()
tp.geometry("300x300")
tp.attributes("-toolwindow", 1)
tp.iconbitmap("My icon.ico")
root = Tk()
root.geometry("400x400")
b = Button(root, text="open window with icon", command=top).pack()
root.mainloop()

第一种选择是使您的toplevel窗口在窗口中处于瞬态状态,root这是一个非常简单的解决方案。
您需要做的就是将行更改tp.attributes("-toolwindow", 1)为tp.transient(root)!
第二种选择较为复杂,但在Windows系统中更为通用。
在Windows系统中的每个窗口都有自己的风格,这是表示为逻辑分离的位风格。你可以建立从刮痕或设定新的风格,新的风格脱节的旧有位风格(将其打开),或结合旧了的否定位风格(将其关闭) :
new style = old style AND NOT Maximize AND NOT Minimizenew style = old style OR Maximize OR Minimize对于所有这些交互,我们需要ctypes库(Python附带)和一组WinAPI函数:
检查以下示例:
import tkinter as tk
import ctypes
# shortcuts to the WinAPI functionality
set_window_pos = ctypes.windll.user32.SetWindowPos
set_window_long = ctypes.windll.user32.SetWindowLongPtrW
get_window_long = ctypes.windll.user32.GetWindowLongPtrW
get_parent = ctypes.windll.user32.GetParent
# some of the WinAPI flags
GWL_STYLE = -16
WS_MINIMIZEBOX = 131072
WS_MAXIMIZEBOX = 65536
SWP_NOZORDER = 4
SWP_NOMOVE = 2
SWP_NOSIZE = 1
SWP_FRAMECHANGED = 32
def hide_minimize_maximize(window):
hwnd = get_parent(window.winfo_id())
# getting the old style
old_style = get_window_long(hwnd, GWL_STYLE)
# building the new style (old style AND NOT Maximize AND NOT Minimize)
new_style = old_style & ~ WS_MAXIMIZEBOX & ~ WS_MINIMIZEBOX
# setting new style
set_window_long(hwnd, GWL_STYLE, new_style)
# updating non-client area
set_window_pos(hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED)
def show_minimize_maximize(window):
hwnd = get_parent(window.winfo_id())
# getting the old style
old_style = get_window_long(hwnd, GWL_STYLE)
# building the new style (old style OR Maximize OR Minimize)
new_style = old_style | WS_MAXIMIZEBOX | WS_MINIMIZEBOX
# setting new style
set_window_long(hwnd, GWL_STYLE, new_style)
# updating non-client area
set_window_pos(hwnd, 0, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED)
def top():
tp = tk.Toplevel()
# tp.geometry('300x300')
# tp.iconbitmap('icon.ico')
hide_minmax = tk.Button(tp, text='hide minimize/maximize', command=lambda: hide_minimize_maximize(tp))
hide_minmax.pack()
show_minmax = tk.Button(tp, text='show minimize/maximize', command=lambda: show_minimize_maximize(tp))
show_minmax.pack()
root = tk.Tk()
root.geometry('400x400')
b = tk.Button(root, text='open window with icon', command=top)
b.pack()
root.mainloop()
