我正在做一个项目，我去掉了根窗口。我自己做了。我有它的工作，但我一直无法找到最小化窗口的方法。
我尝试使用 root.iconify() 并设置了 root.root.overrideredirect(True)。但它给了我以下错误:TclError: can't iconify ".": override-redirect flag is set。
如何在不出现此错误的情况下最小化窗口，以及它像普通根窗口一样将其最小化的位置。
代码:
from Tkinter import *
import time
import os
class Application(Frame):
def __init__(self, parent):
Frame.__init__(self,parent)
self.pack(fill=BOTH)
self.create_widgets()
def create_widgets(self):
self.borderFrame = Frame(self, width=500, height=600, bg="Gray")
self.borderFrame.pack_propagate(False)
self.borderFrame.pack(side=TOP)
self.holderFrame = Frame(self.borderFrame, width=500, height=570, bg="blue")
self.holderFrame.pack_propagate(False)
self.holderFrame.pack(side=BOTTOM)
self.close = Label(self, font=("Arial", 11), bg="Gray", anchor=CENTER, text="X", cursor="hand2")
self.close.place(x=460, y=0, width=40, height=30)
self.min = Label(self, font=("Arial", 11), bg="Gray", anchor=CENTER, text="_", cursor="hand2")
self.min.place(x=420, y=0, width=40, height=30)
def hoverMin(event):
event.widget.config(bg="lightBlue")
def unHoverMin(event):
event.widget.config(bg="Gray")
self.min.bind("<Enter>", hoverMin)
self.min.bind("<Leave>", unHoverMin)
self.min.bind("<Button-1>", self.minimize)
def hover(event):
event.widget.config(bg="red")
def unhover(event):
event.widget.config(bg="Gray")
self.close.bind("<Enter>", hover)
self.close.bind("<Leave>", unhover)
self.close.bind("<Button-1>", self.exitProgram)
self.borderFrame.bind("<Button-1>", self.startMove)
self.borderFrame.bind("<ButtonRelease-1>", self.stopMove)
self.borderFrame.bind("<B1-Motion>", self.moving)
def startMove(self, event):
self.x = event.x
self.y = event.y
def stopMove(self, event):
self.x = None
self.y = None
def moving(self,event):
x = (event.x_root - self.x - self.borderFrame.winfo_rootx() + self.borderFrame.winfo_rootx())
y = (event.y_root - self.y - self.borderFrame.winfo_rooty() + self.borderFrame.winfo_rooty())
root.geometry("+%s+%s" % (x, y))
def minimize(self, event):
root.iconify()
def exitProgram(self, event):
os._exit(0)
root = Tk()
root.title("Draggable Root")
root.geometry("500x600")
root.overrideredirect(True)
app = Application(root)
root.mainloop()
最佳答案
调用 overrideredirect(True) 向窗口管理器声明您将处理您自己的所有窗口管理。图标化是窗口管理器的事情。如果您只想隐藏窗口，则将最小化函数更改为 root.state('withdrawn') 即可。调用 root.state('normal') 再次显示窗口。
为了出现在任务栏中，您需要在调用 root.state('iconic') 之前调用 root.overrideredirect(False) 并且在此之前您需要调用 root.update_idletasks()。查看最小化方法的更改。
为了让窗口恢复到您想要的状态，我创建了一个新方法“frame_mapped”并将其绑定(bind)到 borderFrame 上的 Map 事件。当一个小部件被几何管理器(pack/place/grid)处理时， map 事件就会发生。因此，当您单击任务栏取消最小化时，将触发“frame_mapped”再次调用 overrideredirect(True)。
