找不到ttk样式的布局该如何解决？

如何解决找不到ttk样式的布局该如何解决？

我正在制作自己的自定义菜单栏。我的工作正在进行中，但是最近我遇到了一个混乱。这是我的代码：-

from tkinter import *
from tkinter.ttk import Style,Frame as fp
class menu():
    def __init__(self,parent,bg="#ffffcc"):
        self.parent = parent
        self.bg = bg
        #this is a image in base 64 encoded format
        borderImageData='''

        self.borderImage = PhotoImage( data=borderImageData,master=self.parent)
        self.TP_style=Style()
        self.TP_style.element_create("RoundedFrame","image",self.borderImage,border=14,sticky="nsew")
        self.TP_style.layout("RoundedFrame",[("RoundedFrame",{"sticky": "nsew"})])
        self.frame_one = fp(parent,style="RoundedFrame",padding=10,width=100,height=100)
        self.frame_one.pack()
        l1=Label(parent,image=self.borderImage).pack()
    def popup(self,x,y,width=110,height=120):
        self.width=width
        self.height=height
        self.app = Tk()
        self.app.config(bg=self.bg)
        self.app.geometry(f"{self.width}x{self.height}+{x}+{y}")
        self.app.wm_attributes("-topmost",True)
        self.app.overrideredirect(True)
        self.app.focus_force() 
        #self.frame_one = fp(self.app,height=100)
        #self.frame_one.pack()
        #l1=Label(self.app,image=self.borderImage).pack()
        #self.m.pack_propagate(0)
        def destroy(event):
            self.app.destroy()
        self.app.bind("<FocusOut>",destroy)
if __name__ == "__main__":
    root = Tk()
    menu = menu(root)
    def evt(evt):
        menu.popup(evt.x_root,evt.y_root,width=200,height=400)     
    root.bind("<Button-3>",evt)
    root.mainloop()

如果我为框架写样式

self.frame_one = fp(parent,height=100)

在 init （）方法中，一切正常。如果我在弹出窗口methon中写了同样的东西（我刚刚在其中注释掉了），则出现以下错误。

Exception in Tkinter callback
    Traceback (most recent call last):
      File "C:\Users\mishra\AppData\Local\Programs\Python\python38-32\lib\tkinter\__init__.py",line 1883,in __call__
        return self.func(*args)
      File "C:\Users\mishra\P_Menu.py",line 64,in evt
        menu.popup(evt.x_root,height=400)
      File "C:\Users\mishra\P_Menu.py",line 51,in popup

    _tkinter.TclError: Layout RoundedFrame not found

与Lable相同

l1=Label(self.app,image=self.borderImage).pack()

在 init （）部分中，一切正常，但在弹出方法中出现以下错误。

Traceback (most recent call last):
  File "C:\Users\mishra\AppData\Local\Programs\Python\python38-32\lib\tkinter\__init__.py",in __call__
    return self.func(*args)

_tkinter.TclError: image "pyimage1" doesn't exist

我想知道如何解决它，因为我想知道它背后的逻辑并在popup（）方法中使用。任何帮助将被申请。谢谢！

解决方法

也许是因为popup以Tk的形式创建了一个新的self.app实例，但是样式属于Tk创建的第一个root = Tk()实例。因此，第二个Tk实例的子代无法识别它。也许您可以尝试将self.app = Tk()更改为self.app = Toplevel()以查看其是否有效？
