在 Main Window 中单击按钮后，第二个 Window 为空白

Question

我有两个 python 文件，第一个包含主要 Window，第二个 python 文件包含另一个 Window。我设法使第二个 window 出现，但 window 出现后是空白的。这是错误的屏幕截图。

这里是点击 "Configuration" 按钮后应该显示的内容。

在主 window 文件中，我这样定义代码：

from tkinter import *
import configureUAHChange as cA

class TracingInterface(Frame):
    def __init__(self, master):
        super().__init__()
        root.minsize(width=700, height=520)
        root.maxsize(width=700, height=520)
        Frame.__init__(self, master)
        Grid.config(self)
        self.TracingMethod()
        self.logDetails()
        self.otherFunctionInterface()
        # Default window state
        self._configureUA_window = None

    def UAconfig_window(self):
        if self._configureUA_window is not None:
            return
        self._configureUA_window =cA.ConfigureUAinterface(self)

    def closeUA(self):
        # Destroy the 2nd and reset the value to None
        if self._configureUA_window is not None:
            self._configureUA_window.destroy()
            self._configureUA_window = None

此行用于按钮单击命令：

self.configUAButton = Button(self.radioframe, text="Configuration",command=self.UAconfig_window)

接下来，这就是我在第二个 python 文件中定义函数的方式

class ConfigureUAinterface(Toplevel):
def __init__(self, master):
    super().__init__(master)
    master.minsize(width=700, height=520)
    master.maxsize(width=700, height=520)

    Frame.__init__(self, master)
    Grid.config(self)

    master.title("UA Configuration")

    #Pre define combobox value in case suggestion
    self.value_of_combo='Identity Theft'

    #Run the all Function
    self.DateSelection()
    self.finish()
    self.UASuggestion()
    self.ConfigurationUA()
    self.suggestionCombo()

请告诉我如何修改我的代码来解决上述错误。

Answer 1

1）我觉得TracingInterface的__init__函数中有一些root应该是master。

2) 你传递给 ConfigureUAinterface 的母版不是 window 而是 TracingInterface 是一个框架并且没有 minsize, maxsize 和 title 方法。

3) 我不知道你为什么使用 Frame.__init__(self, master) 而 ConfigureUAinterface 继承自 Toplevel.

编辑：主要变化 window:

class TracingInterface(Frame):
    def __init__(self, master):
        super().__init__()

        # 1) master instead of root (it was just a typo I think)
        master.minsize(width=700, height=520)
        master.maxsize(width=700, height=520)
        # Frame.__init__(self, master): redundant with super().__init__()
        Grid.config(self)
        self.TracingMethod()
        self.logDetails()
        self.otherFunctionInterface()
        # Default window state
        self._configureUA_window = None

    def UAconfig_window(self):
        if self._configureUA_window is not None:
            return None
        # 2) changed self which is a frame to the actual window self.master
        self._configureUA_window = cA.ConfigureUAinterface(self.master)

第二次更改 window：

class ConfigureUAinterface(Toplevel):
    def __init__(self, master):
        super().__init__(master)
        # replaced master by self since it's the Toplevel size we want to limit
        self.minsize(width=700, height=520)
        self.maxsize(width=700, height=520)

        # 3) The following is inapropriate since the widget 
        #    inherit from Toplevel, not Frame:
        #  Frame.__init__(self, master)
        #  Grid.config(self)

        # replaced master by self since it's the Toplevel title
        self.title("UA Configuration")

        #Pre define combobox value in case suggestion
        self.value_of_combo='Identity Theft'

        #Run the all Function
        self.DateSelection()
        self.finish()
        self.UASuggestion()
        self.ConfigurationUA()
        self.suggestionCombo()

我没有修改代码中的任何其他内容，当我尝试时，它成功了。
