Question

我用tkinter创建了几个单独的窗口，现在我想连接它们。因此，实现了几个“前进”和“后退”按钮。这应该很简单，但事实证明，这确实让我很困惑。

这可以看作是此问题的实际应用问题： Go back and forth between tkinter windows

我尽我所能，但仍然失败了。

我的具体问题是：

当我点击“报告”按钮时，将打开新窗口，但是：原始窗口（座舱）没有消失，第二个窗口打开这只是“原始驾驶舱”窗口，但其中没有任何小部件它（只是框架？）
当我按下“后退”按钮时，也会出现此错误消息： self.ReportSelection_Win.withdraw（）AttributeError：“事件”对象没有属性'ReportSelection_Win'

我剥离了以下大多数功能的代码，因为它们对于我认为的问题不是必需的。因此大多数按钮没有任何功能。

from tkinter import * 
from tkinter import ttk

def Func_Show_Rep(self):    
    # Open new Window
    ReportSelection_Win = Tk()
    self.ReportSelection_Win = Toplevel()  

    ReportSelection_Win.title("Report auswählen")

    #Dropdown Auswahlliste
    Reports = [

我将您的代码减少到几乎无用的情况。

from tkinter import * 
from tkinter import ttk  


#Funktionen für Fenster   
def Func_Show_Rep(even = None):
    global Cockpit_Win
    Cockpit_Win.withdraw()#.deiconify() to show again
    ReportSelection_Win = Toplevel() 
    Show_Rep(ReportSelection_Win, Cockpit_Win)

class Show_Rep():    
    # Hide old Window

    def __init__(self, master, Cockpit_Win):
        # Open new Window

        self.ReportSelection_Win =master 
        self.ReportSelection_Win.title("Report auswählen")

        #Dropdown Auswahlliste
        Reports = [
        "Alle Mitarbeiter",
        "Alle Projekte",
        "Alle Skills"
        ]

        #Widgets
        #Labels & Dropdown
        Lbl_Headline = Label(self.ReportSelection_Win, text = "Bitte wählen Sie einen Report")#Create Label
        Lbl_Headline.grid(column=0, row=0, padx=10, pady=10) #Show Label

        Drop_Reports = ttk.Combobox(self.ReportSelection_Win)
        Drop_Reports.grid(column=0, row=1, padx=10, pady=10)
        Drop_Reports['values'] = Reports

        #Buttons

        Btt_Back_RepSelect = Button(self.ReportSelection_Win, text="Zurück")
        Btt_Back_RepSelect.bind("<Button-1>", self.Func_ReportSelection_Back)#Back to Cockpit
        Btt_Back_RepSelect.grid(column=0, row=2, padx=10, pady=10, sticky=E)

    #Funktionen für Report Fenster    
    def Func_ReportSelection_Back(self, event = None):
        self.ReportSelection_Win.withdraw()
        Cockpit_Win.deiconify()


Cockpit_Win = Tk()
#Modify the Window [◙Not essential for Issue]
Cockpit_Win.title("Ressourcen Verwaltung")
Cockpit_Win.columnconfigure(1, weight=1)



Lbl_Descr_Rep = Label(Cockpit_Win, text = "Report auswählen und ausgeben")#Create Label
Lbl_Descr_Rep.grid(column=0, row=2, padx=10) #Show Label

Btt_Show_Rep = Button(Cockpit_Win, text="Reports", width=35)
Btt_Show_Rep.bind("<Button-1>",Func_Show_Rep)#Button click starts function
Btt_Show_Rep.grid(column=1, row=2, padx=10, pady=7, sticky=E)



Cockpit_Win.geometry('350x170') #Window size


#Make the windows stay (loop)      
Cockpit_Win.mainloop()

说明：我创建了将您的报告写入窗口的类。和隐藏main_window的函数，使Topwindow

打开一个新窗口并返回
