如何從子窗口獲取GUI主窗口中的數據？

Question

我想學習Python並試圖建立一個GUI。我面臨的一個問題如下：

在我的代碼中，我試圖從'Ausgewahlte'複選框被選中時從用戶那裏獲得輸入，當選擇打開子窗口並允許用戶輸入數據。現在我必須告訴主GUI從Child窗口獲取數據，或根據'Alle'或'Ausgewahlte'之間的選擇使用默認數據。

首先，我無法使用主GUI中Child窗口中定義的數據。

如果你們中的任何人都能幫上忙，那將會很棒。

感謝您的期待！

Answer 1

如果我得到它的權利...... 對於這種投入（字符串我想）你可以使用

tkSimpleDialog.askstring(title, prompt [,options]) 

要創建一個對話框。該函數返回輸入的字符串。

Answer 2

這是一個從子窗口修改父窗口的示例。

在selected()方法通過self參數將是子窗口的父項。

def selected(self): 
    child_window(self) 

您可以按以下更改child_window：

class child_window(Tkinter.Tk): 

    def __init__(self,parent): 

     #Save parent reference 

     self.parent = parent 
     self.root = Tkinter.Toplevel(parent) 
     label = Tkinter.Label(self.root,text="Bitte geben Sie die Szenarien nummer ein :",anchor="w").grid(column=0,row=0,columnspan=1,sticky='EW') 

     #Create your widget as this, simple to read. 

     self.entry1 = Tkinter.Entry(self.root) 
     self.entry1.grid(column=0,row=1,sticky='EW',padx=10) 

     self.ok_button = Tkinter.Button(self.root,text=u"OK",command=self.closechild).grid(column=1,row=2,pady=10,columnspan=1,sticky='W') 


    def closechild(self): 

     Szenario_all1= self.entry1.get() 

     #self.parent.new_data(Szenario_all1) 

     #To change parent value of entry1 from here 
     #just call insert() method. 

     self.parent.entry1.insert(0, Szenario_all1) 

     #To delete content of self.parent.entry1 use: 
     #self.parent.entry1.delete(0, len(self.parent.entry1.get())) 

     self.root.destroy() 

Answer 3

我會使用的 「Ausgewahlte」 選項另一項。最初，您可以將該條目設置爲禁用，以便無法輸入文本。

self.entry7=Tkinter.Entry(self, state = 'disabled') 

當「Ausgewahlte」複選框被選中，那麼您可以啓用項允許用戶輸入他/她的文字。

self.entry7['state'] = 'normal' 

而且我會避免使用全局變量，你可以只將它們添加到類像這樣：

self.variableName = ... 

所以在最後我會做這樣的事情：

import Tkinter 
import tkSimpleDialog 

class PST_TEG(Tkinter.Tk): 

def __init__(self,parent): 
    Tkinter.Tk.__init__(self,parent) 
    self.parent = parent 
    self.initialize() 

def initialize(self): 

    # Label 
    self.grid() 
    label = Tkinter.Label(self,text="Projekt Root Ordner Name :",anchor="w").grid(column=0,row=0,columnspan=1,sticky='EW') 
    label = Tkinter.Label(self,text="Projekt Name :",anchor="w").grid(column=0,row=1,columnspan=1,sticky='EW') 
    label = Tkinter.Label(self,text="Experiment Name :",anchor="w").grid(column=0,row=2,columnspan=1,sticky='EW')   
    label = Tkinter.Label(self,text="Plattform Name :",anchor="w").grid(column=0,row=3,columnspan=1,sticky='EW') 
    label = Tkinter.Label(self,text="Anzahl der Szenarien :",anchor="w").grid(column=0,row=4,columnspan=1,sticky='EW') 
    label = Tkinter.Label(self,text="Temperatur Kuhlwasser :",anchor="w").grid(column=0,row=5,columnspan=1,sticky='EW') 

    label = Tkinter.Label(self,text="Ausgewahlte :",anchor="w").grid(column=0,row=6,columnspan=1,sticky='EW') 

    label = Tkinter.Label(self,text="Szenarien :",anchor="w").grid(column=0,row=7,columnspan=1,sticky='EW')
