Question

我的复选框C1未显示并导致问题永远不会完成。这里发生了什么？

from Tkinter import *

class LabeledEntry(Frame):
    def __init__(self, parent, *args, **kargs):
        text = kargs.pop("text")
        Frame.__init__(self, parent)
        Label(self, text=text, justify=LEFT).grid(sticky=W, column=0, row=0)
        Entry(self, *args, **kargs).grid(sticky=E, column=1, row=0)

class User_Input:
    def __init__(self, parent, fields):

        GUIFrame = Frame(parent)
        GUIFrame.pack(expand=True, anchor=NW)

        field_index = 1
        for field in fields:
            self.field = LabeledEntry(GUIFrame, text=field)
            self.field.grid(column=0, row=field_index, pady=1)
            self.field.grid_columnconfigure(index = 0, minsize = 150)
            field_index += 1
        CheckVar1 = IntVar()
        self.C1 = Checkbutton(parent, text = "checkbox1", variable = CheckVar1, onvalue = 1, offvalue = 0)
        self.C1.grid(column=2, row=2)


fields = ['Entry Box 1:', 'Entry Box 2']


root = Tk()
MainFrame = User_Input(root, fields)
root.mainloop()

尝试将.grid上的C1来电更改为.pack(anchor = W)。您已经在pack框架上使用了parent（使用GUIFrame），因此Tkinter将很乐意等待您尝试决定使用哪个布局管理器。

from Tkinter import *

class LabeledEntry(Frame):
    def __init__(self, parent, *args, **kargs):
        text = kargs.pop("text")
        Frame.__init__(self, parent)
        Label(self, text=text, justify=LEFT).grid(sticky=W, column=0, row=0)
        Entry(self, *args, **kargs).grid(sticky=E, column=1, row=0)

class User_Input:
    def __init__(self, parent, fields):

        GUIFrame = Frame(parent)
        GUIFrame.pack(expand=True, anchor=NW)

        field_index = 1
        for field in fields:
            self.field = LabeledEntry(GUIFrame, text=field)
            self.field.grid(column=0, row=field_index, pady=1)
            self.field.grid_columnconfigure(index = 0, minsize = 150)
            field_index += 1
        CheckVar1 = IntVar()
        self.C1 = Checkbutton(parent, text = "checkbox1", variable = CheckVar1, onvalue = 1, offvalue = 0)
        self.C1.pack(anchor = W)


fields = ['Entry Box 1:', 'Entry Box 2']


root = Tk()
MainFrame = User_Input(root, fields)
root.mainloop()

尝试使用Frame和root创建它，因此将Array ( [0] => stdClass Object ( [id] => 226 [city] => Dhaka ) [1] => stdClass Object ( [id] => 228 [city] => Charleston County ) [2] => stdClass Object ( [id] => 229 [city] => Dhaka ) [3] => stdClass Object ( [id] => 232 [city] => Dhaka ) [4] => stdClass Object ( [id] => 234 [city] => Miami-Dade County )替换为let client: MSClient = MSClient(applicationURLString: "https://yoururl.azure-mobile.net/", applicationKey: "yourApplicationKey") client.push.registerNativeWithDeviceToken(deviceToken, tags: nil, completion: {(error) -> Void in if error != nil{ NSLog("Error registering for notifications: %@", error) } })

复选框不会出现在使用网格的Tkinter中
