尝试在 Tkinter 中使用类来创建多个框架

Trying to use classes in Tkinter to create multiple frames

我正在尝试在我的主要父窗口小部件中创建 2 个框架 - 一个使用 grid() 方法,另一个使用 pack() 方法。我首先以程序的方式编写它,它太混乱了,所以我试图使用类来清理代码。下面是相关代码,我尝试使用 init 方法创建 2 个帧,但它会抛出各种错误。

from tkinter import *

class Application(Frame):
    """This class creates packed frames for the GUI"""
    def __init__(self, master):
        Frame.__init__(self, master)
        self.framepack = Frame(master)
        self.framepack.pack(side=BOTTOM, fill=X)
        self.framegrid = Frame(master)
        self.framegrid.pack(side=TOP)
        self.create_widgets()

    def create_widgets(self):
        #Container 1 using LabelFrame, houses email and password labels and entries
        self.inputlabels1 = LabelFrame(self, self.framepack, text="Input email login information here")
        self.inputlabels1.grid(row=0, column=0, padx=10, pady=10)
        self.emailfield = Label(self.inputlabels1, text="Email Address")     #Labels
        self.passfield = Label(self.inputlabels1, text="Password")

root = Tk()
app = Application(root)
root.mainloop()

整件事都分崩离析了。问题代码是这样的:

        self.inputlabels1 = LabelFrame(self, self.framepack, text="Input email login information here")

我正在尝试将此 Labelframe 小部件放入我之前初始化的两个框架之一 framepack 中,但它会引发错误。我的语法有问题吗?

您正在尝试给 LabelFrame 两个 parent。 parent 应该是 self.framepack。删除第一个参数应该可以解决问题:

self.inputlabels1 = LabelFrame(self.framepack, text="Input email login information here")

我修改了你的例子,让它工作,并显示一些东西。在目前的形式下,它不起作用。另外,我给框架添加了颜色,这样它们就很容易被看到。这有助于组织您的布局,并了解正在发生的事情:

from tkinter import *

class Application(Frame):
    """This class creates packed frames for the GUI"""
    def __init__(self, master):
        Frame.__init__(self, master)

        # added width=180, height=40, background='red'
        self.framepack = Frame(master, width=180, height=40, background='red')
        self.framepack.pack(side=BOTTOM, fill=X)

        # added width=180, height=40, background='green'
        self.framegrid = Frame(master, width=180, height=40, background='green')
        self.framegrid.pack(side=TOP)
        self.create_widgets()

    def create_widgets(self):
        # Container 1 using LabelFrame, houses email and password labels and entries

        # Removed `self,` from the orginal code.
        self.inputlabels1 = LabelFrame(self.framepack, text="Input email login information here")
        self.inputlabels1.grid(row=0, column=0, padx=10, pady=10)        
        self.emailfield = Label(self.inputlabels1, text="Email Address")     #Labels

        # Called pack()
        self.emailfield.pack()
        self.passfield  = Label(self.inputlabels1, text="Password")

        # Called pack()
        self.passfield.pack()

root = Tk()
app = Application(root)
root.mainloop()

希望对您有所帮助。
