一个框架内的小部件未扩展到Tkinter中另一个框架内的全长

Question

有一种情况，在这种情况下，我试图将两个按钮放置在一个框架中，然后将该框架放置在特定行中的另一个框架中。 但是放置在子框架内的按钮没有扩展到全长，如下面的快照所示。

我尝试使用网格，放置等，但仍然无法正常工作。 我在填充或填充等方面并没有尝试太多，也没有设置按钮的默认大小。

试图检查一些解决方案，他们一直说您需要对根小部件进行行配置和列配置等，但是即使这样也不起作用。 有什么建议可以确保小部件扩展到全长吗？

下面是我尝试的代码：对于框架和按钮。

#!/usr/intel/bin/python2.7

        self.ib_frame = None
        self.rb =  None
        self.eb = None

        if not (self.rel3):
            self.rel3 = Label(root, font=MyFontH2, text="What Type Of Widget You Wanted To Create: ")
            self.rel3.grid(row=6, column=0, sticky='W', padx=38)
            self.rel3.rowconfigure(6,weight=1)
        else:
            self.rel3.grid()

        # Frame Code
        if not (self.ib_frame):   
            self.ib_frame = Frame(root)
            self.ib_frame.grid(row=7, column=0, columnspan=1, sticky='WE')
            self.ib_frame.rowconfigure(7,weight=1)
            #self.ib_frame.columnconfigure(0,weight=1)

        # Button1 Code
        if not self.rb: 
            self.rb = Button(self.ib_frame, background="royalblue1", activebackground="blue2", text="RTMM")    
            self.rb.grid(row=0, column=0, sticky='WE')
            self.rb.rowconfigure(0, weight=1)
            # self.rb.pack(side=LEFT, fill=BOTH)

        # Button2 Code
        if not (self.eb):     
            self.eb = Button(self.ib_frame, background="orangered", activebackground="orangered3", text="ECG")
            self.eb.grid(row=0, column=1, sticky='WE')
            self.eb.rowconfigure(0, weight=1)
            #self.eb.pack(side=RIGHT, fill=BOTH) 

root = Tk()
root.title("Test UI")

MyFontH2 = tkFont.Font(family='courier', size=20, weight=tkFont.BOLD)

myapp = MyApp(root)
root.mainloop()

输出示例：当我将两个按钮添加到单独的框架中，然后将其放置在根框架的行中时，它们位于右上角。

新更新：我尝试下面的代码，但问题仍然相同。 难道我做错了什么 ？

更新：已修复。 它的columnspan。

您可以使用columnconfigure扩展框架ib_frame的列：

# Frame Code
if not (self.ib_frame):   
    self.ib_frame = Frame(root, bg='tan')
    self.ib_frame.grid(row=7, column=0, columnspan=1, sticky='WE')
    self.ib_frame.rowconfigure(7, weight=1)
    self.ib_frame.columnconfigure([0,1], weight=1)
    #                               ^
    #                      expand both columns
