python - 如何在 Tkinter/TTK 中稍微移动标签中的文本？

Question

我有名字、姓氏和许可证标签。在我的程序中，我希望它们向左对齐，但我希望它们与下面的输入框齐平。目前，它们向左移动了一点。我运气不太好，只能把它们移动一点点。有什么建议吗？

import tkinter
from tkinter import ttk
from tkinter import messagebox


class Adder(ttk.Frame):
    """The adders gui and functions."""
    def __init__(self, parent, *args, **kwargs):
        ttk.Frame.__init__(self, parent, *args, **kwargs)
        self.root = parent
        self.init_gui()

    def on_help(self):
       answer = messagebox.showinfo("Stuff goes here.")

    def on_quit(self):
        """Exits program."""
        root.quit()


    def calculate(self):
        if len(self.lic_entry.get()) == 0:
            self.output['text'] = "Output will go here.\nThis is a test."



    def init_gui(self):
        """Builds GUI."""
        self.root.title('Verify')
        self.root.option_add('*tearOff', 'FALSE')

        self.grid(column=0, row=0, sticky='nsew') # this starts the entire form

        self.menubar = tkinter.Menu(self.root)

        # Input Boxes and Button

        self.first_entry = tkinter.Entry(self, width=28) # first input box
        self.first_entry.grid(sticky='e', column=0, row=2) 

        self.last_entry = tkinter.Entry(self, width=28) # second input box
        self.last_entry.grid(sticky='e', column=1, row=2) 

        self.lic_entry = tkinter.Entry(self, width=28) # third input box
        self.lic_entry.grid(sticky='e', column=2, row=2) 

        self.framespace = tkinter.Frame(self, height=10, width=600) # provides spacing between input boxes and button
        self.framespace.grid(column=0, row=4, columnspan=5)

        self.calc_button = ttk.Button(self, text='Search', command=self.calculate) # button
        self.calc_button.grid(column=0, row=5, columnspan=1, sticky='w')

        # Output frame for answers

        self.output = tkinter.LabelFrame(self, height=200, width=600, bg='#F7F7F7', text=' ', bd=0, labelanchor='n')
        self.output.grid(column=0, row=6, columnspan=5)

        for child in self.winfo_children():  # padx 10 adds horizontal padding on the out edge of window
            child.grid_configure(padx=0, pady=0)

if __name__ == '__main__':
    root = tkinter.Tk()
    Adder(root)
    root.resizable(width=False, height=False) # locks window from being resized
    root.mainloop()

您可以使用标签的 padding 选项在小部件的边框内添加内边距。

来自文档:

Specifies the amount of extra space to allocate for the widget. The padding is a list of up to four length specifications left top right bottom. If fewer than four elements are specified, bottom defaults to top, right defaults to left, and top defaults to left.

例如:

self.last = ttk.Label(..., padding=(2,0,0,0))

当你调用grid时，你可以使用padx:

self.last.grid(..., padx=20)

但是，最后一个似乎不会产生影响，因为稍后在代码中您将 padx 和 pady 值重置为零。您需要删除 padx 的代码才能在此处生效。
