Question

我有下面的代码，使用tkinter创建一个python GUI，它向用户提供了一些选项，如两个复选框和两个填充文本填充。我试图让程序创建一个文件，当用户单击go按钮时，该文件填充模板中的字段。例如，如果客人名称是charles marriott。我正在尝试创建一个名为charles marriott.html的文件，其中包含一个类似＆＃34;欢迎％s的语句到酒店。我们看到你将搭乘飞机前往酒店。＆＃34;我是否必须创建另一个功能来执行此操作，这甚至可以与Tkinter一起使用，还是我需要使用另一个我不知道的库？

from Tkinter import *

    class App:
        def __init__(self, master):
            column0_padx = 24
            row_pady = 36

            #Label 1
            lbl_testcase_exec = Label(master, text="Visiting by Train",
                                      wraplength=100, anchor='w', justify='left')
            lbl_results_cmp = Label(master, text="Visting by Plane",
                                    wraplength=100, justify='left')
            testcase_exec = Checkbutton(master)
            results_cmp = Checkbutton(master)
            tolerance = Entry(master, width=4)
            lbl_analysis = Label(master, text="Guest Name")
            analysis_lib = Entry(master, width=30)

            lbl_testcase_exec.grid(row=0, column=2, padx=20, pady=12, sticky='w')
            lbl_results_cmp.grid(row=0, column=3, pady=12, sticky='w')
            lbl_analysis.grid(row=1, column=0, sticky='w', padx=column0_padx)
            analysis_lib.grid(row=1, column=1, sticky='w')
            testcase_exec.grid(row=1, column=2, padx=20, sticky='w')
            results_cmp.grid(row=1, column=3, sticky='w')
            tolerance.grid(row=1, column=4, padx=20, sticky='w')

            #Label 2
            lbl_ref_analysis = Label(
                master, text="Point of Contact",
                wraplength=150, justify='left', pady=row_pady)
            ref_analysis_lib = Entry(master, width=30)
            lbl_ref_analysis.grid(row=2, column=0, sticky='w', padx=column0_padx)
            ref_analysis_lib.grid(row=2, column=1, sticky='w')

            # buttons
            bottom_frame = Frame(master)
            bottom_frame.grid(row=5, column=1, columnspan=3, sticky='w')

            btn_start = Button(bottom_frame, text = "Go", width=7)
            btn_start.pack(side='left')
            btn_commit = Button(bottom_frame, text="Commit", width=7)
            btn_commit.pack(side='left', padx=80)
            btn_exit = Button(bottom_frame, text="Exit", width=7)
            btn_exit.pack(side='left')

    root = Tk()
    root.title("Templates")
    root.minsize(800, 400)
    app = App(root)
    root.mainloop()

向创建文件的class App添加另一种方法，然后通过使用command=self.newmethod配置按钮将其与按钮关联相关联。

以下是基于您的代码的最小示例：

from Tkinter import *

class App:
    def __init__(self, master):
        column0_padx = 24
        row_pady = 36

        #Label 1
        lbl_testcase_exec = Label(master, text="Visiting by Train",
                                  wraplength=100, anchor='w', justify='left')
        lbl_results_cmp = Label(master, text="Visting by Plane",
                                wraplength=100, justify='left')
        testcase_exec = Checkbutton(master)
        results_cmp = Checkbutton(master)
        tolerance = Entry(master, width=4)
        lbl_analysis = Label(master, text="Guest Name")
        analysis_lib = Entry(master, width=30)

        lbl_testcase_exec.grid(row=0, column=2, padx=20, pady=12, sticky='w')
        lbl_results_cmp.grid(row=0, column=3, pady=12, sticky='w')
        lbl_analysis.grid(row=1, column=0, sticky='w', padx=column0_padx)
        analysis_lib.grid(row=1, column=1, sticky='w')
        testcase_exec.grid(row=1, column=2, padx=20, sticky='w')
        results_cmp.grid(row=1, column=3, sticky='w')
        tolerance.grid(row=1, column=4, padx=20, sticky='w')

        #Label 2
        lbl_ref_analysis = Label(
            master, text="Point of Contact",
            wraplength=150, justify='left', pady=row_pady)
        ref_analysis_lib = Entry(master, width=30)
        lbl_ref_analysis.grid(row=2, column=0, sticky='w', padx=column0_padx)
        ref_analysis_lib.grid(row=2, column=1, sticky='w')

        # buttons
        bottom_frame = Frame(master)
        bottom_frame.grid(row=5, column=1, columnspan=3, sticky='w')

        btn_start = Button(bottom_frame, text = "Go", width=7)
        btn_start.pack(side='left')
        btn_commit = Button(bottom_frame, text="Commit", width=7,
                            command=self.write_file)  # added command=
        btn_commit.pack(side='left', padx=80)
        btn_exit = Button(bottom_frame, text="Exit", width=7)
        btn_exit.pack(side='left')

    # additional method
    def write_file(self):
        """ Write data to file. """
        with open(filename, 'wt') as outf:
            outf.write(...whatever...)
            outf.write(...whatever else...)
               ...

root = Tk()
root.title("Templates")
root.minsize(800, 400)
app = App(root)
root.mainloop()

使用tkinter按钮命令将数据写入文件
