将可执行代码添加到我的wxpython gui文本框中

Question

我目前有一个工作脚本，该脚本可让我创建备份文件的副本，将其复制并重命名为Filename_New，然后将原始文件重命名为Filename_Bad。

我是创建GUI和python代码的新手，但是目前具有gui，并且想将3个特定的代码段绑定到gui中的不同框中，以便在步骤1中输入文件名时在gui中，它将运行我的python代码的这一部分。

不太确定如何将这两件事集成在一起，因此任何建议都将不胜感激。预先感谢，希望下面的代码格式正确。

这是我执行复制过程的一部分python代码。

在上述过程中，我还有其他两种变体，它们将_NEW和_BAD添加到其他文件中。

我想将此代码绑定到该GUI的文本框中，在其中输入文件名，并在单击“确定”时执行该代码。

### Do all your imports as needed

import wx, wx.lib.newevent

import os, sys, copy, shutil

class Example(wx.Frame):
    def __init__(self, parent, title):
        super(Example, self).__init__(parent, title=title)

        self.Centre()

    def InitUI(self):

        panel = wx.Panel(self)
        font = wx.SystemSettings.GetFont(wx.SYS_SYSTEM_FONT)
        font.SetPointSize(9)
        #### As already mentioned you defined a wx.BoxSizer but later were using
        #### a wx.GridBagSizer. By the way I also changed a little bit the span
        #### and flags of the widgets when added to the wx.GridBagSizer
        sizer = wx.GridBagSizer(1, 1)

        text = wx.StaticText(panel, label="Enter the VR File That Crashed: ")
        sizer.Add(text, pos=(0, 0), span=(1, 2), flag=wx.EXPAND|wx.TOP|wx.LEFT|wx.BOTTOM, border=5)

        #### tc will be used by other methods so it is better to use self.tc
        self.tc = wx.TextCtrl(panel)
        sizer.Add(self.tc, pos=(1, 0), span=(1, 2),
            flag=wx.EXPAND|wx.LEFT|wx.RIGHT, border=5)

        #### This is how you Bind the button to a method so everytime the button

        buttonOk.Bind(wx.EVT_BUTTON, self.SearchFile)

            self.tc.SetValue(dlg.GetPath())
        else:

        def rename_copy(oldvr):
            newvrb = os.path.splitext(oldvr)[0] + "_NEW"
            shutil.copy(oldvr, newvrb + ".vr")

        oldvrb = self.tc.GetValue()
        copy_vrb(oldvr)
        file_rename(oldvr)
        rename_copy(oldvr)

        print(oldvr)


if __name__ == '__main__':
    app = wx.App()
    ex = Example(None, title='Rename')
    ex.Show()
    app.MainLoop()
else:
    pass

在gui中输入文件名，并在该文件名上执行代码。

欢迎使用StackOverflow。

这个问题的简短答案是，您需要将GUI中的按钮Bind设为某种方法。您可以在下面的代码中看到如何完成此操作。

我稍稍更改了代码，因为您正在定义wx.BoxSixer，但是随后您将小部件添加到wx.GridBagSizer。另外，我更改了按钮以向您展示如何使用wx.FileDialog搜索文件，以防万一您不想键入文件的路径，并且因为我假设（也许是错误地）关闭按钮是关闭应用程序。无需此操作，只需单击X即可关闭应用程序。
