将可执行代码添加到我的 wxpython gui 文本框

Question

我目前有一个工作脚本，可让我创建备份文件的副本，获取该副本并将其重命名为 Filename_New，并将原始文件重命名为 Filename_Bad。

我是创建 GUI 和一般 python 代码的新手，但目前有一个 gui，并希望将 3 段特定代码绑定到 gui 中的不同框，以便在步骤 1 中输入文件名时在 gui 它运行我的 python 代码的那部分。

不太确定如何将这两个东西整合在一起，所以任何建议都将不胜感激。在此先感谢，希望下面的代码格式正确。

这是我执行复制过程的一段python代码。

我有两个其他变体，将 _NEW 和 _BAD 添加到其他文件。

我想将此代码绑定到该 GUI 中的文本框中，您可以在其中输入文件名并在您点击 Okay 时执行代码。

### 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)

    def InitUI(self):

        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)

        self.tc = wx.TextCtrl(panel)
        sizer.Add(self.tc, pos=(1, 0), span=(1, 2),

            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，然后在该文件名上执行代码。

欢迎来到 StackOverflow。

对您的问题的简短回答是，您需要将 GUI 中的按钮Bind 使用某种方法。您可以在下面的代码中看到这是如何完成的。

我稍微更改了您的代码，因为您定义了 wx.BoxSixer，但随后您将小部件添加到 wx.GridBagSizer。此外，我更改了按钮以向您展示如何搜索带有wx.FileDialog 的文件，以防您不想输入文件的路径并且因为我假设（可能不正确）关闭按钮将关闭应用程序。无需这样做，只需单击 X 即可关闭应用程序。
