wxpython如何在按钮上设置绑定事件，该按钮在单击其他按钮时启用

Question

它包含一个组合框4个按钮。一旦我从组合框中选择一个条目，它将在单击一个按钮时启用一个按钮，然后启用其余按钮。我想在点击它时启用按钮后发送命令。 以下是我的代码：

import wx
import xlrd
import os,sys,time
folderpath = os.path.dirname(os.path.dirname(os.path.dirname(os.path.realpath(__file__))))
print folderpath
site_lib_path = os.path.join(folderpath, "site_lib")

files = os.listdir(site_lib_path)
for file in files:
    sys.path.append(os.path.join(site_lib_path, file))

                            time.sleep(1)

我想在启用此按钮self.act_button.Enable（True）后发送命令。

您可以在禁用按钮之前将按钮绑定到事件。在启用它们之前，它们不会对事件（除了鼠标事件之外）做出反应。启用按钮时没有理由绑定事件。

如果你想在启用过程之后调用一个函数（即self.act_button.Enable(True)），那么只需在之后调用该函数：

self.act_button.Enable(True) 
self.myFunction(*args, **kwargs)

如果您想创建某种自定义事件，那么您需要了解如何使用wx.PostEvent和wx.lib.newevent。您也可能会对以下资源感兴趣：
