Question

我正在尝试在用户选择或更改笔记本上的标签时触发事件。这是我的代码。在PageOne类中，我尝试将wx.aui.EVT_AUINOTEBOOK_PAGE_CHANGED与ChangingTest（self，evt）函数绑定。似乎无论我在绑定时尝试使用什么事件，我都无法触发事件。这可能吗？我错过了什么？

点击按钮并调用self.ChangingTest没问题，但是我想点击选项卡调用self.ChangingTest。

import wx
import wx.lib.inspection

class PageOne(wx.Panel):
   def __init__(self, parent):
       wx.Panel.__init__(self, parent)
       box = wx.BoxSizer(wx.VERTICAL)
       # Want the users' click on the panel tab to fire an event and 
       # call ChangingTest
       self.Bind(wx.aui.EVT_AUINOTEBOOK_PAGE_CHANGED, self.ChangingTest)

       cmdClick = wx.Button(self, wx.ID_CLOSE, "Click Me")
       cmdClick.Bind(wx.EVT_BUTTON, self.ChangingTest)
       box.Add(cmdClick, 0, wx.ALL, 10)


   def ChangingTest(self, evt):
       print "ChangingTest2"


class PageTwo(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is a PageTwo object", (40,40))

class PageThree(wx.Panel):
   def __init__(self, parent):
       wx.Panel.__init__(self, parent)
       t = wx.StaticText(self, -1, "This is a PageThree object", (60,60))


class MainFrame(wx.Frame):
   def __init__(self):
       wx.Frame.__init__(self, None, title="Simple Notebook Example")

       # Here we create a panel and a notebook on the panel
       p = wx.Panel(self)
       nb = wx.Notebook(p)

       # create the page windows as children of the notebook
       page1 = PageOne(nb)
       page2 = PageTwo(nb)
       page3 = PageThree(nb)

       # add the pages to the notebook with the label to show on the tab
       nb.AddPage(page1, "Page 1")
       nb.AddPage(page2, "Page 2")
       nb.AddPage(page3, "Page 3")

       # finally, put the notebook in a sizer for the panel to manage
       # the layout
       sizer = wx.BoxSizer()
       sizer.Add(nb, 1, wx.EXPAND)
       p.SetSizer(sizer)



if __name__ == "__main__":
    app = wx.App()
    MainFrame().Show()
    app.MainLoop()

我的工作版本在这里：

import wx

class PageOne(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is a PageOne object", (20,20))

class PageTwo(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is a PageTwo object", (40,40))

class PageThree(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        t = wx.StaticText(self, -1, "This is a PageThree object", (60,60))


class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title="Simple Notebook Example")

        # Here we create a panel and a notebook on the panel
        p = wx.Panel(self)
        nb = wx.Notebook(p)

        # create the page windows as children of the notebook
        page1 = PageOne(nb)
        page2 = PageTwo(nb)
        page3 = PageThree(nb)

        # add the pages to the notebook with the label to show on the tab
        nb.AddPage(page1, "Page 1")
        nb.AddPage(page2, "Page 2")
        nb.AddPage(page3, "Page 3")

        # finally, put the notebook in a sizer for the panel to manage
        # the layout
        sizer = wx.BoxSizer()
        sizer.Add(nb, 1, wx.EXPAND)
        p.SetSizer(sizer)

    # bind event to notebook
        nb.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.ChangingTest)

    def ChangingTest(self, evt):
       print "It worked!"


if __name__ == "__main__":
    app = wx.App()
    MainFrame().Show()
    app.MainLoop()

使用wx.EVT_NOTEBOOK_PAGE_CHANGED而不是wx.aui.EVT_AUINOTEBOOK_PAGE_CHANGED，因为您使用的是wx.Notebook，而不是wx.aui.AuiNotebook。此外，您应该绑定不是PageOne类而是绑定笔记本对象。所以你可以写parent.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.ChangingTest)或者你可以将它绑定在PageOne类（nb.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, ...)）之外。

在wxPython中选择笔记本中的选项卡时没有任何事件
