如何将 wx.simplebook 的页面选择绑定到外部按钮？

Question

我正在尝试将 simplebook 的 .ChangeSelection() 函数绑定到不在书中但在同一框架中的按钮。

当前形式的示例代码是一个简单的框架，左侧有页面按钮，右侧显示书籍本身。目前 LHS 按钮未绑定，RHS wx.simplebook 显示空白页“0”。

我想让按钮在按下时显示相应的页面，但我很难在网上找到合适的示例 simplebooks 来学习这种格式。

import wx
### SIMPLEBOOK TEST
class MainPage (wx.Frame):
    def __init__ (self,parent):
        wx.Frame.__init__ ( self, None, 1, title = "NOTEBOOK", pos= wx.DefaultPosition, size = wx.Size( 320,400 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL)
        mainSizer = wx.BoxSizer(wx.HORIZONTAL)
        buttonSizer = wx.BoxSizer(wx.VERTICAL)
        pagesSizer = wx.BoxSizer(wx.VERTICAL)
        mainSizer.Add(buttonSizer,1,wx.EXPAND,0)
        mainSizer.Add(pagesSizer,1,wx.EXPAND,0)
        page1Button = wx.Button(self,wx.ID_ANY,"Page 1",wx.DefaultPosition,wx.DefaultSize,0)
        page2Button = wx.Button(self,wx.ID_ANY,"Page 2",wx.DefaultPosition,wx.DefaultSize,0)
        buttonSizer.Add(page1Button,1,wx.ALL|wx.EXPAND,0)
        buttonSizer.Add(page2Button,1,wx.ALL|wx.EXPAND,0)
        book = BookTest(self)
        pagesSizer.Add(book,1,wx.EXPAND|wx.ALL,2)
        self.SetSizer(mainSizer)
        self.Layout()

        t=wx.StaticText(self,-1,"THIS IS PAGE 1")
        sizer.Add(t,1,wx.EXPAND,0)
        self.Show()

你们真的很亲密。只遗漏了两个细节。

1- 您通过在 class MainPage 中创建的 class 的实例从 class BookTest 调用方法 page1sel。这意味着像这样绑定：

page1Button.Bind(wx.EVT_BUTTON,book.page1sel)

2- 方法 page1sel 需要从 Bind 接收 event。所以必须定义为：

def page1sel(self, event):

page2sel也是一样，（在我看来）应该是class BookTest的方法。

代码：

        mainSizer = wx.BoxSizer(wx.HORIZONTAL)

        pagesSizer = wx.BoxSizer(wx.VERTICAL)
