我的问题是:
NotebookCtrl下载附带的示例本身添加和删除页面非常好。我快要完全放弃这个项目了。下面是代码的样子(请注意,这是应用程序的一小部分,但它涵盖了wxPython的内容)
class Chatroom(Panel):
''' Frame for the notebook widget to tabulate a chatroom'''
def __init__(self, ns, parent):
Panel.__init__(self, parent, -1)
self.msgs, self.typed, self.pcbuff = [], [], {}

self.Privclasses = TreeCtrl(self, size=(150, -1))
self.Buffer = wx.html.HtmlWindow(self)
self.Buffer.SetStandardFonts(8)
self.templbl = StaticText(self, -1, 'This is where the formatting buttons will go!')
# note to remember: self.templbl.SetLabel('string') sets the label
self.Typer = TextCtrl(self, size=(-1, 50), style=wx.TE_MULTILINE)

self.switchtab(bot, self.chatorder[-1])
x = self.tabids_reverse[ns]
del self.tabids_reverse[ns], self.tabids[x], self.channels[ns]
Chatroom类涵盖了每个选项卡中应该包含的内容。类应用程序中添加的第一个选项卡
初始化
这个功能非常好,甚至可以打印聊天服务在尝试连接时收到的消息。一旦服务向我发送了一个join数据包,它就会调用与添加该选项卡相同的函数AddChatroom(),并且应该创建完全相同的内容,只打印专门用于该聊天室的消息。它创建了选项卡,但是聊天室页面完全是空的和灰色的。我很难过:C
如果你能帮助我,请提前谢谢。
我已经为这个脚本编写了一个工作示例,您可以自己运行(如果您有wxPython的话)。它使用普通的笔记本而不是NotebookCtrl,所以你不必下载这个小部件,但是这两个小部件都会出现错误。该示例设置窗口,并在进入mainloop之前设置主调试选项卡和聊天室选项卡。在mainloop之后,任何添加了后缀的聊天室都是完全空白的
