wxPython垂直滚动笔记本标签

Question

我正在尝试使用wxPython为我的一个笔记本标签添加一个垂直滚动条。我试过添加窗口样式wx。VSCROLL到几个不同的面板，我没有得到任何运气。下面是我的代码:

import wx
import os
class MyFrame(wx.Frame):
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title=title, size=(500,200))
        main = wx.Panel(self)
        nb = wx.Notebook(main)
        loginPg = wx.Panel(nb)
        entryPg = wx.Panel(nb, style=wx.VSCROLL) //<--- This kind of works
        projectsPg = wx.Panel(nb)
        nb.AddPage(loginPg, "Login")
        nb.AddPage(entryPg, "Entry")
        nb.AddPage(projectsPg, "Projects")
        self.entTitle = titlePanel(entryPg, -1)
        self.entLabel = labelPanel(entryPg, -1)
        self.entDescription = descrPanel(entryPg, -1)
        mainSizer = wx.BoxSizer(wx.VERTICAL)
        entryPgBox = wx.BoxSizer(wx.VERTICAL)
        mainSizer.Add(nb, 1, wx.ALL|wx.EXPAND)
        entryPgBox.Add(self.entTitle, 0, wx.EXPAND)
        entryPgBox.Add(self.entLabel, 0, wx.EXPAND)
        entryPgBox.Add(self.entDescription, 0, wx.EXPAND)
        entryPg.SetAutoLayout(True)
        entryPg.SetSizer(entryPgBox)
        entryPgBox.Fit(entryPg)
        main.SetAutoLayout(True)
        main.SetSizer(mainSizer)
        mainSizer.Fit(main)
        self.Layout()
        self.Show()
app = wx.App(False)
frame = MyFrame(None, -1, 'Test')
frame.Show()
app.MainLoop()

我的目标是让我的笔记本的第二个标签"条目"垂直可滚动。通过添加style=wx。我得到一个滚动条的选项卡，但它不会向下滚动。如何让我的Notebook Tab entryPg有一个向下滚动的垂直滚动条?任何帮助都非常感谢!

使用wx.ScrolledWindow代替wx.Panel来获得垂直滚动条

下面是一个简单的例子:

import wx
class Frame ( wx.Frame ):
    def __init__( self, parent ):
        wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = u"Test", pos = wx.DefaultPosition, size = wx.Size( 600,300 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )
        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )
        sizer = wx.BoxSizer( wx.VERTICAL )
        self.notebook = wx.Notebook( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, 0 )
        self.login = wx.Panel( self.notebook, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
        self.notebook.AddPage( self.login, u"Login", False )
        self.entry = wx.ScrolledWindow( self.notebook, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.HSCROLL|wx.VSCROLL )
        self.entry.SetScrollRate( 5, 5 )
        entry_sizer = wx.BoxSizer( wx.VERTICAL )
        self.text = wx.StaticText( self.entry, wx.ID_ANY, u"Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim.

Maecenas nec odio et ante tincidunt tempus. Donec vitae sapien ut libero venenatis faucibus. Nullam quis ante. Etiam sit amet orci eget eros faucibus tincidunt. Duis leo. Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna. Sed consequat, leo eget bibendum sodales, augue velit cursus nunc,", wx.DefaultPosition, wx.DefaultSize, 0 )
        self.text.Wrap( 600 )
        entry_sizer.Add( self.text, 1, wx.ALL, 0 )

        self.entry.SetSizer( entry_sizer )
        self.entry.Layout()
        entry_sizer.Fit( self.entry )
        self.notebook.AddPage( self.entry, u"Entry", True )
        sizer.Add( self.notebook, 1, wx.EXPAND |wx.ALL, 0 )

        self.SetSizer( sizer )
        self.Layout()
        self.Centre( wx.BOTH )
        self.Show()
if __name__ == "__main__":
    app = wx.App()
    Frame(None)
    app.MainLoop()

这里的Entry页面将有一个垂直和水平滚动条。注意，只有当小部件的内容超出当前显示的大小时，滚动条才会被激活。如果你最大化这个应用程序窗口，滚动条就会消失。
