wxPython笔记本标签垂直滚动

Question

我想使用wxPython将垂直滚动条添加到我的笔记本标签之一。我曾尝试将窗口样式wx.VSCROLL添加到几个不同的面板，但我没有得到任何好运。这里是我的代码：

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选项卡“条目”垂直滚动。通过将style = wx.VSCROLL添加到entryPg，我得到该选项卡的滚动条，但它不会向下滚动。我如何让我的笔记本标签entryPg有一个垂直滚动条向下滚动？ 任何帮助，非常感谢！

使用wx.ScrolledWindow而不是wx.Panel来获得垂直滚动条。

这里有一个小例子：

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Entry页面将同时拥有垂直和水平滚动条。请注意，只有当小部件的内容溢出当前显示的大小时，滚动条才会处于活动状态。如果您最大化该应用程序窗口，sccrollbars将消失。
