wxpython中的ScrolledPanel如何不以這種方式工作？

Question

我不知道爲什麼下面的代碼不能正常工作，請大家幫我出：

import wx 
import wx.lib.scrolledpanel as scrolled 

class TaskFrame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(self, parent = None, id = -1, title="ScrolledPanel", size = (500, 600)) 
     MainPanel = wx.Panel(self) 
     NewPanel = scrolled.ScrolledPanel(parent = MainPanel, pos = (100, 100), size = (300, 200), id = -1, style = wx.TAB_TRAVERSAL|wx.SUNKEN_BORDER, name="panel") 

     self.Button = wx.Button(parent = NewPanel, id = -1, label="Log", pos=(500, 30), size=(50, 20)) 
     NewPanel.SetupScrolling() 


class TaskApp(wx.App): 
    def OnInit(self): 
     self.frame = TaskFrame() 
     self.frame.Show() 
     self.SetTopWindow(self.frame) 
     return True 

def main(): 
    App = TaskApp(redirect = False) 
    App.MainLoop() 

if __name__ == "__main__": 
    main() 

日誌按鈕應該在NewPanel和NewPanel應該可以滾動，但它不是，有什麼問題？

嘗試使用sizer。你必須放置一個大於ScrolledPanel的對象來激活滾動（據我所知），所以這應該做我認爲你想要做的事情：

class TaskFrame(wx.Frame): 
    def __init__(self): 
     wx.Frame.__init__(self, parent = None, id = -1, title="ScrolledPanel", size = (500, 600)) 
     MainPanel = wx.Panel(self) 
     NewPanel = scrolled.ScrolledPanel(parent = MainPanel, pos = (100, 100), size = (300, 200), id = -1, style = wx.TAB_TRAVERSAL|wx.SUNKEN_BORDER, name="panel") 

     PanelSizer = wx.BoxSizer() 
     InsidePanel = wx.Panel(NewPanel) 
     self.Button = wx.Button(parent=InsidePanel, id = -1, label="Log", pos=(500, 30), size=(50, 20)) 
     PanelSizer.Add(InsidePanel, proportion=1) 

     NewPanel.SetSizer(PanelSizer) 
     NewPanel.SetupScrolling()
