的wxPython：問題與例如

Question

我努力學習的wxPython，我也得到一個問題，當我從維基運行示例代碼佈局：

主框架不調整正確。少了什麼東西？

我下Enthought Python發行7.3-2（Python的2.7.3）

import wx 
class ExamplePanel(wx.Panel): 
    def __init__(self, parent): 
     wx.Panel.__init__(self, parent) 

     # create some sizers 
     mainSizer = wx.BoxSizer(wx.VERTICAL) 
     grid = wx.GridBagSizer(hgap=5, vgap=5) 
     hSizer = wx.BoxSizer(wx.HORIZONTAL) 

     self.quote = wx.StaticText(self, label="Your quote: ") 
     grid.Add(self.quote, pos=(0,0)) 

     # A multiline TextCtrl - This is here to show how the events work in this program, don't pay too much attention to it 
     self.logger = wx.TextCtrl(self, size=(200,300), style=wx.TE_MULTILINE | wx.TE_READONLY) 

     # A button 
     self.button =wx.Button(self, label="Save") 
     self.Bind(wx.EVT_BUTTON, self.OnClick,self.button) 

     # the edit control - one line version.

     grid.Add(rb, pos=(5,0), span=(1,2))

app = wx.App(False) 
frame = wx.Frame(None) 
panel = ExamplePanel(frame) 
frame.Show() 
app.MainLoop() 

Answer 1

啊哈，運行了它。 frame.Fit（）的調用在frame.Show（）之前缺少。

而不是

app = wx.App(False) 
frame = wx.Frame(None) 
panel = ExamplePanel(frame) 
frame.Show() 
app.MainLoop() 

應該

app = wx.App(False) 
frame = wx.Frame(None) 
panel = ExamplePanel(frame) 
frame.Fit() 
frame.Show() 
app.MainLoop()
