的wxPython：问题与例如

Question

我努力学习的wxPython，我也得到一个问题，当我从维基运行示例代码布局：

主框架不调整正确。少了什么东西？

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

     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)

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

Answer 1

啊哈，运行了它。 frame.Fit（）的调用在frame.Show（）之前缺少。

而不是

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

应该

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