wxpython之dialog学习

[这段时间一直在学wxpython，但一直以读代码为主，总感觉不写点，无法进步，所以就在这开一个写wxpython代码的头，以资鼓励...]

这篇其实比较简单，就是一个带有按钮的窗口，但点击这个按钮后提示一个对话框。
import wx

class SubclassDialog(wx.Dialog):
    def __init__(self):
        wx.Dialog.__init__(self, None, -1, 'Dialog',
                pos=(200,200),size=(300, 100))
        okButton = wx.Button(self, wx.ID_OK, "OK", pos=(15, 15))
        okButton.SetDefault()
        cancelButton = wx.Button(self, wx.ID_CANCEL, "Cancel",
                pos=(115, 15))

class TestFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self,None,-1,'Study dialog of wxpython')
        panel=wx.Panel(self,-1)
        button=wx.Button(panel,-1,"Open dialog!",pos=(150,70),size=(100,50),style=wx.BU_EXACTFIT)
        button.Bind(wx.EVT_BUTTON,self.OnOpenDialog)
   
    def OnOpenDialog(self,evt):
        dialog = SubclassDialog()
        result = dialog.ShowModal()
        if result == wx.ID_OK:
            print "OK"
        else:
            print "Cancel"
        dialog.Destroy()
       
if __name__=='__main__':
    app=wx.PySimpleApp()
    frame=TestFrame()
    frame.Show()
    app.MainLoop()
