python wxpython application

本文实例讲述了python之wxPython的使用方法,分享给大家供大家参考。具体方法如下:

先来看看效果,这里加载一张图片:

代码如下:

#!/usr/bin/env python 
"""hello wxPython program""" 
 
import wx 
 
class Frame(wx.Frame): #wxPrame subclass 
  """Frame class that display a image""" 
  def __init__(self, image, parent=None, id=-1, 
         pos=wx.DefaultPosition, 
         title="Hello ,wxPython"):  #3 
  #create a Frame instance and display a image 
    temp = image.ConvertToBitmap() 
    size = temp.GetWidth(),temp.GetHeight() 
    wx.Frame.__init__(self,parent,id,title,pos,size) 
    self.bmp = wx.StaticBitmap(parent=self, bitmap=temp) 
    pass 
   
class App(wx.App): #5 wx.App subclass 
  """Application class""" 
   
  def OnInit(self): 
    image = wx.Image('wxPython.jpg',wx.BITMAP_TYPE_JPEG) 
    self.frame = Frame(image) 
     
    self.frame.Show(True) 
    self.SetTopWindow(self.frame) 
    return True 
   
def main(): 
  app = App() 
  app.MainLoop() 
   
if __name__ == "__main__": 
  main() 
Copy after login

总结使用wxPython的4个步骤:

1. 导入wxPython包
2. 子类化应用程序类
3. 定义一个应用程序的初始化方法
4. 创建应用程序类(第2步中创建的子类的)的实例
5. 进入第4步中创建的这个应用程序类实例的主事件循环

注:wxPython.jpg就是这张阿甘同学的图片,要和程序放在同一目录下.

希望本文所述对大家的Python程序设计有所帮助。
