wxPython和PyQt的Hello World例子比较
wxPython和PyQt分别是wxWidgets和Qt的python绑定，wxWidgets和Qt都是跨平台的GUI库，不过前者是开源免费的，而后者是基于商业License让我们分别看看wxPython和PyQt的Hello World程序
wxPython
首先去http://www.python.org下载Windows下的python2.5，然后去http://www.wxpython.org下载相应的Windows安装包
装好后写个hellowx.py看看效果:
import wxclass MyFrame(wx.Frame): def __init__(self, parent, title): wx.Frame.__init__(self, parent, -1, title, pos=(150, 150), size=(350, 200)) menuBar = wx.MenuBar() self.SetMenuBar(menuBar) menu = wx.Menu() menu.Append(wx.ID_EXIT, "E&xit", "Exit this application") self.Bind(wx.EVT_MENU, self.OnTimeToClose, id=wx.ID_EXIT) menuBar.Append(menu, "&File") panel = wx.Panel(self) text = wx.StaticText(panel, -1, "Hello wxPython!") text.SetFont(wx.Font(12, wx.SWISS, wx.NORMAL, wx.BOLD)) text.SetSize(text.GetBestSize()) panel.Layout() def OnTimeToClose(self, evt): self.Close()class MyApp(wx.App): def OnInit(self): frame = MyFrame(None, "Hello wxPython!") self.SetTopWindow(frame) frame.Show(True) return True app = MyApp()app.MainLoop()
App->Frame->MenuBar/Panel，结构很清晰
PyQt
去http://www.quadgames.com/download/pythonqt/下载Windows的PyQt安装包，PyQtGPL10.exe目前只支持到Python2.4
然后写个helloqt.py看看效果:
import sysfrom qt import *class HelloButton(QPushButton): def __init__(self, *args): QPushButton.__init__(self, *args) self.setText("Hello World")class HelloWindow(QMainWindow): def __init__(self, *args): QMainWindow.__init__(self, *args) self.button = HelloButton(self) self.setCentralWidget(self.button)def main(args): app = QApplication(args) win = HelloWindow() win.show() app.connect(app, SIGNAL("lastWindowClosed()"), app, SLOT("quit()")) app.exec_loop()if __name__ == "__main__": main(sys.argv)
也是App->Window->MenuBar的模式，同wx没多大区别
体验
总体觉得Qt的类名起的有点怪异，wxPython看起来很优美
