wxPython的简介

wxPython是Phoenix项目！Phoenix是改进的下一代wxPython，“比以前更好、更强、更快”。这个新的实现主要关注于提高速度、可维护性和可扩展性。就像“经典”的WXPython一样，菲尼克斯封装了WxWistGe+C++工具包，并提供了对WxWistGeAPI API的用户界面部分的访问，使Python应用程序在Windows、MACS或UNIX系统上具有本地GUI，具有本地的外观和感觉，并且需要非常少的（如果有的话）特定于平台的代码。
           实用工具wxdocs和wxdemo将使用wxget（如果必要）下载适当的文件，解压缩它们（如果必要），并启动相应项的适当版本。（文档在默认浏览器中启动，演示用python启动）。
          wxPython是Python语言的跨平台GUI工具箱。使用wxPython，软件开发人员可以为他们的Python应用程序创建真正的本地用户界面，这些应用程序在Windows、Mac和Linux或其他类unix系统上很少或没有修改的情况下运行。

wxPython的安装

pip install wxPython

wxPython的使用方法

wx.Frame.SetBackgroundColour(self,'green')  #给窗口设置背景颜色

1、example 一

# First things, first. Import the wxPython package.
import wx

# Next, create an application object.
app = wx.App()

# Then a frame.
frm = wx.Frame(None, title="Hello World")

# Show it.
frm.Show()

# Start the event loop.
app.MainLoop()

2、example 二

#!/bin/python
"""
Hello World, but with more meat.
"""

import wx

class HelloFrame(wx.Frame):
    """
    A Frame that says Hello World
    """

    def __init__(self, *args, **kw):
        # ensure the parent's __init__ is called
        super(HelloFrame, self).__init__(*args, **kw)

        # create a panel in the frame
        pnl = wx.Panel(self)

        # and put some text with a larger bold font on it
        st = wx.StaticText(pnl, label="Hello World!", pos=(25,25))
        font = st.GetFont()
        font.PointSize += 10
        font = font.Bold()
        st.SetFont(font)

        # create a menu bar
        self.makeMenuBar()

        # and a status bar
        self.CreateStatusBar()
        self.SetStatusText("Welcome to wxPython!")

    def makeMenuBar(self):
        """
        A menu bar is composed of menus, which are composed of menu items.

        helloItem = fileMenu.Append(-1, "&Hello...\tCtrl-H",
                "Help string shown in status bar for this menu item")
        fileMenu.AppendSeparator()

        # label
        exitItem = fileMenu.Append(wx.ID_EXIT)

        # Now a help menu for the about item
        helpMenu = wx.Menu()

        # that the next letter is the "mnemonic" for the menu item. On the
        # platforms that support it those letters are underlined and can be
        # triggered from the keyboard.

        menuBar.Append(fileMenu, "&File")
        menuBar.Append(helpMenu, "&Help")

        # Give the menu bar to the frame
        self.SetMenuBar(menuBar)

        # Finally, associate a handler function with the EVT_MENU event for
        # each of the menu items. That means that when that menu item is
        # activated then the associated handler function will be called.
        self.Bind(wx.EVT_MENU, self.OnHello, helloItem)
        self.Bind(wx.EVT_MENU, self.OnExit,  exitItem)
        self.Bind(wx.EVT_MENU, self.OnAbout, aboutItem)

    def OnExit(self, event):
        """Close the frame, terminating the application."""
        self.Close(True)

    def OnHello(self, event):
        """Say hello to the user."""
        wx.MessageBox("Hello again from wxPython")

    def OnAbout(self, event):
        """Display an About Dialog"""
        wx.MessageBox("This is a wxPython Hello World sample",
                      "About Hello World 2",
                      wx.OK|wx.ICON_INFORMATION)

if __name__ == '__main__':
    # When this module is run (not imported) then create the app, the
    # frame, show it, and start the event loop.
    app = wx.App()
    frm = HelloFrame(None, title='Hello World 2')
    frm.Show()
    app.MainLoop()
