窗口
在wx.Python中应用wx.Frame类示意窗口。窗口是一个蕴含多个组件的矩形区域，窗口是程序运行后的容器。
Frame窗口
1#!/usr/bin/python 2# -*- coding: UTF-8 -*- 3 4import wx 5 6class MyFrame(wx.Frame): 7 def __init__(self): 8 wx.Frame.__init__(self, None, -1, u'自定义窗口', size=(300, 100)) # 调用父类的初始化办法 910if __name__ == '__main__':11 app = wx.PySimpleApp()12 myFrame = MyFrame()13 myFrame.Show()14 app.MainLoop()成果：
带工具栏和状态栏的Frame窗口
一个残缺的应用程序窗口通常蕴含菜单、工具栏、状态栏等因素。
1#!/usr/bin/python 2# -*- coding: UTF-8 -*- 3 4import wx 5 6class MyFrame(wx.Frame): 7 def __init__(self): 8 wx.Frame.__init__(self, None, -1, u'自定义窗口', size=(300, 200)) 9 png_save = wx.Image('./icons/save_page.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()10 png_home = wx.Image('./icons/go_home.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()11 png_cfg = wx.Image('./icons/settings.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()12 png_forward = wx.Image('./icons/go_forward.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()13 png_back = wx.Image('./icons/go_back.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap()14 toolbar = self.CreateToolBar(wx.TB_HORIZONTAL | wx.TB_TEXT) # 创立工具栏15 toolbar.AddSimpleTool(100, png_save, "Save page")16 toolbar.AddSimpleTool(200, png_home, "Go home")17 toolbar.AddSimpleTool(220, png_back, "Go back")18 toolbar.AddSimpleTool(230, png_forward, "Go Forward")19 toolbar.AddSimpleTool(400, png_cfg, "Settings")20 toolbar.Realize()21 self.CreateStatusBar() # 创立状态栏2223if __name__ == '__main__':24 app = wx.PySimpleApp()25 myFrame = MyFrame()26 myFrame.Show()27 app.MainLoop()成果：
MDI窗口
给MDI窗口增加菜单，并可能在MDI窗口中创立子窗口
1#!/usr/bin/python 2# -*- coding: UTF-8 -*- 3 4import wx 5 6class MDIFrame(wx.MDIParentFrame): 7 def __init__(self): 8 wx.MDIParentFrame.__init__(self, None, -1, u"MDI窗口", size=(300, 200)) 9 menubar = wx.MenuBar() # 增加菜单栏10 menu = wx.Menu() # 增加菜单11 menu.Append(5000, u"新建(&N)") # 增加子菜单12 menu.Append(5001, u"退出(&X)")13 menubar.Append(menu, u"文件(&F)")14 self.Bind(wx.EVT_MENU, self.OnNewWindow, id=5000) # 绑定菜单项的事件15 self.Bind(wx.EVT_MENU, self.OnExit, id=5001)16 self.SetMenuBar(menubar)1718 def OnExit(self, evt):19 self.Close(True)2021 def OnNewWindow(self, evt):22 win = wx.MDIChildFrame(self, -1, u"子窗口") # 新建子窗口23 win.Show(True)2425if __name__ == '__main__':26 app = wx.PySimpleApp()27 frame = MDIFrame()28 frame.Show()29 app.MainLoop()成果：
MiniFrame窗口
1#!/usr/bin/python 2# -*- coding: UTF-8 -*- 3 4import wx 5 6class MiniFrame(wx.MiniFrame): 7 def __init__(self): 8 wx.MiniFrame.__init__(self, None, -1, u'不能最小化和最大化的窗口', pos=(100, 100), size=(300, 200), 9 style=wx.DEFAULT_FRAME_STYLE | wx.CLOSE_BOX)10 # 或者sytel = wx.DEFAULT_FRAME_STYLE ^ (wx.MINIMIZE_BOX | wx.MAXIMIZE_BOX))11 panel = wx.Panel(self, -1, size=(300, 200))1213if __name__ == '__main__':14 app = wx.PySimpleApp()15 frame = MiniFrame()16 frame.Show()17 app.MainLoop()对话框
在wx.Python中对话框都继承自wx.Dialog类。
对话框的创立
1#!/usr/bin/python 2# -*- coding: UTF-8 -*- 3 4import wx 5 6class MyFrame(wx.Frame): 7 def __init__(self): 8 wx.Frame.__init__(self, None, -1, u"自定义对话框", size=(300, 200)) 9 MenuHelp = wx.Menu()10 aboutMenu = MenuHelp.Append(-1, u"对于(&A)")11 menuBar = wx.MenuBar()12 menuBar.Append(MenuHelp, u"帮忙(&H)")13 self.Bind(wx.EVT_TOOL, self.ShowAboutDlg, aboutMenu)14 self.SetMenuBar(menuBar)1516 def ShowAboutDlg(self, event):17 pos = self.GetPosition()18 dialog = MyDialog(self, -1, u"对于")19 dialog.SetPosition((pos[0] + 100, pos[1] + 60))2021class MyDialog(wx.Dialog):22 def __init__(self, parent, id, title):23 wx.Dialog.__init__(self, parent, id, title, size=(100, 100))24 self.panel = wx.Panel(self)25 self.OkBtn = wx.Button(self, 10, u"确定", pos=(8, 20), size=(80, 30))26 self.Bind(wx.EVT_BUTTON, self.CloseDlg, self.OkBtn)27 self.Show()28 # self.ShowModal()2930 def CloseDlg(self, event):31 self.Close()3233if __name__ == '__main__':34 app = wx.PySimpleApp()35 frame = MyFrame()36 frame.Show()37 app.MainLoop()成果：
提醒对话框

非凡对话框
包含文件关上对话框、字体对话框、色彩抉择对话框等\

wxPython库中的高级性能
剪贴板的操作
剪贴板是在各个利用之间替换数据的一种形式，一个应用程序能够将数据保留在剪贴板上，另外一个应用程序能够从剪贴板中获取数据。保留在剪贴板的数据能够是文本、图像或者是其余的文件对象等。

装置后进入 wxPython3.0 Docs and Demos\demo 所在目录，能够看到很多官网写的demo
运行形式：python run.py CheckBox.py
运行阐明：python 命令运行 run.py 脚本，而run.py脚本带有参数，该参数指向一个脚本文件，应用run.py脚本运行另外一个脚本。
