首先实现一个简单的记事本

import wx
    app = wx.App()
    win = wx.Frame(None, title = "Simple Editor", size = (410,335))
    bkg = wx.Panel(win) #背景组件
    
    loadButton = wx.Button(win, label = "Open", pos = (225,5), size = (80,25))
    saveButton = wx.Button(win, label = "Save", pos = (315,5), size = (80,25))
    filename = wx.TextCtrl(win, pos = (5,5), size = (210,25))
    contents = wx.TextCtrl(win, pos = (5,35), size = (390,260),
                           style = wx.TE_MULTILINE | wx.HSCROLL) #水平和垂直滚动条
    win.Show()
    app.MainLoop()

自动化智能布局的简单记事程序

import wx
    
    def load(event):
        file = open(filename.GetValue())
        contents.SetValue(file.read()) #读入到contents中
        file.close()
    
    def save(event):
        file = open(filename.GetValue(),'w')
        file.write(contents.GetValue())
        file.close()
    
    
    app = wx.App()
    win = wx.Frame(None, title = "Simple Editor", size = (410,335))
    bkg = wx.Panel(win) #背景组件
    
    loadButton = wx.Button(bkg, label = 'Open')
    loadButton.Bind(wx.EVT_BUTTON,load)
    
    saveButton = wx.Button(bkg, label = 'Save')
    saveButton.Bind(wx.EVT_BUTTON,save)
    
    filename = wx.TextCtrl(bkg)
    contents = wx.TextCtrl(bkg, style = wx.TE_MULTILINE | wx.HSCROLL)
    
    hbox = wx.BoxSizer()
    hbox.Add(filename, proportion = 1, flag = wx.EXPAND) #窗口变化时获取额外空间的比例
    hbox.Add(loadButton, proportion = 0, flag = wx.LEFT, border = 5)
    hbox.Add(saveButton, proportion = 0, flag = wx.LEFT, border = 5)
    
    vbox = wx.BoxSizer(wx.VERTICAL)
    vbox.Add(hbox, proportion = 0, flag = wx.EXPAND | wx.ALL,border = 5)
    vbox.Add(contents,proportion = 1,
             flag = wx.EXPAND | wx.LEFT | wx.BOTTOM | wx.RIGHT, border = 5)
    bkg.SetSizer(vbox)
    
    win.Show()
    app.MainLoop()
