python的GUI的运用（wxpython）

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()
