初识python GUI(基于wxPyhton)

import wx
def load(event):
    file = open(r'd:\somefile.txt')
    contents.SetValue(file.read())
    file.close()


def save(event):
    file = open(r'd:\somefile.txt','w')
    file.write(contents.GetValue())
    file.close()


app = wx.App()
win = wx.Frame(None, title="simple editor", size=(410,335))
bkg = wx.Panel(win)


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(wx.HORIZONTAL)
hbox.Add(filename, proportion=1, flag=wx.EXPAND)
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()
