wxWidgets UI笔记

（一）wx.Frame背景色修正

import wxclass MainFrame(wx.Frame):    def __init__(self):        wx.Frame.__init__(self, None, style=wx.DEFAULT_FRAME_STYLE)        self.SetBackgroundColour(wx.NullColour)        class App(wx.App):        def OnInit(self):        frame = MainFrame()        frame.Show()        return True    if __name__ == '__main__':    app = App()    app.MainLoop()

（二）常用界面布局

wxt.py

#!/usr/bin/env pythonimport datetimeimport wxdef ToPyDateTime(wxdate):    return datetime(wxdate.GetYear(), wxdate.GetMonth()+1, wxdate.GetDay())def StaticBoxSizer(orient, parent, label=''):    box = wx.StaticBox(parent, label=label)    sizer = wx.StaticBoxSizer(box, orient)    return sizerdef StaticTextSizer(orient, parent, label='', widget = None):    box = wx.BoxSizer(orient)    if orient == wx.HORIZONTAL:        box.Add(wx.StaticText(parent, -1, label), 0, wx.ALIGN_CENTER|wx.ALL, 5)        box.Add(widget, 1, wx.ALIGN_CENTER|wx.ALL, 5)    elif orient == wx.VERTICAL:        box.Add(wx.StaticText(parent, -1, label), 0, wx.TOP|wx.RIGHT|wx.LEFT, 5)        box.Add(widget, 0, wx.EXPAND|wx.RIGHT|wx.LEFT|wx.BOTTOM, 5)    return box
