python使用wx绘界面，布局自已的toolbar，使控件右对齐

正确的右对齐方法：

panel = wx.Panel(self)button = wx.Button(panel, label = _(u'确定'), size = (60, 28))hbox = wx.BoxSizer(wx.HORIZONTAL)hbox.Add(button, 0, wx.ALL | wx.ALIGN_RIGHT, 10)panel.SetSizer(hbox)panel.SetAutoLayout(True)

wx中的Sizer的add讲解

Add(self,item,proportion=0,flag=0,border=0, userData=None)

item,与userData参数就不必讲解了，主要是proportion，flag，border三者的配合.

当flag有wx.EXPAND值时， proportion取0表示横向扩展，大于零表示同时横竖扩展，小于零应该只扩展竖方向。

当然flag中 存在wx.TOP，wx.BOTTOM，wx.LEFT，wx.RIGHT，wx.ALL中值时，表示与其它控件保持多少像素的距离，border参数指定

最后flag中的wx.ALIGN_* 开头的值就表示对齐方向，

例如如果想某控件一直右对齐，就在此控件左边放一个空sizer，如: box.Add((1,1), 0, wx.EXPAND,0 ), 其中必需有expand,第二个参数取0

下面是没找到官方正确布局的异端方法，大家学。

wx 布局真蛋痛，还是我没找到方法使控件右对齐. 最后只能自绘，绑定EVT_SZIE事件

wx要布局，一定要在panel上放控件，frame上最少要有一个panel
