1. 按钮

按钮是GUI界面中必不可少的一环，在前面Tkinter中已经介绍过按钮，而且大家对按钮一定不陌生，那么我们直接进行语法的学习，wxPython中按钮的语法结构为：

1	`wx.Button(parent,` `id` `,label,pos,size,style,validator,name)`

它的相关参数与前面我们使用过的参数大致相同，下面我们使用Button按钮对上一节的登录界面进行修饰，代码如下：

1234567891011121314151617 import wx class Frame(wx.Frame): def __init__( self ): wx.Frame.__init__( self , None , wx.ID_ANY, "登陆" , size = ( 300 , 250 )) panel = wx.Panel( self , - 1 ) wx.StaticText(panel, wx.ID_ANY, "登录界面" , ( , 10 ),( 150 , - 1 ),wx.ALIGN_RIGHT) self .text = wx.StaticText(panel, wx.ID_ANY, "账户" , ( , 50 ),( 80 , - 1 ),wx.ALIGN_RIGHT) self .text = wx.StaticText(panel, wx.ID_ANY, "密码" , ( , 90 ),( 80 , - 1 ),wx.ALIGN_RIGHT) self .text = wx.TextCtrl(panel, wx.ID_ANY, "", ( 100 , 50 ),( 100 , 20 ),wx.ALIGN_LEFT) self .text = wx.TextCtrl(panel, wx.ID_ANY, "", ( 100 , 90 ), ( 100 , 20 ), wx.ALIGN_LEFT) self .button = wx.Button(panel, wx.ID_ANY, "登陆" , ( 70 , 120 ),( 50 , 20 ),wx.ALIGN_LEFT) self .button = wx.Button(panel, wx.ID_ANY, "注册" , ( 140 , 120 ), ( 50 , 20 ), wx.ALIGN_LEFT) if __name__ = = '__main__' : app = wx.App() frame = Frame() frame.Show( True ) app.MainLoop()

运行图如下：

2. 复选框和单选按钮

复选框对应前面我们学习过的Tkinter中的check控件，复选框提供多个按钮，可提供同时开关的功能，单选按钮对应Tkinter的radio控件，单选按钮提供多个按钮，但是只能选择其中一个按钮，在wxPython中我们使用wx.CheckBox和wx.RadioButton来创建复选框和单选按钮。

看下面的例子（复选框）：

12345678910111213 import wx class Frame(wx.Frame): def __init__( self ): wx.Frame.__init__( self , None , wx.ID_ANY, "复选框" , size = ( 300 , 250 )) panel = wx.Panel( self , - 1 ) self .box = wx.CheckBox(panel, - 1 , "Checkbox1" , pos = ( 50 , 50 ), size = ( 80 , 20 )) # 创建控件 self .box = wx.CheckBox(panel, - 1 , "Checkbox2" , pos = ( 50 , 70 ), size = ( 80 , 20 )) # 创建控件 self .box = wx.CheckBox(panel, - 1 , "Checkbox3" , pos = ( 50 , 90 ), size = ( 80 , 20 )) # 创建控件 if __name__ = = '__main__' : app = wx.App() frame = Frame() frame.Show( True ) app.MainLoop()

运行结果如图：

单选框代码如下：

1234567891011121314 import wx class MyFrame(wx.Frame): def __init__( self ): wx.Frame.__init__( self , None , - 1 , "选择一种喜欢的运动方式" , size = ( 300 , 100 )) panel = wx.Panel( self ) wx.StaticText(panel, wx.ID_ANY, "选择一种喜欢的运动方式" , ( , 10 ), ( 200 , - 1 ), wx.ALIGN_RIGHT) self .check1 = wx.RadioButton(panel, - 1 , "打篮球" , pos = ( 60 , 40 ), size = ( 50 , 20 ), style = wx.RB_GROUP) self .check2 = wx.RadioButton(panel, - 1 , "打乒乓球" , pos = ( 130 , 40 ), size = ( 50 , 20 )) self .check3 = wx.RadioButton(panel, - 1 , "跑步" , pos = ( 200 , 40 ), size = ( 50 , 20 )) if __name__ = = "__main__" : app = wx.App() frame = MyFrame() frame.Show() app.MainLoop()
