wxPython - 通过两步创建创建单选框

在本文中，我们将学习在框架中创建一个单选框。单选框项目用于选择多个互斥选项之一。它显示为带有标签的按钮的垂直列或水平行。

为了创建单选框，我们将使用 wxPython 的 wx.RadioBox 类中的 Create()函数。 Create()函数将单选框的不同属性作为参数。

Syntax:
wx.RadioBox.Create( parent, id=ID_ANY, label=””, pos=DefaultPosition,
size=DefaultSize, choices=[], majorDimension=0, style=RA_SPECIFY_COLS,
validator=DefaultValidator, name=RadioBoxNameStr )

Parameters:

Parameter	Input Type	Description
parent	wx.Window	Parent window. Should not be None.
id	wx.WindowID	Control identifier. A value of -1 denotes a default value.
label	string	Text Label.
pos	wx.Point	Window position.
size	wx.Window	Window size.
choices	list of strings	Window style.
majorDimension	int	Specifies the maximum number of rows (if style contains RA_SPECIFY_ROWS ) or columns (if style contains RA_SPECIFY_COLS ) for a two-dimensional radiobox. The default value of 0 means to use the number of items, i.e. number of elements in choices.
style	long	An array of choices with which to initialize the radiobox.
validator	wx.Validator	Window validator.
name	string	Window name.

代码示例：

import wx
  
  
class FrameUI(wx.Frame):
  
    def __init__(self, parent, title):
        super(FrameUI, self).__init__(parent, title = title, size =(300, 200))
  
        # function for in-frame components
        self.InitUI()
  
    def InitUI(self):
        # parent panel for radio box
        pnl = wx.Panel(self)
  
        # list of choices
        lblList = ['Value X', 'Value Y', 'Value Z']
  
        # create radio box
        self.rbox = wx.RadioBox()
  
        # create with two step creation using Create() function
        self.rbox.Create(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                              majorDimension = 1, style = wx.RA_SPECIFY_ROWS)
        # set frame in centre
        self.Centre()
        # set size of frame
        self.SetSize((400, 250))
        # show output frame
        self.Show(True)
  
  
# wx App instance
ex = wx.App()
# Example instance
FrameUI(None, 'RadioButton and RadioBox')
ex.MainLoop()
