wxPython - 创建具有不同方向的项目的单选框

在本文中，我们将学习如何创建一个单选框，其中包含水平和垂直方向的项目。为此，我们将在创建单选框时使用样式参数。

Radio Box中有两种样式。

wx.RA_SPECIFY_ROWS：主要维度参数是指最大行数。
wx.RA_SPECIFY_COLS：主要维度参数是指最大列数。

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

To set direction vertical we will use wx.RA_SPECIFY_ROWS
To set number of items per row we will use majorDimension parameter.
To set direction horizontal we will use wx.RA_SPECIFY_COLS
To set number of items per columns we will use majorDimension parameter.

编程需要懂一点英语

代码示例：

Python3

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
        hlist = ['Item One', 'Item Two']
        vlist =['Item One', 'Item Two']
 
        # create radio box with items in horizontal orientation
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(10, 10), choices = hlist,
                                majorDimension = 0, style = wx.RA_SPECIFY_ROWS)
 
        # create radio box with items in vertical orientation
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(240, 10), choices = vlist,
                                majorDimension = 0, style = wx.RA_SPECIFY_COLS)
        # 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()
