wxPython – wx.RadioBox 中的 GetString() 方法

在本文中，我们将学习与 wxPython 的 wx.RadioBox 类关联的 GetString() 方法。 GetString() 方法仅用于返回具有给定索引的项目的标签。

它将对应项的索引作为参数。

Syntax: wx.RadioBOx.GetString(self, n)

Parameters

Parameter	Input Type	Description
n	int	The zero-based index.

Returns: The label of the item or an empty string if the position was invalid.

Return Type: string

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 = ['Radio One', 'Radio Two']
  
        # create radio boc containing above list
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                                          majorDimension = 1, style = wx.RA_SPECIFY_ROWS)
  
        # set tooltip for first tool
        self.rbox.SetItemToolTip(0, "Item One")
  
        # print the label string of item at index 0
        print (self.rbox.GetString(0))
  
  
        # 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()

控制台输出：
