wxPython 显示隐藏的单选框

在这篇文章中，我们将学习如何显示隐藏在框架中的无线电盒。为了达到这个目的，我们将使用Show()方法。Show()方法既可用于隐藏，也可用于显示一个部件。

Show需要一个布尔参数show，如果为真，则显示该部件，否则隐藏该部件。

语法：wx.RadioBox.Show(self, show=True)

参数

返回类型: bool

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 box containing above list
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                                majorDimension = 1, style = wx.RA_SPECIFY_ROWS)
  
        # create a button in the frame
        self.btn = wx.Button(pnl, 1, "Hide RadioBox", pos =(125, 100));
        # create a button in the frame
        self.btn1 = wx.Button(pnl, 2, "Show RadioBox", pos =(125, 150));
  
        # bind a function with button btn
        self.btn.Bind(wx.EVT_BUTTON, self.onclick)
        # bind a function with button btn1
        self.btn1.Bind(wx.EVT_BUTTON, self.onclick1)
  
        # set frame in centre
        self.Centre()
  
        # set size of frame
        self.SetSize((400, 250))
  
        # show output frame
        self.Show(True)
  
    def onclick(self, e):
        # hide radio box from the frame
        self.rbox.Show(False)
  
    def onclick1(self, e):
        # shows radio box
        self.rbox.Show()
  
  
# wx App instance
ex = wx.App()
# Example instance
FrameUI(None, 'RadioButton and RadioBox')
ex.MainLoop()
