wxPython - 显示隐藏的单选按钮

在本文中，我们将学习如何显示隐藏的单选按钮。为了取消隐藏/显示单选按钮，我们可以使用 Show()函数。 Show()函数可用于显示和隐藏单选按钮。 Show()函数采用 show 布尔参数，如果为 True，则显示窗口。否则，隐藏它。

Syntax: wx.RadioButton.Show(self, show=True)

Parameters:

Parameter	Input Type	Description
show	bool	If True displays the window. Otherwise, hides it.

Return Type: bool

Returns: True if the window has been shown or hidden or False if nothing was done because it already was in the requested state.

代码示例：

import wx
  
APP_EXIT = 1
  
  
class Example(wx.Frame):
  
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
  
        self.InitUI()
    def InitUI(self):
        self.pnl = wx.Panel(self)
          
        # create radio button at position (30, 10)
        self.rb1 = wx.RadioButton(self.pnl, label ='Btn1', pos =(30, 10), size =(100, 20))
          
        # create button
        self.btn = wx.Button(self.pnl, label ='Btn1', 
                           pos =(30, 50), size =(100, 20))
  
        # hide radio button
        self.rb1.Hide()
  
        # bind event function
        self.btn.Bind(wx.EVT_BUTTON, self.Onclick)
      
    def Onclick(self, e):
            # show hidden radio button
            self.rb1.Show()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
