wxPython – wx.RadioButton 中的 GetValue() 方法

Python提供wxpython 包允许我们创建功能强大的图形用户界面。它是Python的跨平台GUI工具包，Phoenix版Phoenix是改进的下一代wxPython，主要关注速度、可维护性和可扩展性。

在本文中，我们将学习与 wxPython 的wx.RadioButton类关联的GetValue() 方法。 GetValue()函数用于在选中单选按钮时返回 True，否则返回 False。
GetValue()函数不需要参数。

Syntax:  wx.RadioButton.GetValue(self)

Parameters:  GetValue() function needs no arguments.

Return : return True if the radio button is checked, False otherwise
 

例子：

Python3

# importing wx library
import wx
 
APP_EXIT = 1
 
# create a Example class
class Example(wx.Frame):
   
    # constructor
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
         
        # method calling
        self.InitUI()
 
    # method for user interface creation
    def InitUI(self):
 
        # create a parent panel for radio buttons
        self.pnl = wx.Panel(self)
 
        # create a radio buttons in frame
        self.rb1 = wx.RadioButton(self.pnl,
                                  label = 'Button 1',
                                  pos = (30, 10))
        self.rb2 = wx.RadioButton(self.pnl,
                                  label = 'Button 2',
                                  pos = (30, 30))
        self.rb3 = wx.RadioButton(self.pnl,
                                  label = 'Button 3',
                                  pos = (30, 50))
 
        # change value of second button to True
        self.rb2.SetValue(True)
         
        # print values of radio buttons True
        # if checked, False otherwise
        print(self.rb1.GetValue())
        print(self.rb2.GetValue())
        print(self.rb3.GetValue())
 
# main function
def main():
   
      # create a App object
    app = wx.App()
    # create a Example object
    ex = Example(None)
     
    ex.Show()
     
    # running a app
    app.MainLoop()
 
# Driver code
if __name__ == '__main__':
   
  # main function call
  main()

输出：

False
True
False
