Python provides wxpython package which allows us to create high functional graphical user interface. It is a cross-platform GUI toolkit for Python, Phoenix version Phoenix is the improved next-generation wxPython and it mainly focused on speed, maintainability and extensibility.
In this article, we are going to learn about SetValue() method associated with wx.RadioButton class of wxPython. SetValue() method sets the radio button to checked or unchecked status. This does not cause a wxEVT_RADIOBUTTON event to get emitted. If the radio button belongs to a radio group exactly one button in the group may be checked and so this method can be only called with value set to True. To uncheck a radio button in a group you must check another button in the same group.
Syntax: wx.RadioButton.SetValue(self, value)
Parameters:
Parameter | Input Type | Description |
---|---|---|
value | bool | True to check, False to uncheck. |
Example:
# 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 ):
# parent panel for radio buttons
self .pnl = wx.Panel( self )
# create radio buttons
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 ))
# set value for the second radio button as true(checked)
self .rb2.SetValue( True )
# main function def main():
# create an App object
app = wx.App()
# create an Example object
ex = Example( None )
ex.Show()
# running a app
app.MainLoop()
# Driver code if __name__ = = '__main__' :
# main function call
main()
