wxPython – Create Radio Box with two step creation
  • Last Updated : 29 Jun, 2020

In this article we are going to learn to create a radio box in a frame. A radio box item is used to select one of number of mutually exclusive choices. It is displayed as a vertical column or horizontal row of labelled buttons.

In order to create radio box we will use Create() function in wx.RadioBox class of wxPython. Create() function takes different attributes of radio box as parameter.

Syntax:
wx.RadioBox.Create( parent, id=ID_ANY, label=””, pos=DefaultPosition,
size=DefaultSize, choices=[], majorDimension=0, style=RA_SPECIFY_COLS,
validator=DefaultValidator, name=RadioBoxNameStr )

Parameters:

ParameterInput TypeDescription
parentwx.WindowParent window. Should not be None.
idwx.WindowIDControl identifier. A value of -1 denotes a default value.
labelstringText Label.
poswx.PointWindow position.
sizewx.WindowWindow size.
choiceslist of stringsWindow style.
majorDimensionintSpecifies the maximum number of rows (if style contains RA_SPECIFY_ROWS ) or columns (if style contains RA_SPECIFY_COLS ) for a two-dimensional radiobox. The default value of 0 means to use the number of items, i.e. number of elements in choices.
stylelongAn array of choices with which to initialize the radiobox.
validatorwx.ValidatorWindow validator.
namestringWindow name.

Code Example:






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 = ['Value X', 'Value Y', 'Value Z']
  
        # create radio box
        self.rbox = wx.RadioBox()
  
        # create with two step creation using Create() function
        self.rbox.Create(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                              majorDimension = 1, style = wx.RA_SPECIFY_ROWS)
        # 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()
