wxPython – Create Radio Box with two step creation

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:

Parameter	Input Type	Description
parent	wx.Window	Parent window. Should not be None.
id	wx.WindowID	Control identifier. A value of -1 denotes a default value.
label	string	Text Label.
pos	wx.Point	Window position.
size	wx.Window	Window size.
choices	list of strings	Window style.
majorDimension	int	Specifies 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.
style	long	An array of choices with which to initialize the radiobox.
validator	wx.Validator	Window validator.
name	string	Window 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()
