wxPython – Change background colour of RadioBox

In this article we are going to learn how can we change the background colour of Radio Box present in the frame. In order to do that we are going to use SetBackgroundColour() method. SetBackgroundColour() function takes wx.Colour argument which will be used as background colour for Radio Box.

Syntax: wx.RadioBox.SetBackgroundColour(self, colour)
Parameters

Parameter	Input Type	Description
colour	wx.Colour	Colour to be used for background.

Code Example:

Python3

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 = ['Radio One', 'Radio Two']

        # create radio box containing above list
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                                         majorDimension = 1, style = wx.RA_SPECIFY_ROWS)

        # change background colour for radio box
        self.rbox.SetBackgroundColour((150, 150, 200, 255))

        # 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()
