How to Create Custom widgets with wxPython

In this wxPython article we want to learn about How to Create Custom widgets with wxPython, wxPython is powerful library for creating desktop applications using Python programming language. on of the best thing about wxPython is creating custom widgets. custom widgets can be used to enhance the functionality of an application, it allows developers to create unique user interfaces that stand out from the rest.

How to Create Custom widgets with wxPython

First of all we need to install wxPython

pip install wxPython

1	pip install wxPython

First step in creating a custom widget is to subclass an existing wxPython widget. this allows you to take advantage of the functionality that is already built into the base widget, and also adding your own custom behavior.

For example, let’s say that we want to create custom button widget that displays a message when it is clicked. we can start by subclassing wx.Button widget:

import wx

class CustomButton(wx.Button):
    def __init__(self, parent, label):
        super().__init__(parent, label=label)
        self.Bind(wx.EVT_BUTTON, self.on_button_click)

    def on_button_click(self, event):
        wx.MessageBox("Welcome to geekscoders.com")

import wx

class CustomButton(wx.Button):

def __init__(self, parent, label):

super().__init__(parent, label=label)

self.Bind(wx.EVT_BUTTON, self.on_button_click)

def on_button_click(self, event):

wx.MessageBox("Welcome to geekscoders.com")

After that you have created your custom widget, you can use it just like any other wxPython widget. for example if we want to use our custom button in wxPython application, we can create an instance of the CustomButton class and add it to a sizer:

class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(None, title="Custom Widget Example")
        sizer = wx.BoxSizer(wx.VERTICAL)
        btn = CustomButton(self, label="Click me")
        sizer.Add(btn, 0, wx.ALL, 10)
        self.SetSizer(sizer)

class MyFrame(wx.Frame):

def __init__(self):

super().__init__(None, title="Custom Widget Example")

sizer = wx.BoxSizer(wx.VERTICAL)

btn = CustomButton(self, label="Click me")

sizer.Add(btn, 0, wx.ALL, 10)

self.SetSizer(sizer)

In this example we have created MyFrame class that subclasses wx.Frame widget. after that we creates an instance of the CustomButton class and add it to a sizer using Add method. and lastly we set the sizer for the frame using the SetSizer method.
