how to create virtual keyboard using python, tkinter and pyautogui - part - 2

hello readers,

This Is Our Second part Of Virtual keyboard using python tutorial series. or you can say how to create virtual keyboard using python, tkinter and pyautogui module

and this is our second part.

if you are new visitor. then, first check our first part .

or

directly check our index.

but first, let me clear. what we have learnt in 1 part.

In 1st part,

we worked on GUI (Graphic User Interface).

as screenshot given below.

And In 2nd Part, (Current part)

We will Work on virtual keyboard events.

and for this i am using pyautogui python module.

so, first you need to install pyautogui.

Mac OS X

To Install this module on Mac OS X, you need the PyObjC module installed.

For Python 3, run:

sudo pip3 install pyobjc-core

sudo pip3 install pyobjc

sudo pip3 install pyautogui

For Python 2, run:

sudo pip install pyobjc-core

sudo pip install pyobjc

sudo pip install pyautogui

(There's some bug with their installer, so install pyobjc-core first or else

the install takes forever.)

Linux

To install this module on Linux, you need Xlib module installed.

For Python 3, run:

sudo apt-get install Xlib

sudo pip3 install python3-Xlib

sudo pip3 install pyautogui

For Python 2, run:

sudo apt-get install Xlib

sudo pip install Xlib

sudo pip3 install pyautogui

Windows.

To install this module on Windows, you do not need anything else.

sudo pip3 install pyautogui

So, let's move to script codes.

here basically,

i am adding some codes and features on virtual keyboard example.

if you want to see previous example then check our first part .

let me explain you what features i have added in current codes.

1. transparency

2. focus

3. key button working (using pyautogui python module.)

4. looks

here, i am sharing my Screen Shot.

and

here its my

Code 1.

after executing this codes.

you will got a well looking and a well working virtual codes.

as i already shared my screenshot.

if anyone from you want this updated example or want to contribute.

then, check here my repository. click here

so readers, i think this is enough for today.

In my next tutorial, i will show you more staff written in python language.

so, stay tuned with us.
