FUN WITH CODING
TKINTER - STYLING OBJECTS

WHAT IS IN THIS SECTION

---

This section cover some styling elements when using Tkinter such as text, colour, buttons, images, banners and the use of frames and canvas to allow slick change of screens.

CHANGE TEXT FONT AND SIZE

---

You can change the font and size of the text you use without any additional library imports by using the method in the example below:
myText.config(font=("Courier", 44))
See an example used in the code below and feel free to copy and try it out.

from tkinter import *

screen = Tk()
screen.minsize(400,400)# H / V
screen.title("Changing the Font")
screen.configure(background="#71d0c8")

pageTitle = Label(screen, text = "This is my font")
pageTitle.config(font=("Courier", 35))
pageTitle.place(x = 20, y = 20)

pageTitle = Label(screen, text = "This is my font")
pageTitle.config(font=("Georgia", 30))
pageTitle.place(x = 20, y = 80)

pageTitle = Label(screen, text = "This is my font", bg = "#71d0c8")
pageTitle.config(font=("Comic Sans MS", 25))
pageTitle.place(x = 20, y = 140)

BUTTON STYLES AND SIZE

---

Button text align: anchor = N (also use S,W,E)

...

TIME DELAY A POP-UP MESAGE

---

This shows how using the .after method you can set a delay on an action. In this example the 'Welcome' message shows for 2 seconds then disappears.

from tkinter import *

screen = Tk()
screen.minsize(305,475)# H / V
screen.title("Using time delay")
screen.configure(background="#71d0c8")

userName = ("Bob")

def homeScreen(userName):
   welcome = Label(screen, text = "Welcome " + userName)
   welcome.place(x = 100, y = 40)
   welcome.after(2500, removeEntry)#Delays for 2500 the runs the function removeEntry

def removeEntry():
   for i in screen.winfo_children():
      i.destroy()

homeScreen(userName)

screen.mainloop()

PLACING A MATPLOTLIB GRAPH IN A TKINTER WINDOW

---

from tkinter import *
from pandas import DataFrame
import matplotlib.pyplot as plt
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

#Creates the library to hold the data
data = {'Technology': ["Mac","PC","Google Home","Playstation","C64","GoPro","Samsung","iphone","Huawei","X-Box"],
         'User_Rating': [21,45,35,76,34,87,34,5,60,50]}
#Select the variable data for the data to use and then make the
#column equal the technology library index and user rating index
df1 = DataFrame(data,columns=['Technology','User_Rating'])

screen = Tk()
screen.minsize(600,600)
screen.title ("Matplotlib with Tkinter")

myChart = plt.Figure(figsize=(8,5), dpi=100)#Chart size parameters
ax1 = myChart.add_subplot(111)#Grid parameters of the chart
bar1 = FigureCanvasTkAgg(myChart, screen)
bar1.get_tk_widget().pack()
df1 = df1[['Technology','User_Rating']].groupby('Technology').sum()
df1.plot(kind='bar', legend=True, ax=ax1)
ax1.set_title('Technology and Consumer Rating')

screen.mainloop()
