Tkinter Tutorial Canvas Chapter (1)

''''Tkinter Tutorial Canvas Chapter (1)'''


# Provides a Container that can be used for drawing and supports basic geometric elements. When using Canvas for drawing, all Operations are all done through Canvas, not through its elements


# Elements can be represented using handle or tag.


'''1. The first Canvas program'''


# -*- coding: cp936 -*-


# Specify the color of the canvas as white

from Tkinter import *
root = Tk()

# Create a Canvas and set its background color to white

cv = Canvas(root,bg = 'white')
cv.pack()
root.mainloop()

# For the sake of clarity, set the background color to white to distinguish the root



##'''2. Create an item'''


# -*- coding: cp936 -*-


# Create a rectangle and specify the canvas color as white


from Tkinter import *


root = Tk()


# Create a Canvas and set its background color to white


cv = Canvas(root,bg = 'white ')


# Create a rectangle with coordinates (10,10,110,110)

cv.create_rectangle(10,10,110,110)
cv.pack()
root.mainloop()

# For obviousness, set the background color to white , to distinguish the root


'''3. Specify the fill color of the item'''


# -*- coding: cp936 -*-


# Create a rectangle and specify the background color of the canvas to be white


# Use the attribute fill to set its fill color


from Tkinter import *


root = Tk()


# Create a Canvas and set its background color to white

cv = Canvas(root,bg = 'white')
cv.create_rectangle(10,10,110,110,fill = 'red')
cv.pack()
root.mainloop()

# Specify the filling of the rectangle The color is red

'''4. Specify the border color of the item'''


# -*- coding: cp936 -*-


# Create a rectangle and specify the background color of the canvas to be white


# Use the attribute outline to set its border color


from Tkinter import *


root = Tk()


# Create a Canvas and set its background color to white

cv = Canvas(root,bg = 'white')
cv.create_rectangle(10,10,110,110,outline = 'red')
cv.pack()
root.mainloop()

# Specify the border color of the rectangle as red


'''5. Specify the width of the border'''


# -*- coding: cp936 -*-


# Specify the background color of the canvas to be white


# Use the attribute width to specify the width of the line


from Tkinter import *


root = Tk()


# Create a Canvas and set its background color to white

cv = Canvas(root,bg = 'white')
cv.create_rectangle(10,10,110,110,outline = 'red',width = 5)
cv.pack()
root.mainloop()

# Specify the border color of the rectangle is red, set the line width to 5, note that it is different from the width of Canvas.


'''6. Draw a dotted line'''


# -*- coding: cp936 -*-


# Specify canvas The background color is white


# Use attribute dash, this value can only be odd


from Tkinter import *


root = Tk ()


# Create a Canvas and set its background color to white

cv = Canvas(root,bg = 'white')
cv.create_rectangle(10,10,110,110,
outline = 'red',
dash = 10,
fill = 'green')
cv.pack()
root.mainloop()

# Specify the border color of the rectangle to be red, Draw a dotted line


'''7. Use the brush to fill'''


# -*- coding: cp936 -*-


# Specify the background color of the canvas to be white


# Use the attribute stipple

from Tkinter import *
root = Tk()

# to create a Canvas and set its background color Is white

cv = Canvas(root,bg = 'white')
cv.create_rectangle(10,10,110,110,
outline = 'red',
stipple = 'gray12',
fill = 'green')
cv.pack()
root.mainloop()

# Specify the border color of the rectangle as red, customize the brush

'''8. Modify the coordinates of the item' ''


# -*- coding: cp936 -*-


# Specify the background color of the canvas as white


# Use Canvas Method to reset the coordinates of the item

from Tkinter import *
root = Tk()

# Create a Canvas and set its background color to white

cv = Canvas(root,bg = 'white')
rt = cv.create_rectangle(10,10,110,110,
outline = 'red',
stipple = 'gray12',
fill = 'green')
cv.pack()

# Reset the coordinates of rt (equivalent to moving an item)

cv.coords(rt,(40,40,80,80))
root.mainloop()

# Dynamically modify the coordinates of the item
