The Canvas widget lets us display various graphics on the application. It can be used to draw simple shapes to complicated graphs. We can also display various kinds of custom widgets according to our needs.
C = Canvas(root, height, width, bd, bg, ..)
- root = root window.
- height = height of the canvas widget.
- width = width of the canvas widget.
- bg = background colour for canvas.
- bd = border of the canvas window.
- scrollregion (w, n, e, s)tuple defined as a region for scrolling left, top, bottom and right
- highlightcolor colour shown in the focus highlight.
- cursor It can defind as a cursor for the canvas which can be a circle, a do, an arrow etc.
- confine decides if canvas can be accessed outside the scroll region.
- relief type of the border which can be SUNKEN, RAISED, GROOVE and RIDGE.
Some common drawing methods
- Creating an Oval
oval = C.create_oval(x0, y0, x1, y1, options)
- Creating an arc
arc = C.create_arc(20, 50, 190, 240, start=0, extent=110, fill="red")
- Creating a Line
line = C.create_line(x0, y0, x1, y1, ..., xn, yn, options)
- Creating a polygon
oval = C.create_polygon(x0, y0, x1, y1, ...xn, yn, options)
