Tkinter 8.5 reference: a GUI for Python |  |
For pleasant and effective rendering of diagrams, sometimes it is a good idea to pay attention to cap and join styles.
The cap style of a line is the shape of the end of the line. Styles are:
tk.BUTT: The end of the line is cut off square at a line that passes through the endpoint.tk.PROJECTING: The end of the line is cut off square, but the cut line projects past the endpoint a distance equal to half the line's width.tk.ROUND: The end describes a semicircle centered on the endpoint.
The join style describes the shape where two line segments meet at an angle.
tk.ROUND: The join is a circle centered on the point where the adjacent line segments meet.tk.BEVEL: A flat facet is drawn at an angle intermediate between the angles of the adjacent lines.tk.MITER: The edges of the adjacent line segments are continued to meet at a sharp point.
This illustration shows how Tkinter's cap and join options work with a line made of two connected line segments. Small red circles show the location of the points that define this line.
