The line item supports the following options, via the create_line method, and the itemconfig and itemcget configuration methods.
Table 16-1. Canvas Line Options
Option | Type | Description |
|---|---|---|
width | distance | The width of the line. Default is 1 pixel. |
fill | color | The color to use for the line. Default is "black". |

arrow | constant | If set to a value other than NONE, the line is drawn as an arrow. The option value defines where to draw the arrow head: FIRST, LAST, or BOTH. Default is NONE. The FIRST and LAST constants are not defined in Python 1.5.2 and earlier. For compatibility, use the strings "first" and "last" instead. |

capstyle | constant | For wide lines, this option controls how to draw the line ends. Use one of BUTT, PROJECTING, ROUND. Default is BUTT. These constants are not defined in Python 1.5.2 and earlier. For compatibility, use the strings "butt", "projecting", and "round" instead. |
joinstyle | const | For wide lines, this option controls how to draw the joins between edges. Use one of BEVEL, MITER, or ROUND. Default is ROUND. These constants are not defined in Python 1.5.2 and earlier. For compatibility, use the strings "bevel", "miter", and "round" instead. |
smooth | flag | If non-zero, the given coordinates are interpreted as b-spline vertices. |
splinesteps | int | The number of steps to use when smoothing this line. Default is 12. |
tags | tags | One or more tags to associate with this item. If only a single tag is to be used, you can use a single string instead of a tuple of strings. |
