Implemented Interfaces

goocanvas.Polyline implements goocanvas.Item

Description

goocanvas.Polyline represents a polyline item, which is a series of one or more lines, with optional arrows at either end. It is a subclass of goocanvas.ItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width". It also implements the goocanvas.Item interface, so you can use the goocanvas.Item functions such as goocanvas.Item.raise_() and goocanvas.Item.rotate()

Constructor

    goocanvas.Polyline(properties=None)

`properties` :	A comma separated list of properties.
Returns :	A new `goocanvas.Polyline`

Creates a new canvas polyline item.

Here's an example showing how to create a filled triangle with vertices at (100,100), (300,100), and (200,300).

	p_points = goocanvas.Points([(100.0, 100.0), (300.0, 100.0), (200.0, 300.0)])
	polyline = goocanvas.Polyline(points=p_points, close_path=True, stroke_color="red", fill_color="blue")

Functions

goocanvas.polyline_new_line

    def goocanvas.polyline_new_line(parent, x1, y1, x2, y2, properties)

`parent` :	The parent item, or None.
`x1` :	The x coordinate of the start of the line.
`y1` :	The y coordinate of the start of the line.
`x2` :	The x coordinate of the end of the line.
`y2` :	The y coordinate of the end of the line.
`properties` :	A comma separated list of properties.

Creates a new polyline item with a single line.
