goocanvas.PolylineModel Properties

"arrow-length" Read/Write The length of the arrows, as a multiple of the line width. Allowed values: >= 0. Default value: 5.
"arrow-tip-length" Read/Write The length of the arrow tip, as a multiple of the line width. Allowed values: >= 0. Default value: 4.
"arrow-width" Read/Write The width of the arrows, as a multiple of the line width. Allowed values: >= 0. Default value: 4.
"close-path" Read/Write If the last point should be connected to the first. Default value: False.
"end-arrow" Read/Write If an arrow should be displayed at the end of the polyline. Default value: False.

Implemented Interfaces

goocanvas.PolylineModel implements goocanvas.ItemModel

Description

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

Constructor

goocanvas.PolylineModel(properties= None);

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

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.PolylineModel(parent = root,
                                       points=p_points,
                                       close_path=True,
                                       stroke_color="red",
                                       fill_color="blue")

Functions

goocanvas.polyline_model_new_line

goocanvas.polyline_model_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 model item with a single line.
