GooCanvasPolyline represents a polyline item, which is a series of one or more lines, with optional arrows at either end.
It is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".
It also implements the GooCanvasItem interface, so you can use the
GooCanvasItem functions such as goo_canvas_item_raise()
and
goo_canvas_item_rotate()
.
To create a GooCanvasPolyline use goo_canvas_polyline_new()
, or
goo_canvas_polyline_new_line()
for a simple line between two points.
To get or set the properties of an existing GooCanvasPolyline, use
g_object_get()
and g_object_set()
.
struct GooCanvasPolyline;
The GooCanvasPolyline struct contains private data only.
GooCanvasItem * goo_canvas_polyline_new (GooCanvasItem *parent
,gboolean close_path
,gint num_points
,...
);
Creates a new polyline item.
|
the parent item, or NULL . If a parent is specified, it will assume
ownership of the item, and the item will automatically be freed when it is
removed from the parent. Otherwise call g_object_unref() to free it. [skip]
|
|
if the last point should be connected to the first. |
|
the number of points in the polyline. |
|
the pairs of coordinates for each point in the line, followed by
optional pairs of property names and values, and a terminating NULL . |
Returns : |
a new polyline item. [transfer full] |
Here's an example showing how to create a filled triangle with vertices at (100,100), (300,100), and (200,300).
