plopp.widgets.drawing.DrawingTool#

class plopp.widgets.drawing.DrawingTool(figure, input_node, tool, func, destination, get_artist_info, value=False, **kwargs)[source]#

Interface between Plopp and Mpltoolbox.

Parameters:

figure (FigureLike) – The figure where the tool will draw things (points, lines, shapes…).
input_node (Node) – The node that provides the raw data which is shown in figure.
tool (Any) – The Mpltoolbox tool to use (Points, Lines, Rectangles, Ellipses…).
func (Callable) – The function to be used to make a node whose parents will be the input_node and a node yielding the current state of the tool (current position, size).
destination (Union[FigureLike, Node]) – Where the output from the func node will be then sent on. This can either be a figure, or another graph node.
get_artist_info (Callable) – A function that returns another function which will convert the properties of the artist that produced the event to something (usually a dict) that is usable by the destination.
value (bool, default: False) – Activate the tool upon creation if True.
**kwargs – Additional arguments are forwarded to the ToggleTool constructor.
