Attributes

renderer : `RendererBase`

The renderer for the draw event.

In most backends, callbacks subscribed to this event will be fired after the rendering is complete but before the screen is updated. Any extra artists drawn to the canvas's renderer will be reflected without an explicit call to blit .

warning

Calling canvas.draw and canvas.blit in these callbacks may not be safe with all backends and may cause infinite recursion.

A DrawEvent has a number of special attributes in addition to those defined by the parent Event class.

An event triggered by a draw operation on the canvas.

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
