pub struct DrawContext { /* private fields */ }
Expand description
Base class for objects implementing different rendering methods.
DrawContext
is the base object used by contexts implementing different
rendering methods, such as CairoContext
or GLContext
.
It provides shared functionality between those contexts.
You will always interact with one of those subclasses.
A DrawContext
is always associated with a single toplevel surface.
This is an Abstract Base Class, you cannot instantiate it.
§Properties
§display
