cairo_create
Description:
[ Version ( deprecated = true , deprecated_since = "3.22" , since = "2.8" ) ]
public Context cairo_create (Window window)
Warning: cairo_create is deprecated since 3.22.
Creates a Cairo context for drawing to window.
Use begin_draw_frame and get_cairo_context instead
Note that calling reset_clip on the resulting Context will produce undefined results, so avoid it at all costs.
Typically, this function is used to draw on a Window out of the paint cycle of the toolkit; this should be avoided, as it breaks various assumptions and optimizations.
If you are drawing on a native Window in response to a gdk_expose event you should use begin_draw_frame and get_cairo_context instead. GTK will automatically do this for you when drawing a widget.
Parameters:
| window |
