Hi Stephen,

I offer the following piece to the puzzle:

(I tested it right now in DrRacket 7.3 and it still works)

Thank you @soegaard

[rfindler]

Is it possible to go from the result of get-handle to something that that screenshot code can use, @soegaard ?

@rfindler

Better late than never. I seem to have missed the message above.

Here is an updated version of the script that works with DrRacket 8.10. Note: Remember to allow "Screen recordings" for DrRacket in the system preferences.

It shows:

• how to capture an entire screen
• how to capture a single window
• how to recreate the widget gallery

The function (capture-window-with-name rx) takes a regular expression rx and captures the first window that has a name that matches.

Since the result of get-handle is a cairo_surface_t (which represents some drawing surface like bitmaps or canvases), I don't see how the screenshot functions can use a handle.
