Hi!
When I create a 3D plot in DrRacket, I can rotate the plot by clicking on it
and dragging the mouse. Now I would like to embed the same plot with the same
ability in my GUI. Is there an easy way to do that?
Great idea!
Unfortunately, I didn't think of making an easy way to do it.
Fortunately, `plot' already does something similar: if you set
(plot-new-window? #t), plots appear on a canvas in a new frame. You just
need to do that without the frame.
The relevant code is in "<racket-dir>/collects/plot/common/gui.rkt",
specifically the `make-snip-frame' function.
The basic idea is to make a canvas containing a single read-only-text%
that is initially writable, insert the snip (which you get from
`plot-snip' or `plot3d-snip'), and then set the text to read-only. If
you want to change the plot, set the text writable, delete the snip,
insert the new one, and set it read-only again.
If you don't mind my asking, what are you plotting in your gui?
