[racket-users] Re: Creating movable Fonts on a Canvas

Have a look at the `snip%` and `pasteboard%` classes: you can represent each glyph using a `snip%` and the pasteboard will handle the moving it with the mouse. You can derive the `snip%` and `pasteboard%` objects to add new functionality -- this is easier than implementing a mouse move operati

[racket-users] Creating movable Fonts on a Canvas

If i want to use fonts on a canvas in a way that each single Glyph/Font is movable around the canvas by mouse, is it a good idea to have a class drivative of canvas% for each new font and then override the on-event method of them to update its coordinates on the main canvas? Or is there a bette

Re: [racket-users] Relative Pathname problem

Re: [racket-users] Jupyter Racket Kernel - iracket

Hi, I am trying to install racket for jupyter on a mac, and from the github it is not clear for me how to do it. I use Dr Racket, still running "raco pkg install iracket" is not recognized in the mac shell. Thanks, Ari On Friday, May 4, 2018 at 9:57:42 AM UTC+3, Graham Dean wrote: > > Pleasu
