Re: [racket] Using GUI editor

A dc<%> object doesn't work like that. If you want to draw something into it, you have to set up a callback and draw during the dynamic extent of the callback. Also, if you do that, you probably want to use a canvas% object, not an editor-canvas%. The editor-canvas% objects already do a lot of work

Re: [racket] Best canonical package?

I feel this is hard to answer because there are still different tastes for what it best. I think the opengl package is pretty good, if relatively simple to the point where there's not much to do wrong. Jay On Fri, Sep 20, 2013 at 10:07 AM, Anthony Carrico wrote: > Is there a package that represe

Nice. Delegating something like 24/7/365 uptime to Amazon S3 is smart. (And good for dental hygiene :)). On Fri, Sep 20, 2013 at 4:53 PM, Jay McCarthy wrote: > The current plan for reliability is to switch the package catalog to > be served from a static S3 site that redirects dynamic work to th

The current plan for reliability is to switch the package catalog to be served from a static S3 site that redirects dynamic work to the current server. On Fri, Sep 20, 2013 at 2:19 PM, Greg Hendershott wrote: > I'm using Travis CI for some projects that need to `raco pkg install` > some required

Re: [racket] pkg.racket-lang.org down?

I'm using Travis CI for some projects that need to `raco pkg install` some required packages. On a few occasions I've had Travis CI mark something "build failed", and the reason was the package install failed (otherwise the build would have succeed). There are two links in the chain: The pkg.racke

You could use a large pen and just not draw the center part at all. Robby On Fri, Sep 20, 2013 at 12:51 PM, J. Ian Johnson wrote: > I'm trying to make some visuals for a slideshow presentation, and I want > to have a ring with borders (inner and outer ring borders) to draw over > another image

[racket] Best canonical package?

Is there a package that represents the current best practice for the new package system (naming, organizing, modules, submodules, files, docs, tests, READMEs, the works)? I know a lot of them were ported forward, and this area is evolving. A really decent example would be nice. -- Anthony Carrico

It looks like I've stumbled into another area where I'm lacking a basic understanding of what's going on. I'm trying to use the built-in editor in the gui package, but I need to put some initial content into the editor window. When I put the following in the editor pane and run it, I get the gui e

Re: [racket] Annulus with dc%?

Here is one way to draw an annulus on a 400x400 bitmap with center (200,200) and radii 100 and 200 respectively. #lang racket (require racket/draw) (define bm (make-object bitmap% 400 400)) (define dc (new bitmap-dc% [bitmap bm])) (define p (new dc-path%)) (send p move-to 300 200) (send p arc 10

[racket] Annulus with dc%?

I'm trying to make some visuals for a slideshow presentation, and I want to have a ring with borders (inner and outer ring borders) to draw over another image, thus a transparent center is necessary. I haven't been able to find a way to do this with the current API. Anyone have a suggestion (oth

Re: [racket] How to get a pict-box into a slideshow?

Something along those lines is what I had in mind, right. A pict box just produces a pict, not something that specially knows about subpicts (more than any other pict would). You can iterate over subpicts, I believe, but what you're doing is probably better than that. Robby On Fri, Sep 20, 2013
