Re: [racket-users] Re: Executable file size and raco demod

Yes I’m scrolling in DrRacket. Somehow the scrolling behaviour is different between using the scroll bar, and the mouse wheel or touchpad. I think it’s using a different behaviour on these input devices. I could not find anything in the Windows event defs however. Dex _

Re: [racket-users] Re: Executable file size and raco demod

By default it’s set to ‘one. When set to ‘one, it’s having trouble detecting direction switch (up/down), especially when using touchpad or track point. The mouse wheel also feels sluggish. Once set to ‘integer, direction switches correctly and accurately, but scrolling is very slow on all inpu

Re: [racket-users] Re: Executable file size and raco demod

Are you scrolling in DrRacket's editor or in some other application? I'm surprised that change to the initial value of `wheel-steps-mode` has an effect, but maybe my confusion is that I'm thinking of DrRacket. An editor canvas calls `set-wheel-steps-mode` in its constructor to set the mode to 'int

[racket-users] Strange problem with racket/gui

Re: [racket-users] Re: Executable file size and raco demod

So in conclusion, only two changes required: In const.rkt: (define WHEEL_DELTA 120) to (define WHEEL_DELTA 30) In Window.rkt: (define wheel-steps-mode 'one) to (define wheel-steps-mode 'integer) The change to const.rkt may affect a lot more code, I'll

Re: [racket-users] Re: Executable file size and raco demod

One precision: this work for Racket 8.0 BC release. There might have been changes made to current. DrRacket feels as smooth as Sublime Text with this change, a completely different experience. I'd like to make a proper commit if somebody held my hand to do so. Dex On Saturday, April 10, 2021

Re: [racket-users] How to recover whitespace from syntax->string

I had to build something for this in my Resyntax project. My takeaways were: - There's no substitute for just reading the file. If you have a `syntax-original?` subform, you can use the srcloc information to read t

Re: [racket-users] Re: Executable file size and raco demod

Hi again, After playing around with the gen-wheels procedure and comparing its code with the WM_HSCROLL handling, I was able to get fast, accurate and smooth scrolling for both mouse and touchpad by switching the wheel-steps-mode to 'integer and reducing WHEEL_DELTA by a factor of 4. Here's t

Re: [racket-users] Re: Executable file size and raco demod

FYI I ended up going to 8.0 BC 32 bits to get the smallest executables for production, while still evaluating current. I partially fixed my scrolling problem by replacing (* wheel-scale amt) by (/ (* wheel-scale amt) 2) in share/pkgs/gui-lib/mred/private/wx/win32/window.rkt. There still is a
