SmoothDivScroll is wonderfull script! But does anyone know if the new beta version of SmoothDivScroll (version 1.2) is working in IE 6, 7 and 8? I saw in the google Group of Thomas Kahn that this questions was also raised. I'm trying to get it working but can't get some features working and I don't know if it is my mistake or not. I hope Thomas himself sees this post and will react on it. And if the conclusion is that it is not working on these versions of IE, I would like to know if Thomas will work to get it also on IE working or if he leaves it as it is now. Of course I hope this, because it is wonderful code!

Yes, SmoothDivScroll 1.2 should work OK in older versions of Internet Explorer. I don't have a computer that is old enough to have a "real" installation of IE6 but I do have a virtual machine running Windows XP SP3 and Internet Explorer 6 (which is basically the same thing as a real installation).
When I tested on this machine there was one issue that had to do with the height of the hotspots. For some reason the hotspots do not fill out the entire height of the scrollable area. Currently I have no fix and to be perfectly honest I don't think I will spend time looking for a solution since IE6 is a browser that is becoming more and more marginalized. If anyone has a solution - let me knoe! I haven't made up my mind about IE7 yet. But I do want it to work fine in IE8 and IE9 though since these two versions are alive and kicking.
Two follow up questions:
Which features are not working and in what versions of
Internet Explorer?
Do you have a demo somewhere that I can look at? Since
SmoothDivScroll is a plugin that depends heavily on the surrounding
code on the page, in many cases errors in the HTML and/or the CSS is
the source of the errors.
Then again - sometimes the bungling is on my part. It's been known to happen. :-)

I'm not really understanding why I'm seeing this error crypto.randomUUID is not a function when viewing said web app on iOS Simulator's Safari, when simulating any of the devices (iPad, iPhone, etc). I understand what the error means, I'm just surprised that randomUUID is not supported. It works on any other desktop browser, including physical iPad and iPhone devices. Is the simulator lacking something that I'm not understanding that needs configuration? I assume the simulator should be faithful to the actual hardware.
No one has answered this yet and you've probably solved this on your own already. Most of version 15 doesn't support crypto. IIRC versions 15.0 through 15.3 (maybe i think even to 5); Anything after that is fine. I say maybe because Apple doesn't state this anywhere as far as I'm aware. I've discovered this on my own through testing for work.
This hacky but you can get around this by adding a polyfill (I know it stings) I wouldn't expect Apple to remedy this any time soon because it feels like they gave up on Safari IMO.
I installed Racket 8.5 on my MacBook (MacOS Ventura Beta) and ran into a number of problems:
the application windows don't close on the cross, even the ones that are considered additional menus and shouldn't work that way anyway. Add video
In projects from my computer, the functions do not work correctly. And this error appears even if I move the author's code into my Racket in a clean project. For example, from a project downloaded from the Internet, where the author writes:
empty-scene 100 100 "blue"
In his project everything works fine, this function is in the Racket documentation.
If I write this function in my project, Racket gives me an error;
empty-scene: expects only 2 arguments, but found 3
I tried to find information about this on the Internet, I reinstalled Racket and downloaded different versions of the program, but the problem persists.
Has anyone encountered similar problems? Are there any tips on how to fix it?
I have no idea about the window thing: this doesn't happen on macOS 11 and I suspect is an artifact of running it on some beta version of macOS.
The arguments are because you're not in fact using 2htdp/image but htdp/image, which provides a different version of empty-scene. This is clear from looking at your video.
Also, please provide a description, in text of what is needed to reproduce problems like this: images and videos are just not a useful thing.
I'm coming back with results! Your messages are confirmed. It turns out that everything was affected by the beta version of MacOS. After rolling back to Big Sur, both problems resolved.
Thanks so much Shawn and ignis-volens for looking at the problem from the outside and helping me solve it 🔥
I want to make a little painting program. So i am going over if it's even possible. As with all good painting programs it needs to have pressure sensitivity. And i don't think i have ever come across anyway to get pressure sensitivity of mouse/tablet. Is there a workaround.
The thing i have come closest to is touch event that is supposed to have pressure property.
This question has been asked before but that was like in 2009. I am hoping that there would be something available this time.
Chrome apps are also an option.
As far as I know only Firefox support this through a proprietary property on the event object:
var pressure = event.mozPressure;
which keeps a value between 0.0 and 1.0.
Wacom has a plugin that can be installed to give browsers an API to read these sort of values from but I guess it only works with their own tablets.
Hello from the future world of 2022!
There is a PointerEvent API that appears to be supported by major browsers, and pressure can be read out from the PointerEvent.pressure property.
tldraw is an example of a project using this API.
Notes on operating system support for this:
macOS
I can confirm pressure-sensitivity with tldraw's drawing tool works for me on macOS, with either Chrome or Firefox, and a cheap Wacom tablet. Safari did not.
Linux
Chrome on Linux works out of the box; I used the Flatpak version. Your mileage may vary with the .deb or Snap package.
For Firefox, you may need to do this or this to get pressure-sensitivity working. There seems to be a regression with Xinput 2 support being tracked by bug #1207700, so maybe this will be fixed some day.
Windows
I don't imagine you'll have any problems on Windows, but I'm unable to test.
If you were interested in creating a web-based paint program in 2022, you might have a look at Pressure.js, which claims to support both pressure input and "3D Touch" present on some Apple devices in a single library. I have no first-hand experience with this library, though, so I can't back up those claims.
It's true this comes 9 years too late for your project. Sorry about that. But this question ranks high in search results for "pressure sensitivity javascript api," so perhaps it can still be useful to someone.
I have this annoying bug in MS Expression Web 4 SP2, weird GUI quirks: you can see in the picture: like parts of the display isn't being painted. I had this before, and solved it by uninstalling something, but the problem is that I don't remember what it was... (I installed Exp.Web in fresh Win7 PC, and step by step installing everything, until this problem came up.)
Anybody came across this issue maybe ?
The problem is a program called FileBox eXtender. It's excellent program I use to pin windows to have them always on top (never be hidden by other windows), because it does its job and it's free. Unfortunately, MS-Expression (Web, Blend, etc...) doesn't get along with it, so I excluded it (somewhere in FileBox-eXtender's options) and now it's o.k.
I need to build a fairly simple app but it needs to work on both PC and Mac.
It also needs to be redistributable on a disc or usb drive as a standalone desktop app.
Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run.
I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install.
However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality.
Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill.
What would you recommend or suggest I check out?
Any suggestion much appreciated
EDIT:
There's a few more discussions on mono usage (though no real conclusion):
Here and Here
EDIT2:
Titanium could also fit the bill maybe, will check it out.
Any more comments from anyone?
EDIT3 (one year on): It's actually been almost a year since I posted that question but it seems some people still come across it every now and then, and even contribute an answer, even a year later.
Thought I'd update the question a bit. I did not get around to try the tcl/tk option at the end, time constraint and the uncertainty of the compatibility to different os versions led me to discard that as an option.
I did try Titanium for a bit but though the first impressions were ok, they really are pushing the mobile platform more than anything, and imho, the desktop implementation suffers a bit from that lack of attention. There are also some report of problems with some visual studio runtime on some OSs (can't remember the details now though).. So discarded that too.
I ended up going with XULRunner. The two major appeals were:
Firefox seems to work out of the box on most OS version, so I took it as good faith that a XULRunner app would likely be compatible with most system. Saved me a lot of testing and it turned out that it did run really well on all platforms, there hasn't been a single report of not being able to start the app
It's Javascript baby! Language learning curve was minimal. The main thing to work out is what the additional xpcom interfaces are and how to query them.
On the down side:
I thought troubleshooting errors was a sometimes difficult task, the venkman debugger is kinda clunky, ended up using the console more than anything.
The sqlite interface is a great asset for a desktop app but I often struggled to find relevant error infos when something didn't work - maybe i was doing it wrong.
It took a little while to work out how to package the app as a standalone app for both PC and Mac. The final approach was to have a "shell" mac app and a shell pc app and a couple of "compile" script that would copy the shells and add the custom source code onto it in the correct location.
One last potential issue for some, due to the nature of xulrunner apps, your source code will be deployed with the app, you can use obfuscation if you want but that's something to keep in mind if you want to protect your intellectual property
All in all, great platform for a cross-platform app. I'd highly recommend it.
Tcl/Tk has one of the best packaging solutions out there. You can easily wrap a cross-platform application (implemented in a fully working virtual filesystem) with a platform-specific binary to get a single file executable for just about any modern desktop system. Search google for the terms starkit, starpack and tclkit. Such wrapped binaries are tiny in comparison to many executables these days.
Many deride Tk as being "old" or "immature" but it's one of the oldest, most stable toolkits out there. It uses native widgets when such widgets exist.
One significant drawback of Tcl/Tk, however, is that it lacks any sort of printing support. If your application needs to print you'll have to be a bit creative. There are platform-specific solutions, and the ability to generate postscript documents, and libraries to create pdfs, but it takes a little extra effort.
Java is probably your best bet, although not all Windows PCs will necessarily have Java (most should). JavaFX is new enough you can't count on it - you'll probably find a lot of machines running Java 1.5 or (shudder) 1.4. I believe recent Mac OS still ships with 1.5 (latest version may have changed to 1.6).
Consider JavaFX
It would run everywhere with a modern JRE ..!
AIR could be an option, but only if you don't mind distributing two different files (the offline runtime installer and your app), and expecting the user to run one and then the other. You do have to submit an online form at Adobe's site saying you agree to distribute the offline installer as-is, rather than digging out individual DLLs or whatever, before they give you the installer.
Unfortunately there's currently no way to get both an AIR app and the runtime to install from one file though. I'm not sure what the deal with Shu is, or whether it's doing anything that isn't kosher.
i would recommended zink. it has all the functionalities you require for desktop. however, the las time i used it it was a bit glitchy.
i was hung up by trying to write a 6M file to the disk. thought it trough and changed the code to write 512K chunks at a time (3min work, fast).
probably it still has some little annoying glitches like making you think on root lvl but the ease of use and the features are just way too sweet to ignore.
