Thanks. MathJax is an interesting tool. It can help make for excellent presentations.
As to the touch screen. You're right. It should be a low priority as few touch screens are out at this time. My wife and I had to replace our laptops recently. I was not interested in the touch screen at the time but they happened to have touch screens. I found the touch screen quite useful for apps which supported it. Since I got a touch screen I just had to try to use it in J. A little tricky, but I was able to use the move event by itself to tell J to update the webview control. Not really reliable without a way to know when the finger touched or was removed from the webview control. It would not be practical to provide all the events that a webview or any other browser be sent directly to J. It is more practical to handle those events in Javascript or whatever is provided by browsers. But it would be really nice if there were a clean and simple interface for Javascript or whatever to communicate with J. Right now such communication is awkward. But such communication would be very useful for all J platforms. On Tue, May 2, 2023 at 7:33 AM bill lam <[email protected]> wrote: > I think webview gesture support is low priority.
