Fast horizontal scrolling

[GluedToTheScreen]

Maybe I missed an option, but the old chap/links timeline had a nice feature where SHIFT-mousewheel scrolled the timeline horizontally... fast.

With vis, it seems you get zoom with or without the shift key +wheel

Is there a way to re-enable that functionality?

thanks again.

Thanks, good idea to add these kind of shortcut keys again. We too need a key+scroll combination to scroll vertically (see #152 (comment))

I seem to be close but no joy...

In vis.js around 7935, I found the Range.prototype._onMouseWheel function and wrapped a hack around one line:

    if (event.shiftKey) {
        this.move(delta);
    }
    else {
        this.zoom(scale, pointerDate, delta);  //ORIGINAL LINE
    }

This SEEMS to move INVISIBLY move the timeline. No movement of elements is seen... no pan left/right.. BUT, when you do any little thing to manually move the timeline, the "moved" timeline and elements will instantly appear.

While the horizontal scroll seems to work under the surface, you cannot see it happen.

I tried this.redraw() but that didn't help.

Any suggestions?

thanks

I see the methods Range.move and Range.moveTo are not used in the library, maybe some leftover of an earlier version. Like with Range.zoom, these methods should call Range.setRange(start, end) in the end to actually apply the new start and end. This method Range.setRange validates the new start and end, and emits the rangechange and rangechanged events, which will trigger a redraw of the Timeline. Note that this rangechanged event should not be fired repeatedly when moving the Timeline, so that needs to be adressed too (see also #397)

+1 for improved navigation options for the end-user

I'm not sure about any "standards" for this, but [1] SHIFT+mousewheel could work for horizontol scrolling (like you would have with http://www.simile-widgets.org/timeline/ ... which actually always scrolls horizontally); [2] CTRL+mousewheel might not be correct to change... as it is the browser zoom in Chrome, IE, and FF; so it feels more natural to keep it as current, zooming like mousewheel does; or pass on to browser zooming [3] perhaps ALT+mousewheel for vertical scrolling (see #152 (comment))

At the moment, it seems that [1], [2], [3] are all intercepted in v3.7.1 when the user is on the timeline; they all map to zooming in and out. This is a good start ;-)

Outside of the timeline, [1] might bring the user back (or forward) in browser navigation; [2] appears to be a browser zoom across browsers; [3] might behave like [2] on Linux (using FF) but seems unused elsewhere.

Note however that I'm no expert...

Hi,

Over the last year a lot of feature requests have been made. We have just introduced our new website which has a list of the requested features. We have placed this request on that list.

The list can be found here:
http://visjs.org/featureRequests.html

An explaination of the new system can be found here:
http://visjs.org/blog.html#New\ website\ for\ vis.js!

I would like to stress that this does not mean we abandon this request. Discussion here will continue if needed on this feature but we will close it to keep our Github issue page more of a bug-todo list.

Future feature requests will still be made here and then added to the website by us.

Regards,

Alex

Reopening as Feature-Request issue (see #2114).
Everybody: Please feel free to implement this!

@mojoaxel I've implemented a verticalScroll option, so I think this can be closed. It doesn't have a ctrlKey but that's another feature. No?

You are write! This is implemented!

[yotamberk]

@mojoaxel I'm rereading this feature request and I think we can still improve what is in the develop branch. I should add horizontalScrollKey and verticalScrollKey and maybe scrollSpeed could be cool. Anyways, lots of additions can be added to this
