Increase the Mouse Routing Efficiency In Browse Mode

[nvaccessAuto]

Reported by parham on 2012-01-05 07:56
When in browse mode and trying to activate the hover event of an item, pressing insert+numpadDivide (or insert+shift+f9 in case of the laptop layout) does not always route the mouse pointer exactly to that element. This is not always reproducible even on the same page, but sometimes the algorithm doesn't work (E.G. I am in the WordPress dashboard and I choose the list number five in the dashboard menu, but the mouse gets routed to item 3).

It currently routes to the top left corner of the underlying object. However, this may be problematic if the object has borders. It'd probably make sense to change this to the centre of the object, which is consistent with this command's normal behaviour when text cannot be mapped to points.

Milestone changed from None to 2012.1

comment:1 implemented in 60d4718, which should hopefully fix your particular issue.

This issue has come back, perhaps now in another form.

On a page which NVDA worked fine with previously, I cannot route the mouse as I could before (I.E. the hover event doesn't get triggered). Here's the debug warning log. I hope it helps:

Sorry. This doesn't help. We need a URL and steps to reproduce if possible.

Btw, are you saying the fix in 60d4718 introduced this problem? Are you certain of this? Please test with NVDA 2011.3 if not. Thanks.

No, this changeset doesn't create this problem.

I have done further testing on this. I have this application running on three computers with three IPs (192.168.3.12, 192.168.3.118, and 92.50.13.8). Strangely, this issue only happens on 192.168.3.118. There doesn't seem to be a logical connection, but I thought there might be a programmatic reason.

Note that the applications are all the same, just three copies running simultaneously.

Try pressing control+0 to reset page zoom. There is a bug in Firefox (MozillaBug:650241, fixed in Firefox 13) where location information is often incorrect when the page is zoomed. You may have accidentally zoomed the page at some point.

Also, check whether the browser is maximised or restored on the working machines and do the same on the non-working machine.

Yes, ctrl+0 disabled zoom and now it works perfectly.

Also, check whether the browser is maximised or restored on the working machines and do the same on the non-working machine.

I was accessing all those IPs that I mentioned using the same machine. It works on two of them, and didn't work on the third one. It was because I had zoomed the page when accessing 192.168.3.118, and Firefox remembered this setting. So every time I tried using other IPs, there would be no zoom, but when I opened 192.168.3.118, the zoom would be back.
