Re: How to use eventHandler.requestEvents
Hi, I see. Do you know if this event is mapped to an existing NvDA event? One way to find out is running AccEvent, part of Windows SDK tools. If not, it will involve some runtime under the hood changes to let NvDA recognize this event (not sure how to do this for Microsoft Active Accessibility, but it’s a bit involved in UI Automation; based on Windows 10 App Essentials add-on source code in front of me, it involves runtime manipulation of UIA events map; at least that’s the high-level overview, so let’s discuss this on a different list). Cheers, Joseph

I think I misunderstand not only requestEvents but also some other event related stuff in NVDA, so I'll check your suggested example and lurk around in the suggested groups to figure out what I actually want.

Re: How to use eventHandler.requestEvents
Hi, Where did you see “focusChanged” event defined in NVDA? I can’t see that event defined in my copy of NVDA screen reader source code at the moment. To answer the original question at hand: without going into details (something reserved for NVDA Add-ons list), eventHandler.requestEvents function is designed to let app modules respond to app events in the background. This is useful if you need to let NvDA monitor changes to an app control from everywhere. For example, an app might raise name change event in an app, and you may wish to let NVDA announce changes to this control from everywhere. A practical example in use is StationPlaylist add-on where NVDA is told to monitor for changes in status bar texts from everywhere. Cheers, Joseph

How to use eventHandler.requestEvents
falkogiepmans@...
Hi all,
Currently I am working on a appModule for SAP, this has its own API and internal events. I would like NVDA to be able to listen to some of those events. One of these events is "FocusChanged", since NVDA does not notice this in SAP. My idea was to use requestEvents as follows: Example Code class AppModule(appModuleHandler.AppModule): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) eventHandler.requestEvents("FocusChanged", processId=self.processID,windowClassName='someWindow') End Example Code And use this event in some overlayclass: Example Code class SAPClass(IAccessible): def event_FocusChanged(self): ...do something... End Example Code This does not seem to work. Is this what eventHandler.requestEvents is meant for or am I understanding it wrong? I am quite new to events in general but I want to get my head around it. Side question: Is this the place to post these kind of questions? Thanks in advance, Falko

Re: comment section in you tube is not displaying
Quentin Christensen
When I was exploring before, I tried in both Firefox and Chrome. I did find a couple of times it hadn't yet loaded the comments, which was why I thought it was waiting until the focus actually was at the bottom to load them - Either way, it is very slow. I think it's just that sluggishness rather than a browser issue, but that's just a guess.

Re: comment section in you tube is not displaying
Luke Davis
The old trick of pressing Control+End, then shift+2 (to go back to the previous heading level 2), still works to find comments.
However, Youtube is taking longer than ever to show comments now--I just had timings of 3 seconds on one video, and 15 or so on another, before the Shift+2 actually worked. However--I might test this more--if you pause the video (by hitting K, or NVDA+F2 then K), then do the Control+End, Shift+2, that may load the comments quicker. It seemed to in one test I did. I don't generally use Youtube by computer, so YMMV, but these were my results in Firefox just now. -- Luke "In this life there are obstacles, and forces who overcome obstacles.

Re: Error in Firefox
Gene
Uninstalling office causes such a problem but in this case, the registry fixing tool couldn't solve it. Since the problem uninstalling Office causes is unregistered dll files, when you ran system restore, it may have corrected the problem by reverting the registry and now everything is registered. If the problem was something else caused by the uninstallation, System Restore corrected it. You said there was a missing dll file. System Restore would replace it if you ran a restore point from before it was missing.

I suspect there is something wrong with Youtube. On another list there is discussion that comments canbe be seen with Edge but not with one or two other browsers.

The best way I've found to get to it is: 1. Press NVDA+control+f to open NVDA's find function. 2. Type the word "comments" (without quotes) 3. Press ENTER to move to the first instance of the word. 4. Press TAB twice to move past "Sort by" and onto the edit field. I have found that sometimes everything hasn't loaded and it can't find comments. In this case, escape the error dialog, press CONTROL+END to jump to the bottom of the page, then up arrow and it's usually actually at the comments - YouTube seems to load the video and then related / suggested videos, then after that the comments, and sometimes it doesn't load the comments until you actually scroll down to the bottom of the page to get to them.
