Disable flow mode mouse scrolling to the next/prevous page.

[OShead]

Is there any way that I can disable this feature. I usually play audio and follow the along with the text and sometimes, (most of the time) I don't want to move on to the next page. When I navigate to the bottom of the page while using the mouse wheel while still having some of the text and audio to play, it automatically jumps to the next page because I've hit the bottom. It's pretty annoying and upsets the flow.

So, just to sum up. I'd like to use the scroll wheel to move up and down a page but not to jump to the next or the previous page. There's obivously a feature that's been added to the viewer that makes this happen, is it possible to have a check box to toggle it on or off?

Thanks.

I am confused. There are no pages in flow mode, that's the whole point of flow mode. If you mean internal file boundaries (aka chapters) there is a setting to prevent scrolling with keys from doing this in the viewer preferences under Scrolling behavior. So enable that setting and scroll with keys instead of th emouse wheel.

Did you know you can scroll down using the spacebar (when the window has focus)?
Same with Preview (pane) in the Editor

I got that thanks and am now using that method. It stops scrolling at the end and will only jump to next page (chapter) if i lift the key and press it again. That's perfectly fine for my use.

I do have another question if you don't mind. I play an audio file when the page is opened and use an eventlistener with javascript to detect the end of the audio file. I tried to call with javascript the next page but it doesn't work. And it seems I can't call any of the keyboard shortcuts you have setup either without user interaction.

Is there a way I can access the calibre api (or something ) with javascript to go to next page exactly the way Ctrl+PageDown does?

Thanks for the reply, I've been through the shortcut settings and resorted to using the up down arrows as kovid describes.

No, calibre's UI cannot be accessed from book JS for obvious security reasons.

I tried various methods, but they came back with what looked like a wrapped version of the page with starting like this... {"version":1,"tree":{"n":"

          audioPlayer.addEventListener("ended", function(e){
            console.log("audio ended");
            //window.open('part021.html', '_self');
            //window.location.replace("part02.html");
            //window.location.assign("part02.html");
            //location.replace("part021.html");
            //location.href = "part021.html";
          });

Do you know of anyway around this?

Just for context, they are short one minute long language lessons with text and sometimes I like to listen in background while doing something else like make dinner and etc... So I'd just like for it to play through the book, page after page, without user interaction.

Ok. so how i've been able to get around it for now is this. Knowing that each audio file is around 1 min long, give or take 10 seconds and each page fits without scrolling, I have set Autoscroll to go to next page @ 75 seconds. The audio is usually finished playing by then and the next page autoplays the next audio. It works for this book with short chapters but longer texts of various sizes is another story.

Edit... The longest I can set "seconds to pause" for autoscroll is 50 seconds. anyway... back to the drawing board.

So this is where I'm at with this. I'm not a programmer and just having a little fun with it. If not learning a little in the process.

The audio plays on the page and text is highlighted to correspond with the currently playing audio. I have just added an ability to scroll along with the text or and to go to the location of where ever the audio is playing. It works well for longer chapters. Now looking for a way to jump to next page (chapter) when the audio finishes playing.

Here's a little demo... https://youtu.be/OM8sPTydAP4
