?Limit Scrolling to Current Page?

[PHK]

Is there a way to prevent scrolling from one page to another?

Suppose you are in a multipage document file and are zoomed-in to an area of a page and want to change the focus of the document window to another area of the same page using the scroll wheel on your mouse, if you have one. If you scroll up to the upper limit of the current page, the document window focus will shift to the middle of the bottom-most portion of the page above, if there is one. Or it will perform similarly if you scroll down and off the current page.

I would like the option of not allowing the focus to shift pages when driven by scrolling with a scroll wheel. Is that there already but I cannot find it? If not, could that be considered as a development?

Hi PHK,

You might try Ribbon Layout. If the page size is larger than the window, the wheel will not switch pages as you wish，and even in that case, you can switch pages with Shift + wheel. On the other hand, if the page size is displayed within the window, you can switch pages with wheel.

Since the actual book is turned left to right, it is quite natural for the pages to flow left to right when viewed on the screen. If the book is displayed in Ribbon Layout & continuous mode, annotations that span pages with arrows, for example, will appear naturally. With Standard Layout, however, the arrows are not connected, so the reader will not understand what is going on.

Standard Layout is commonly used in applications around the world, including PDF-XCE, but I believe that Ribbon Layout is more suitable for reading documents in depth. All sorts of reasons probably contribute to the rationale for the Ribbon Layout: almost all computer monitors are horizontal, the human eye has a wider viewing angle on the left and right than on the top and bottom, they are placed horizontally on either side of the face, and they can look around with less muscle tension than on the top and bottom.

I think the Ribbon Layout is one of the great features of PDF-XCE. However, since Ribbon Layout is currently incomplete in its support for full-screen mode, it is necessary to increase the number of users who use Ribbon Layout and to increase the user's voice.

Hoping that the above information will be of some help to you.

Yes, it does immensely! However, I see it slightly differently.

It seems to me that the differentiation between the two layout modes is whether the scroll action (in zoomed-in, single page view) moves the document window focus to the next page by scrolling horizontally or vertically. If you are in 'Standard Layout' mode, vertical scrolling will bring the next page into the document window whereas horizontal scrolling will not leave the page. And 'Ribbon Layout' mode does just the opposite: scroll horizontally to bring the next page into focus and scrolling vertically will keep the current page in the document window (but see below).

But there is no obvious on-screen indicator of which mode is operative, which I find a bit annoying. The user must click on the Page Layout icon under the View tab (in the default setup) and then on the little arrow to see which mode.

It would be nice to have a small icon somewhere on the screen (bottom ribbon, for instance) indicating which. Perhaps this could be considered as a UI enhancement.

And I see a weird anamoly in Ribbon Layout mode where vertical scrolling will allow the document window focus to scroll off the page entirely into nothingness. So, say you have a page that is 33"x68" (upper left corner anchorred at 0x0 by default). If you scroll down through the 68th inch of the page you are in nothingness until 119" south is reached. Likewise, if you scroll up you will leave the page at 0" and can continue on in nothingness until 51" north is reached. 51" vacant top + 68" document + 51" vacant bottom for a total possible scroll travel of 170", somewhat less than the absolute page maximum of 200". At least that is what I am experiencing.

isn't it also possible to use single page view , and disable page change by scroll wheel, so that you have to press your arrow keys or some button in the UI in pdf xce to go to the next page?

HI guys,

indeed if you use "single page mode" then the panning is restricted to just that page.

Regarding the Ribbon Layout being incomplete, this is true and we acknowledge this. On discussing this with the development team leader he has agreed that we should formalizer the efforts to improve this. To that end I have raised the associated support ticket, RTRT#6374: Feature Request :: Editor :: Improvements to Ribbon Layout.. It's formally in the pipeline to improve this.

I do not anticipate seeing these improvements in the initial V10 release, but a subsequent one down the road.

I hope that helps.

That's not my experience. What I am saying is that in Single Page, Standard Page Layout mode, yes it only shows a single page at a time, but if you scroll up with the mouse scroll wheel it will change the page in the document window to the previous page. And down will put the next page in the window. I don't want a new page in the window.

Hello, PHK

"Scrolling" and "panning" are two different tasks, if you middle click and drag (or use the hand tool) to "pan" through the document, you will not be able to exit the single page you are viewing. Only by scrolling, or clicking the "next/prev page" buttons can you navigate to the next page.

We do not currently plan to offer any functions which will prevent scrolling from proceeding to the next page.

Kind regards,

Even in the current build, the Customize Toolbar feature allows you to place the "Standard Layout" and "Ribbon Layout" commands for displaying the current layout mode anywhere you want. In fact, I have been using the two commands side by side for a long time. The IDs for each command are as follows.

• cmd.view.layout.standard
• cmd.view.layout.ribbon

It would be nice if this setting were promoted to the default, so that Ribbon Layout would be better known to users.

Hello rakunavi,

Thanks for your suggestions. Indeed the Ribbon layout is not too obvious for someone not searching for it, but it is also true that the majority of PDF files are intended to be read 'vertically' rather than horizontally, and most people are used to this from many other software products that display content which normally scrolls up/down mostly. So for now there are no plans to make the ribbon layout the default, but I will check with the devs to see if we can make this setting a bit more obvious to people new to our software.

Kind regards,
Stefan

Hi Stefan, thank you for your comment.

If I would wish to make Ribbon Layout the default, I would be kicked out by other forum participants. It is 1000% absolutely inconceivable to hope for such a thing.

It is just my hope that the default setting with Standard Layout and Ribbon Layout buttons side by side would be better to appeal the existence of Ribbon Layout to users.

I apologize for any misunderstanding due to my poor English. I must be more diligent and improve my English skills.

Best regards,
rakunavi

Hello rakunavi,

And I do apologise for not understanding your request fully initially!
English is not my first language either - so no worries! Yours is also very good so no need to apologise there!

Kind regards,
Stefan

Good point.

But north/south scrolling performs weirdly in Ribbon Layout mode because scrolling will continue off the page into nothingness which is lesss than ideal.

I guess if I don't want to have to choose which format I want, Standard or Ribbon, which only changes the direction on scrolling to another page I need to have single-page files where there is no other page to scroll to.

I fail to understand why Tracker is opposed to giving users the option to limit scrolling to the current page.

English IS or WAS my first language but that fails to prevent my miscommunications in that language. Even worse in others.

Hello, PHK

Vertical scrolling will only proceed into "nothingness" as you described if there is a page in the document which is vertically larger than the page you are currently viewing. If all pages are the same, it is contstrained exactly as the horizontal scrolling is in the standard page layout.
Also, it s worth noting that if you zoom out to a "fit page" or smaller zoom level (far enough our that the right side scrollbar vanishes), scrolling the mousewheel will go left/right in the document (effectively acting as next/previous page functions).

Kind regards,

[rakunavi]

Hi PHK,

There is a bug about Ribbon Layout, so I will comment on it for your reference.

• Issue that occurs when documents with different page heights are displayed in Ribbon Layout, Single Page, and Fit Page
  https://forum.pdf-xchange.com/viewtopic.php?t=39384

It occurs when the following three conditions are met.

• Page layout is set to "Ribbon Layout"
• Display mode is set to non-continuous "Single Page"
• Magnification is set to "Fit Page"

Best regards,
rakunavi

Many thanks, Rakunavi.
