XYplorer Beta Club

Currently I have no time for this, but it is on my list.

Generally I recommend caching the thumbnails.

Something to look at that MIGHT help a bit is take a look at your mouse control settings.
Don't know which mouse you are using. I'm using a MS wireless intellimouse. It's free wheeling with no clicks, so maybe it's why a lot of the time scrolling isn't a problem.
But there are times it is with all programs and it is the scroll wheel distance setting.
I go into the mouse settings and check the scroll distance and it will show a 17. I change it to scroll 1 line at a time and use acceleration. Everything works great for 1 to a number of days. All of the sudden scrolling is jerky and going a bunch of lines at a time. Especially in spreadsheets.
I go back to the mouse settings and by magic it's reset itself to 17 lines again. Change it back to 1 and apply and all is good.


It doesn't

I have spent many hours going carefully through all the configuration settings AND have searched the configuration settings file carefully for some sort of "wait" or "delay" setting for this extremely annoying super-speed scrolling. I have about 1000 images in my primary image folder and when this happens it will scroll up or down 30 or 40 rows in about 1/2 second!

It is so annoying, I actually quit using XY for some time. I came back to XY and spent all the time I mentioned trying to set up everything very carefully. Having done so, noting has affected this annoying scrollbar behavior. I like this XY app, and you say you may not have time to offer some options here, but this behavior is so annoying I will be forced to shelve XYplorer permanently if a solution is not made available.

I do understand if you don't have time to properly fix this app, but I am "begging" you to do something. Windows Explorer and all the other explorer wannabes just don't measure up at all.

Hi and welcome,

I'd love to fix it but it's so hard to reproduce. I'm now on a new system (Win8) and I can't seem to find a way to see it.

Don

In the last days I also had 2 problems, working with thumbnails.

1) Scrolling per mousewheel scrolls a complete page per notch: it only should scroll 1 'line' (of thumbnails). (No problem to scroll 10 notches for 10 lines...)

2) If, while thumbs are being built, i click for some time (say 2 sec) on the arrow for scrolling down (right scrollbar), scrolling didn't stop after release, even after moving mouse away from the arrow. Only any further click somewhere could stop this.

1) Should it? Not sure. Who says so?
2) Cannot repro.

Much of #1 relies on system-wide user settings, as kodyman alluded to earlier.

Not sure what Don would have to do but for .NET you must check MouseWheelScrollLines or WheelScrollLines to determine how many lines the user has configured the system to scroll for a single wheel notch - if negative the user has it configured to scroll one page at a time. Then use the event's delta and the wheel_delta to determine how many of those units to scroll.


There's no set rule of one notch always equals one page or x lines.

Yes. I know and I'm doing all this ever since wheel is supported.

I understood PeterH that Thumbs should get extra treatment.

I probably could repro the phenomenon and fix it. Try next beta...

To 2) 14.10.0100 really seems to have fixed the continueous scrolling problem. At least for several tests all was OK

To 1) I misunderstood a part of the problem: on a small screen 3.5 lines of (big) thumbnails were shown - so scroll by 1 notch scrolled a full page. On a bigger screen I saw that just 3 rows were scrolled.

But yes: I think it's a difference if 3 of 25 lines of text, or 3 of 3 rows of thumbnails are being scrolled as a minimum. So I'd prefer a smaller amount for thumbnails. Even only 1 would be OK.
(Just had a look at irfanview thumbnails: it scrolls by 1.5 lines of (smaller) thumbs )
(Nikon ViewNX: scrolls by 0.5 lines - I don't understand that )

But OK: that seems to show that other programs have a special treatment on scrolling thumbs.

XY does not scroll a page per notch, but a certain number of lines OR a page (whatever is smaller). That certain number of lines is configurable Windows-wide.

Your 1st sentence is what I just understood.

But I think to configure the same value for text and for thumbnails isn't good! For text 3 lines are 10% of a page, while for thumbs it might be a complete page.

In praxis: I often need to look at several pictures together - scrolling by page of 3 rows makes this unpractical. Here I have my finger on the wheel - but must position to and click on the small arrow on scrollbar

This might be the reason why other programs use different values when scrolling thumbs...

Well, technically that would be easy, but no time currently.

...but thanks to understand!
