Minor scroll wheel issue

[JohnM]

Hi Don.

v41 seems to fix the second problem. Thanks The first one still occurs however

Seems to be connected with Logitech mice, or?

I don't think that this is to do with Logitech mice because like I say, this also happens on my cr@ppy HP PC at work which has a cr@ppy HP mouse.

Anyway, is the problem related to which control has the focus? Some of the descriptions above seem to suggest that it only happens when the tree was last focused and you then wheel the list.

Yeah, it seems to happen when the focus changes from the list to the tree and back again. If that's any help.

Another question: there are many wheel-scrollable controls in XY. Do you observe this issue only with the main file list?

I've really only noticed the problem on the file list so far.

I hope this helps!

Again, only with the the list??

Hi Don

Yes, it only ever affected the listview.

Although I could not reproduce it, I could produce at least a theory and react accordingly. The next version will show...

Hi Don

Yeow!!!, whatever you did, undo it!!!

Now, instead of the listview missing a scroll down, it scrolls down and immediately flashes back up where it was (the thumb in the scrollbar also flashes down then back up). I sometimes have to scroll down 6 times to get it to stop flashing and actually scroll down and stay there.

Was better the way it was, at least I only had to scroll down/up/down. Now have to scroll down/down/down/down/etc.

Hmm. This is so weird, I have to ask: does anybody else have the same??

[Gandolf]

does anybody else have the same??

No. The scroll behaves exactly as it did - I still miss the first click of wheel rotation when returning to the list.

It's not only a mouse wheel problem.

Tree and list only - no Info panel. XY maximised, but appears not to be relevant.

Select a folder in the tree (call it folder 1) that has more files than will display on the screen.
Move to the bottom of the list by clicking on the space below the scroll bar thumb, and select a file near the bottom.
Select a different folder in the tree (2), also containing more files than will display.
Move to the bottom of the list for that folder and select a file near the bottom. (I have to click twice on the scroll bar to move the thumb - the first click is ignored).
Switch back to folder (1) in the tree.
Then switch back to folder (2) without moving from the tree.
Try to move to the bottom of the list by clicking below the thumb bar.

The thumb bar moves but the list does not.

I hope that helps and is not me being over complicated again!!

Thanks, but your report came a minute too late. I've just finished fixing the bug. I think...

[Gandolf]

I've just finished fixing the bug. I think...

Yep, you got it.

[John Bee]

Yep, you got it.

Not for me it isn't.

I scroll down, the thumb in the scrollbar and the listview contents flashes down then back up. Up to 6 to 8 scroll downs before the listview actually scrolls down and stays down. Then only one scroll down works. But the flashing happens 9 times out of ten.

At least before, I only needed to scroll down/up/down, now its down/down/down/down....... until it stops flashing.

Sorry I can't be of more help Don but the way it is now is no good for me. I think I go back to 0040.

How's your wheel mouse set up? The standard is 6 lines per notch.

[John Bee]

No. I have it setup to scroll one "page" per scroll unit. Always been this way for years. I don't like 3 or 6 lines per scroll.

And yes, I have set it to 6 to test, and it still does it. The way you had it in 0040 is way better than now.

Ok, I think I may have found my crazy scrolling problem.

It is having Show Folder sizes in list turned on, that is doing it.

As soon as I turned it off, no more flashing.

I noticed that when this was happening, XY was taking 30% CPU use and did not stop until I turned this feature off.

Somehow it goes in a loop and when this happens, it affects mouse scrolling.

Aha. Interesting. Again I could not reproduce it.

Actually I plan to do the folder size thing a bit differently in future (and this might en passant solve the issue):
- first list all items
- then calculate the folder sizes, and only for the items currently visible (i.e. items that are within the list's view port)

Hi Don;

Yes, it is a frustrating problem when it doesn't happen all the time with only a few (or one?) can reproduce it.

But after playing with it for a few hours, it seems to happen in folders with a lot of sub-folders with some having many many files in them. It must confuse the gathering of file sizes or something because CPU use start to increase to 30% and sometimes up to 50% for XY and stays there, and does not dissapate until I move away from that folder.

But your idea sounds like it will probably not only fix this, but will mean a massive increase in speed for filling the listview where there is many folders. I can't wait.

...for a few hours... thanks for your time!

Did you check your disk recently? What you are reporting sounds like a file system or hard disk error...

Hi Don;

(This situation only happens with XY with Show Folder size on, nowhere else.)
