[opensuse] gwenview - awkward scrolling in browse mode (KDE 4.4.2) "release 231"
Guys, I don't know if anyone else has noticed this yet, but when scrolling in browse mode (icon view) in gwenview, the folder don't seem to move. The only thing that seems to happen is the folder names seem to jump up/down the screen when you scroll (with mousewheel up/down) within a folder containing a large number of subfolders. The look is very awkward. It's almost like the folders are stationary and the folder names exist on some type of 'widget layer' and the widget layer is used to simulate scrolling. Has anyone else noticed this? If something like this has been implemented, then the timings are way off, because it doesn't look like scrolling at all. It just looks like the folder names jump from folder-to-folder. -- David C. Rankin, J.D.,P.E.

I'm using Gwenview frequently, but not any problem as you described André den Oudsten -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I know what you mean. Point gwenview at /usr/share and set the zoom level so that 5 or 6 rows of folders are visible, then mouse wheel in the icon view. The folder icons appear to stay in the same place, and the folder names change. It's an illusion because the scroll increment is a multiple of the row height, the same one if you are shooting a film with railings in the background that at a certain speed seem to slow down, stop moving and go backwards. Dolphin scrolls by fractional row increments so it doesn't suffer from this problem. It's only noticeable when you scroll a lot of folders that do not contain pictures, so they don't have thumbnails, but I've talked about it with the Gwenview developer and he has appropriated the wheelEvent code from Dolphin that does this, so you should see a change in a future release of Gwenview.

AAAHHHAAA!!, I knew I wasn't crazy. What is strange is why am I just noticing it now with gwenview? Is it new to gwenview in 4.4.2 or has some other change brought this to light? Regardless, I'm glad to see work being done on scroll. One thing that has been very frustrating is that scrolling in K4 is like a box of chocolates -- you never know what your are going to get. Sometimes scrolling with the mousewheel (or clicking up/down in the open part of the scrollbar) kde4 has always scrolled more than 1 page or ended up with 1/2 the upper or lower row of icons cut off or worst of all skipping past several rows that you never get to see. It was so bad at times I would have to go back through lists to find items that had simply been scrolled past without ever being shown. Glad to see it finally getting some CPR. -- David C.

I don't know, but Gwenview did not do anything special on wheel events, so I guess that it's the default Qt scroll behaviour (which Dolphin modifies)

Heheh, I don't think anyone ever added 'Make Scrolling Experience Consistent' to the KDE HIG.

Since this behaviour is not specified and is open to modification, I guess app developers just do what they want. The cut-off behaviour is in Dolphin, although I think this is a consequence of the fractional row height scroll to avoid your original complaint. If you notice any apps scrolling more than one viewport height (causing scroll past without showing) this is a bug. If you did a survey of different apps's behaviour I'm sure it would stimulate a spec and standardisation effort.
