Version: (using KDE KDE 3.3.1) Installed from: Debian testing/unstable Packages [Taken from comment #6 in Bug 76082 by "Rutger ter Borg"] When a user scrolls a document, it is sometimes difficult to keep track of where you stopped reading, especially when scrolling by larger amounts (Page up/down keys). There needs to be a visual aid to help the user remember where they stopped reading (just like you would in real life put your finger on the line you are reading before you look away from the book). There are two good ways of doing this: - put a line at the position of the page boundary before the scroll started - highlight/change the background of the region which was visible before the scroll perhaps a choice of both Some more details: - Visual aid should appear immediately when the scroll starts, and remain visible for the duration of the scroll (while the user holds down the key/button or keeps turning the scroll wheel) - The effect should fade out after a timeout - The colour and timeout should be configurable This Bug _does not_ depend on Bug 76082, but they both address the same issue - keeping track of your reading position while scrolling. If smooth scroll is implemented, the fade timeout should start after the scroll effect is complete.

this can't be implemented in kdelibs. Applications have to implement it themselves as not all scroll views are displaying documents. And I think there is already a wish for khtml
Why can't it be implemented for any scroll view - even those that do not contain documents ? I would expect this to be useful for any view that has a scrollable area much larger then the visible view. At most there could be an additional option (optional param, another method call, whatever) to disable that behavior - which should be configurable anyway.
I understand that this feature is possible now in Qt4, so I am reopening this bug. In fact, Opera 9 (which is also Qt based) has this feature and it is terrific: it is an exceptional usability feature and I don't know how we've gotten along without it for so long. See the "Opera Scroll Marker" on this page: http://www.opera.com/docs/changelogs/linux/960/
A mockup and suggestions for this feature have been posted on KDE-Look: http://www.kde-look.org/content/show.php/Scrollbar+marker+line?content=61517

Scrolling is handled by the Qt library. Please suggest this feature to Qt developers at Nokia via https://bugreports.qt.nokia.com/secure/Dashboard.jspa
