From 8e3addb7e73122a4c89ef347b03f714ff75a253a Mon Sep 17 00:00:00 2001 From: Aleksandr Borodetckii Date: Mon, 2 Jun 2025 04:01:06 +0300 Subject: DolphinView: Conform to global scroll speed One scroll with the mouse wheel is supposed to scroll the view by QApplication::wheelScrollLines, however previous to this commit Dolphin scrolled the view by QApplication::wheelScrollLines^2 instead, which was wrong and way too much. This commit fixes this by defining one line height as the height of the current default font. This value is multiplied by QApplication::wheelScrollLines to determine the scroll amount per mouse wheel scroll. In details view mode however, where there really are rows to go by, this commit makes sure to always scroll by full rows. The number of rows to scroll is determined by rounding up from the scroll amount used in the other view modes.
