--- Comment #10 from Nate Graham <n...@kde.org> --- I'm starting to wonder if this is fixable. In plasma-framework/src/scriptengines/qml/plasmoid/containmentinterface.cpp, we accumulate scroll angle deltas from QWheelEvent::angleDelta(), under the assumption that 120 is one scroll click, at which point the "I did a scroll" event fired. This works fine for mouse wheels, but for a touchpad, it results in a very small finger movement producing one scroll event. Ideally we would want for a larger finger movement to be required. A value between 240 and 360 produces a better result for my touchpad, but makes it unusably slow for mouse wheels. We need a way to distinguish between when the event comes from a mouse wheel and when it comes from a touchpad. QWheelEvent::pixelDelta() is supposedly used for this, but it always produces 0, and the Qt documentation says that it's unreliable on X11 and should not be used. :/ Not sure how to proceed. -- You are receiving this mail because: You are watching all bug changes.
