--- Comment #7 from Marian Klein <mkleins...@gmail.com> --- I noticed https://community.kde.org/KDE_Visual_Design_Group/Gestures , which is related to this bug. What is the difference between touchpad and touchscreen in operation? There is no direct correspondence (size , aspect ratio) between touchpad and screen/display so touchpad must captures delta/relative moves: If you lift your finger from touchpad and move into another place , the pointer does NOT jump, it continues from where you left it. On the other hand touchscreen has to maintain direct one-to-one correspondence between touch sensor and display to stay in sync, so it needs to capture absolute positions. Jumps in finger must translate as jump in pointer. Other than that, there is not much difference between touchpad and touchscreen. Currently plasma (desktop area) implements : 1) Touchpad moves without holding left button as a relative change of pointer location resulting potentially into hovering or/and change of application focus. 2) touchpad moves with holding left button as dragging /selection. 3) application can be openned by 3a)left touchpad/mouse button single click or double click once the pointer is hovering over icon 3b) single click or double click on touchpad once the pointer is hovering over an icon 4) touchscreen (one finger) moves (or maybe small consecutive jumps) as dragging/selection (as if holding left mouse/touchpad button) To treat both touchpad and touchscreen in the same fashion. Can we have a virtual on screen "sticky left touchscreen button" on plasma to change between default hovering/focus change mode and selection/dragging mode? This way we can unify touchpad and touchscreen behaviour and reuse touchpad settings for touchscreen as generic touch sensors devices. -- You are receiving this mail because: You are watching all bug changes.
