Improve touchpad scroll handling for convergence workflows while avoiding gesture conflicts.
- make SwipeArea handle angleDelta-based touchpad wheel streams and phase-less sequences safely
- wire topbar ActionDrawerOpenSurface to virtual desktop info and horizontal workspace switching logic
- add dock pager wheel switching in FavouritesBar for the vertical wheel axis environments deliver
- prevent wallpaper/home surface touchpad scroll from opening app drawer in convergence
- extend convergence invariant checks for the new gesture paths
Strut windows committed zero height to layer-shell during
early init, causing a protocol error and session exit. Wrap
height and exclusionZone in Math.max(1, ...) for top bar
and dock.
Persisted gamingModeEnabled=true with hardcoded
gameCenterOpen=false hid panels with no overlay visible.
Initialize gameCenterOpen from the stored setting.
Fix HUD visibility regression from an emergency visible:true
override. Various null-guard and positioning fixes from
static analysis across the gaming shell QML.
loadPackage + setPath can produce an invalid package if the shell
package is missing. Guard with isValid() to avoid passing a bad
package to setKPackage. Add the QML_SINGLETON factory that the
QML engine requires for proper singleton instantiation.
AppletHost: setPreloadFullRepresentation(true) does not guarantee
fullRepresentationItem() is non-null on return — the applet loads
asynchronously. Wire a single-shot connection to
fullRepresentationItemChanged to emit appletReady() when the item
arrives.
TaskWidget: operationDescription() can return null for an unknown
operation name; bail out rather than dereferencing it.
Long-pressing a mapped quick-settings tile in convergence
mode opens a floating popup with the Plasma applet UI
instead of launching System Settings. Unmapped tiles still
open Settings.
AppletHost creates a standalone Corona to host applets
outside the shell containment tree.
Emit clicked() when a press-and-release occurs without any swipe
movement. This allows consumers to distinguish taps from swipe
gestures on the same surface.
These changes make the navigation and status bar accessible from within fullscreen applications by allowing the user to tap on the top or tap or drag on the bottom of the screen.
Also, since the top panel is now over top of all fullscreen applications, this moves the action drawer swipe area back into the status bar.

This adds support for touchpad scrolling in various shell components, such as the lockscreen, homescreen and action drawer.
Currently TODO because it appears to be very buggy when there is a control underneath that also accepts touchpad input (ex. flickable). The touchpad scroll start appears to get called by Qt, but not the end event, so I am unable to "let go" of the flick. Not sure if it's a wayland issue.
This also appears to not work in the nested KWin session, not sure if it's because of libinput or something
SwipeArea requires 10px to differentiate between taps and swipes. HomeScreenState uses a further 10px to differentiate between vertical and horizontal swipes. This MR combines the swipe detection together so that we only need 10px rather than 20px for gesture detection.
