Description unblended_icing552 2023-09-27 11:10:42 UTC
SUMMARY
(Desktop -> Add Widgets)
In "Widgets" menu, swiping upwards and downwards almost always trigger the dragging operation over scrolling. This makes it difficult to navigate through the widgets menu using only touchscreen.


STEPS TO REPRODUCE
1. Use a device with touchscreen
2. Use Wayland session
3. On the desktop, long press and hold the empty area of the desktop until a pop-up appears at the top of the screen
4. Tap "Add Widgets", the Widgets menu appears on the left
5. try to swipe up and down with only one finger to navigate through the menu

OBSERVED RESULT
Most of the time, swiping with only one finger causes a widget in the menu to be dragged, instead of properly scrolling through the menu. You need to use two fingers (touching only one item) to successfully scroll.

EXPECTED RESULT
The menu should scroll with only one finger swiping up and down. A widget should be dragged only on touch-and-hold, similar to Android does with the app drawer.

Only start drag and drop from Widget Explorer when dragging horizonally

This way, you can still drag vertically through the list of applets, and then horizontally to start a drag and drop.
