SUMMARY
In Android Krita, a long press registers as a right-click.

STEPS TO REPRODUCE
1. Using a stylus (Wacom Pro Pen 3/tablet included) or finger, touch the colour picker, layer opacity slider, canvas scroll bar, etc.
2. Keep touching without lifting and move very slowly.

OBSERVED RESULT
After approximately 0.3 seconds, a right-click is triggered, releasing the held element.
For the colour picker, this confirms the selected colour. For layer opacity, it opens the numerical input screen. For scroll bars, the right-click menu appears.

EXPECTED RESULT
The held element should remain movable during the press.

SOFTWARE/OS VERSIONS
Android version: Android 14
Devices: Wacom MovinkPad 11

Sort of related to Bug 506042. Krita sets QT_ANDROID_ENABLE_RIGHT_MOUSE_FROM_LONG_PRESS, which causes the described behavior.

I'm increasingly thinking that this right-click emulation is the wrong solution. What a long-press should do is summon a context menu on appropriate widgets, not issue a right-click. indiscriminately Will ask in the K-A thread if there is other cases I'm not thinking of here that would break if this were changed (assuming it's possible.)

Comment 2 dra.w.p.il.e+bugskde 2025-10-07 02:11:09 UTC

Resolved by making long-presses open context menus directly instead of issuing a right-click, making sliders no longer enter edit mode when holding still on them (that now happens on double-clicks instead) and disregarding scroll bars as a thing you can long-press on, among other things that never have a useful context menu assigned to them.
