Description Aleksey Gavrilov 2018-03-27 17:14:07 UTC 
I have the left-handed option (which swaps left and right mouse buttons) enabled.

I also have mouse gestures enabled on button 3 (right button before swap)

In windows for which no gestures are configured, mouse clicks behave as expected (right butto sends left click to the window and vice versa).

In windows for which gestures are configured, pressing right button sends left mouse click to the window, as expected. Pressing left button initiates gesture recognition, as expected. However, pressing left button and immediately releasing it, such that no gesture is performed, sends left click to the window instead of right click.

In https://invent.kde.org/plasma/khotkeys/-/blob/master/libkhotkeysprivate/triggers/gestures.cpp

void Gesture::mouse_replay(bool release_P)
{
    bool was_enabled = _enabled;
    enable(false);
    Mouse::send_mouse_button(button, release_P);
    enable(was_enabled);
}

It seems mouse_replay doesn't consider left-handed option.

Can you still reproduce the bug on 5.23?
Comment 3 Aleksey Gavrilov 2021-11-06 08:12:11 UTC 
No, seems to work correctly now.

As announced in https://pointieststick.com/2023/07/26/what-we-plan-to-remove-in-plasma-6/ and https://community.kde.org/Plasma/Plasma_6#Removals, I'm afraid KHotKeys has reached end-of-life in Plasma 6. Accordingly, all bug reports and feature requests for it must be closed now.

Most of what KHotKeys could do can already be done with the newer KGlobalAccel system in Plasma 6. A few features such as mouse gestures and triggering conditions based on changes to window states are not yet implemented in the new system. These will be added in the future if and when resources materialize for them, and/or when a kind soul submits patches to implement them! :) Meanwhile, the 3rd-party "Mouse Actions" app (https://github.com/jersou/mouse-actions) may be usable for implementing your own mouse gestures again.

Thanks for your understanding, everyone.
