4 months ago Current reality:
- Yes, Qt now has better built-in gestures, and it is not hard to do #1407. However, real hardware is needed to test and connect gestures to actions.
- The webengine widget on macOS has rich gestures built-in. Just don't add/touch/modify them.
For GD's in-house implementation, there are maybe some bugs if user has unusual setups (unusual to 10 years ago), such as:
- Wayland -> GD's implementation simply doesn't work because the screen coordinate cannot be obtained, and the relevant methods are deprecated.
- Wayland appears to implement gesture recognition on the system's side (via libinput?) simliar to macOS instead of letting apps do it on their own.
- Hi-Dpi or large screen -> GD's implementation only needs very small movement to trigger the gestures. Again, deprecated methods are used.
- The webengine widget appears to have some built-in gestures for Linux/Windows like on macOS too. Conflict?
(BTW, I welcome sponsorship to buy me a high-precision trackpad/touchscreen that supports 3-figures to improve gesture support 😅)
