Hi Robert,
macOS will take care of emulating mouse, so most apps should work out of the box.
There’s a patch up to add native touch support here: https://codereview.qt-project.org/c/qt/qtbase/+/783930
Though there are still rough edges around Qt that needs to be solved.
Cheers,
Tor Arne

Hi,
Apple announced their first laptop with a touch screen.
Is there any need to update/correct our applications?
Is there any support in Qt missed to handle it?
Thank you,
Kind regards,
Robert Iakobashvili
Dear Tor Arne,
Thank you for your prompt reply and the patch.

Is it makes sense to enable for all widgets: Qt::WA_AcceptTouchEvents
or Apple-simulated mouse events will work better although not in all cases?

I do not recommend enabling Qt::WA_AcceptTouchEvents for all widgets.

For one, it enables touch events from trackpads as well, which has a performance impact.
Secondly, doing so will disable the OS level emulation of mouse events for that widget, so unless it actually handles touch fully things will break.
An example of that is that Qt Widgets does not have touch-based scrolling. Nor does it respond to long-presses to trigger context menus.

These are things I’m working on improving.

Cheers,
Tor Arne
