Constant TRACKPAD_IS_TOUCH_ONLY

pub const TRACKPAD_IS_TOUCH_ONLY: &'static str;
Available on crate feature dep_sdl3 only.
Expand description

A variable controlling whether trackpads should be treated as touch devices.

On macOS (and possibly other platforms in the future), SDL will report touches on a trackpad as mouse input, which is generally what users expect from this device; however, these are often actually full multitouch-capable touch devices, so it might be preferable to some apps to treat them as such.

The variable can be set to the following values:

  • “0”: Trackpad will send mouse events. (default)
  • “1”: Trackpad will send touch events.

This hint should be set before SDL is initialized.

§Availability

This hint is available since SDL 3.2.0.
