(This is the documentation for SDL3, which is the current stable version. SDL2 was the previous version!)

SDL_HINT_TRACKPAD_IS_TOUCH_ONLY

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

Header File

Defined in <SDL3/SDL_hints.h>

Syntax

#define SDL_HINT_TRACKPAD_IS_TOUCH_ONLY "SDL_TRACKPAD_IS_TOUCH_ONLY"

Remarks

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.

Version

This hint is available since SDL 3.1.3.
