Detect if the mouse is available on the current platform

SDL Development

I’m trying to develop some common code for macOS and iOS and struggling with detecting if the mouse is supported on the current system. Internally SDL_GetMouse would be null for iOS, but I can’t find any public API to detect if there is a mouse, and consequently cursors and such.

A simple public SDL_HasMouse() call would be sufficient for my case. With a trivial body of checking if SDL_GetMouse returns null or not.

Thanks in advance.

Checking if SDL_GetDefaultCursor() returns a non-null value might work for you.

Thanks! It worked. However, it is relying on a side effect, direct API would be better…

Because touch actions by default get translated into mouse actions (e.g. a tap on the screen generates a left-mouse-click event) I’m not at all sure I’d want a SDL_HasMouse() function to return FALSE on a touchscreen platform such as Android or iOS. To that extent isn’t the presence or otherwise of a cursor a more direct test of what you are interested in?
