Trait tfc::InfoContext[−][src]

pub trait InfoContext {
    fn cursor_location(&self) -> Result<(i32, i32), Error>;

    fn screen_size(&self) -> Result<(i32, i32), Error>;
}

A context that supports fetching device information.

Implementors of this trait are able to fetch the state of the device.

Platform Differences

This trait isn't implemented for the Wayland (or more accurately: not X11) context. It is simply not possible to obtain this information under Wayland.
